How Cannabinoid Receptors Treat Spinal Cord Injury

Cannabinoid (CB) 2 receptor uptick likely occurs to protect cellular systems. CB2 receptors in the brain and gut adapt to specific cells following the loss of CB1 receptors. And a recent study assessed how cannabinoid two receptors treat spinal cord injury by recycling a critical inflammasome.

INFLAMMATORY INJURY AND ILLNESS

Earlier this year, Harvard Medical School released a pivotal study on Covid-19. The virus upticks an inflammasome, leading to a fiery cell death. I hypothesized an endocannabinoid deficiency, a major loss of 2-AG to be exact, as a crucial factor in the viral disease.

2-AG is a CB1 and CB2 receptor agonist. But cannabinoid two receptors are druggable targets that treat disease and injury caused by an inflammasome storm, including one induced by a spinal cord injury.

SPINAL CORD INJURY AND CANNABINOID RECEPTORS

According to a recent study, CB2 receptors help recycle the inflammatory protein known as NLRP3. The inflammasome remains inactive under homeostasis, a function of the endocannabinoid system. But if macrophage cells fail to clear toxins from the body, they warn the immune system, which releases NLRP3 proteins.

The process occurs in numerous diseases and leads to excessive cryopyrin. Proteins must degrade and properly recycle to avoid inflammation and pyroptosis, though. During spinal cord injury, CB2 receptor activation recycles inflammatory proteins via a unique enzymatic process — ubiquitination.

CB2 receptors, in part, boost a nutrient sensor axis (AMPK/ULK1) to recycle proteins. And NLPR3 inflammasome reduction, in turn, regulates neuron and epithelial cell polarity. CB2 receptor agonists can, therefore, regulate autophagy, prevent cell death, and attenuate neuroinflammation.

cannabinoid receptors treat spinal cord injury
“NLRP3 inflammasome structure. The NLRP3 inflammasome is a complex consisting of NLRP3, ASC, and procaspase-1. NLRP3 consists of three regions: the pyrin domain (PYD) in the amino terminus, the NACHT domain, and the leucine-rich repeat domain (LRR) in the carboxy terminus.” — Seok et al. 2021.

A DRUG OR A TERPENE?

Beta-caryophyllene and delta-9 THC agonize CB2 receptors, but THC also targets the cannabinoid one receptor. Pharmaceutical companies failed to synthesize a selective CB2 agonist over the last decade.

The value of a functional and selective CB2 receptor agonist is in the billions, despite caryophyllene’s ubiquitous presence in our food supply. Drugs or terpenes that selectively target cannabinoid two receptors can treat various conditions, including Covid-19 and spinal cord injury, by recycling inflammatory proteins.

10 Health Benefits of CBN

Source: LinkedIn.com | Author: Arnold Benson | Oct 12, 2022

Cannabinol or (CBN) as it is called, is one of the most exciting minor cannabinoids in the cannabis plant. Much of the industry is focused on THC and CBD-based products, but research is slowly uncovering the significant therapeutic potential of minor cannabinoids like CBN on the human body.

How can CBN help medical patients? Does CBN get you high? What are the effects? CBN has many potential health benefits that can aid with everything, from insomnia to seizures and so much more. Here is what you need to know about this up-and-coming cannabinoid.

What Is this Cannabinol (CBN)?

Well CBN is a THC metabolite, for whatever that means. So in aged cannabis plants, tetrahydrocannabinol acid (THCA) degrades to cannabinolic acid (CBNA) when exposed to light and heat. Generally, cannabis plants contain trace amounts of CBN (under 1%). However, CBN concentrations can increase over time. In poor storage conditions, the plant’s THCA can degrade into CBNA, resulting in lower potency, aroma, and flavor. Cannabis processors may use various heating/extraction measures in a vacuum oven or chemical solvents to oxidize THC into CBN. This distinctive minor cannabinoid can offer many benefits for recreational, as well as medical users who make claim to being Very Effective for sleep.

When taken alone, this cannabis compound does not produce a high like THC. So let’s take a look at this in simple terms. In the human body our endocannabinoid systems (ECS), CBN has a low binding affinity with CB1 receptors BUT has a strong affinity with CB2 receptors, although it is still less than the THC. CBN appears to have similar properties as popular cannabinoids like CBD and THC.

Now the Health Benefits of CBN

  • Compared to research into other major cannabinoids like THC and CBD, CBN research is in its infancy stages. While most research into CBN is based on animal studies, researchers are beginning to uncover the potential benefits of CBN. Early research indicates that CBN may help relieve pain, insomnia, inflammation, appetite loss, and much more. CBN has many health benefits, including: Minimally psychoactive, Powerful sedative, Relieves pain, Anti-epileptic, Anti-inflammatory, Inhibits cancer cell growth, Stimulates appetite, Passes transdermal barrier ten times better than THC, Bone growth stimulation, Glaucoma treatment, Antibiotic Properties and additional scientific research is necessary to identify how this “CBN” affects the mind and body and safe ways to treat various health conditions. Simply put, CBN appears to be the cannabinoid that should not be ignored.

1. Potent Sedative –CBN is one of the most sedative cannabinoids in the cannabis plant, especially when used with THC and the myrcene terpene. Research suggests that CBN’s sedative effects can be used as a sleep aid for those who have insomnia. Not only may it help people get to sleep faster, but it may also prolong sleep time. A 5-mg dose of CBN may have the same sedative effect as 10 mg of Valium, a prescription medicine used as a sedative and for treating muscle spasms, anxiety, and alcohol withdrawal.

2. Pain Relief –Current research shows that CBN interacts with neurons involved with pain signaling and perception. These same neurons are affected by capsaicin, an active compound of chili peppers, known for its burning sensation. Capsaicin can be found in topicals and pain relievers. Essentially, CBN may be used to reduce pain.

3. Antibiotic –Studies have shown that CBN and other cannabinoids may be effective in treating MRSA, an infection caused by a type of staph bacteria. This strain of bacteria is becoming increasingly resistant to antibiotics. More research into CBN’s antimicrobial properties may help fight against antibiotic resistance.

4. Anti-Convulsant – THC and CBD products are powerful options in anti-convulsant treatment. CBN is also showing promise as a powerful anti-convulsant. A study on mice found that CBN has strong anti-convulsant properties, especially when used with other cannabinoids. If CBN continues to display anti-convulsive properties for muscle contractions, it may be a promising cannabinoid for patients with epilepsy.

5. Anti-Inflammatory – Cannabinoids can be used for inflammatory conditions such as rheumatoid arthritis and Crohn’s disease. While many cannabinoids have shown positive effects on inflammatory diseases, CBN is another alternative treatment option for those with inflammation. A study on mice found that CBN decreased allergen-induced mucus production.

6. Appetite Stimulant – Appetite loss can be caused by various psychological causes or medical conditions. While certain cannabinoids like CBD can suppress appetite, CBN may stimulate appetite. CBN may be helpful for cancer patients, for example, who may suffer from appetite loss due to cancer treatment.

7. Anti-Cancer – Early research shows that CBN can inhibit and stop cancer cell growth. In one type of lung cancer, CBN and other cannabinoids were found to actually reduce tumor size. While CBN has displayed therapeutic effects in cancer treatment, there is no definitive research showing CBN can manage the disease.

8. Glaucoma Relief – Early research suggests that high doses of CBN may help relieve intraocular pressure, a critical risk factor for glaucoma. CBN also has neuroprotective characteristics that may keep neurons in the back of the eye healthy. This is crazy but there are “Eye Drop Formulations” featuring CBN currently under development for glaucoma therapy.

9. Bone and Skin Health – CBN may have powerful protective properties to aid in bone health. CBN has been shown to activate stem cells in bones to create new bone cells. CBN may also be helpful in bone loss reduction, as a treatment for osteoporosis, and the promotion of bone healing. And in terms of skin health, CBN has been shown to reduce skin cell overgrowth. Topical CBN treatment may have promising effects in psoriasis treatment. In addition, CBN is much more permeable across the transdermal barrier than THC.

10. Neuroprotective – CBN has been shown to have neuroprotective qualities. In a study on animal models, researchers found that CBN showed positive effects when treating subjects with amyotrophic lateral sclerosis (ALS). CBN was shown to delay the onset of ALS. While more research needs to be done on humans, CBN shows promise as a therapeutic tool for neurodegenerative diseases.

FAQs About CBN

Can CBN Get You High? In small doses, CBN does not produce intoxicating effects. Is CBN Legal? While CBN is not explicitly listed under the Controlled Substances Act (CSA), CBN is still Schedule I substance derived from the Cannabis Plant Federally. The CSA defines cannabis as any part of the plant, except for stalks and nonviable seeds. CBN derived from hemp falls in a legal gray area. In some states, hemp-derived CBN products may be legal if they have under 0.3% THC. Every state has different rules and regulations on hemp-derived CBN and other THC analogs.

  • What Are High-CBN Strains? Currently, there are not many high-CBN strains compared to THC and CBD-rich varieties. Most strains have under 1% CBN. Here are a few strains that have slightly over 0.3% CBN. (Lemon Kush, Durban Poison, Blackberry, Bubble Gum, Purple Cadillac and Super Green Crack (What names lol)
  • Can You Buy CBN Online? In legal cannabis markets, CBN products can be purchased from licensed retailers. Hemp-derived CBN products are available from online retailers. Before buying CBN products, ensure they are lab-tested for purity and potency.

Final Thoughts on the Health Benefits of CBN – While THC and CBD may be the primary targets for research, CBN research is in its early stages and is slowly showcasing the health benefits of CBN. As a result, CBN is showing great promise for medical and recreational users and is being introduced into various products, including edibles and topicals.

I am so proud to be part of this movement!

How Biden’s rescheduling of marijuana could affect the US industry

Source: MJ Biz Daily | Author: Chris Roberts | Oct 14, 2022

After a half-century in which marijuana endured the strictest prohibition allowed under the law, President Joe Biden has set in motion a process that could lead to revolutionary changes for federal MJ policy.

It could mean struggling American marijuana companies can finally enjoy long-desired tax relief, or those same firms could lose cannabis entirely to big pharmaceutical companies.

Both outcomes – and many other scenarios – are all possible under the “administrative rescheduling” process the president activated last Thursday, according to legal and scientific experts.

At the same time, an act of Congress could cancel out whatever recommendations emerge from the Justice Department, the Department of Health and Human Services and the alphabet soup of other federal agencies responsible for drug policy now tasked with reviewing how Washington DC handles marijuana.

“Anyone who says they know what will happen doesn’t know what they’re talking about,” said Andrew Kline, senior counsel in the Denver office of the Perkins Coie law firm and former public policy director at the National Cannabis Industry Association.

“There are just too many unknowns at the moment.”

Under federal law, drugs fall into one of six categories, ranging from Schedule 1 to unscheduled.

And there are the five steps of the Controlled Substances Act (CSA), ranging from most to least dangerous – and restricted.

There are also many substances understood to science as “drugs” that are unscheduled.

These include popular (and potentially deadly) tonics such as alcohol and tobacco as well as the intoxicating hemp-derived delta-8 and delta-9 THC products sold online and in barely regulated smoke shops and bodegas unleashed by the 2018 Farm Bill.

The situation is more complex than some observers realize, but here’s a brief review of the rescheduling process, where marijuana could finally end up and what it would mean for the current and future U.S. cannabis industry.

Schedule 1: status quo

Background: Since 1970, cannabis has been classified under Controlled Substances Act of the Richard Nixon era as a Schedule 1 controlled substance, the category for drugs with no recognized medical application, “a high potential for abuse and the potential to create severe psychological and/or physical dependence,” according to the U.S. Drug Enforcement Administration.

Other Schedule 1 drugs include heroin, LSD and peyote.

Even in 1970, the move was controversial. In 2022, this situation “makes no sense,” the president noted last week.

Very famously, marijuana has a “lethal dose” so high it’s never been definitively established in humans, while drugs classified as Schedule 2 have a large and growing body count.

Of the 107,622 Americans killed by a drug overdose in 2021, none died from cannabis while 71,238 died from synthetic opioids such as fentanyl that a doctor could theoretically prescribe, according to the Centers for Disease Control and Prevention.

There is also growing recognition that cannabis has medicinal applications, as former U.S. Surgeon General Vivek Murthy suggested in 2015 and as a 2017 National Academies review echoed.

Though the Schedule 1 status creates an infamous Catch-22 – studies are needed to justify a rescheduling, but Schedule 1 makes cannabis harder to study, a confounding logical pretzel Congress has thus far been unable to untangle – it seems certain that marijuana will be removed from this category, experts agreed.

“Schedule 1 is a fiction,” Kline said. “There’s clear evidence of its medical utility and little evidence of the high potential for abuse.

“There’s no question it should be removed,” he added. “The question is where does it go.”

Business impact: Under Schedule 1, marijuana companies are barred from taking traditional business deductions – thanks to Section 280E of the federal tax code. That has put a major crimp on their earnings. Scientific research involving marijuana also faces heavy restrictions.

Schedule 2: pharmaceutical model

Background: Schedule 2 drugs are like Schedule 1 drugs, with one exception – clinical application with legal availability through a prescription or under supervision from a physician.

These include Adderall and Ritalin as well as cocaine, methamphetamine, fentanyl and other synthetic opioids.

Schedule 2 – the category sought by a rescheduling petition filed in 1972 by the National Organization for the Reform of Marijuana Laws (NORML) and finally rejected in 1994 – is in a way the cannabis industry’s worst nightmare: legal relief and a relaxation of prohibition but availability only via the arduous and expensive U.S. Food and Drug Administration approval process.

Business Impact: Federally legal marijuana would be “subject to tremendous testing and myriad regulatory requirements that are far beyond what states currently implement,” as The Brookings Institution scholars John Hudak and Grace Wallack wrote in 2015, when recreational cannabis sales were underway in several states in much the same fashion they are now across much of the country.

It would also quite likely still be heavily taxed, as Kline and other experts have said. Section 280E prohibits tax deductions for “trade or business” in Schedule 1 or 2 controlled substances that is “prohibited by Federal law or the law of any State in which such trade or business is conducted.”

Schedule 3-4: tax relief, but doctor’s orders

Background: Schedule 3 is where drugs with “a moderate to low potential for physical and psychological dependence,” such as Tylenol with codeine, anabolic steroids and ketamine, live.

This is the threshold “where 280E tax exemption is no longer an issue,” said Shane Pennington, a Denver-based counsel with the Vincente Sederberg law firm.

This is also the classification sought after in the thus-far symbolic bills introduced by the Congressional Cannabis Caucus that have died in committee without a hearing. That is no huge tragedy, as they currently do not stand a chance of passage in the Senate.

Yet, as Pennington observed, this also isn’t what most existing cannabis companies would want, since Schedule 3 drugs are also only generally legally available with a doctor’s authority and, thus, some level of compliance with the FDA approval process.

The same is true with drugs in Schedule 4, which have a “low potential for abuse,” such as Ambien, Ativan and Xanax.

Business impact: It’s here that the fundamental problem with using the Controlled Substances Act to regulate marijuana appears, at least in the cannabis industry’s eyes: You can’t get rid of the FDA, and the FDA process isn’t something that the current industry is built to comply with.

“People need to understand that regardless of the schedule, you’re still subject to the FDCA (Food, Drug and Cosmetic Act),” Pennington said.

“The point is that the model is not built for cannabis.”

Schedule 5: over the counter, or unscheduled?

Background: Schedule 5 drugs are still FDA-approved and regulated, but they are sold over the counter in pharmacies, supermarkets, gas stations and convenience stores like low-codeine cough syrup.

That’s exactly where most big cannabis companies would love to have their products appear – except, as Pennington pointed out, Schedule 5 products are not considered recreational or adult use.

These include cough syrup formulations.

In that analysis, no place on the Controlled Substances Act is appropriate for marijuana at all, though most observers agree that a complete removal from the CSA is something federal authorities are unlikely to recommend.

Business impact: Better from a C-suite and investors’ point of view would be total removal from the CSA – the legal status enjoyed by delta-8 and delta-9 THC products (though some states currently ban hemp-derived products sold outside their state-regulated cannabis industries).

Rescheduling, then, “would have some benefits but could unintentionally impact the 37 state medical (marijuana) programs which could effectively be dismantled were it placed into Schedule 2 or 3,” said David Holland, a New York City-based cannabis attorney.

“There would need to be a tremendous amount of federal regulation and that would only permit medical usage, not responsible adult usage.”

The upshot

What Biden might have unleashed could turn out to be “an unintended shock wave were rescheduling undertaken, rather than descheduling, which would allow the states to decide the issue of medical legalization and how it may be used in each state – medically and/or recreationally,” Holland said.

In this way, administrative rescheduling could herald tax relief and bigger margins for existing publicly traded marijuana companies.

It could also just as easily lead to an end of federal prohibition packaged with U.S. regulations so onerous that newly burdened big firms disappear and cede marijuana to something like the state-recognized small cooperatives that thrived in the early days of medical cannabis.

About the only thing known is that Biden – in making the most consequential step on federal marijuana policy of any president since Nixon – has unleashed a very long, very complex and very unpredictable force on the world that might yet wreak unintended havoc.

Stronger Than Steel? – Hemp Rebar Could Start an Eco-Friendly Movement in Building Materials

Source: Cannabis.net | Author: Joseph Billions | Sep 3, 2022

Researchers from Rensselaer Polytechnic Institute, Troy, New York, confirm that hemp rebar could be a suitable alternative to steel in cement construction. Dan Walczyk, director of the manufacturing innovation center and professor of mechanical engineering, and Alexandros Tsamis, associate director of the Architecture Science and Ecology Center and assistant professor of architecture at Rensselaer Polytechnic, say they have produced an alternative to steel in concrete buildings and various infrastructure projects. Both scientists agree that hemp-based natural fiber-reinforced thermoplastic rebar has the potential to displace steel as the most preferred reinforcing technology in a few years. These hemp rebars are partially guaranteed to eliminate corrosion challenges, and they are more durable than steel bars.

Rebar is a crucial component in the frameworks of cement buildings. They help construct perfectly standing and durable skeletal frameworks for convention infrastructure projects. On its own, concrete lacks tensile strength, and this is the primary reason why rebars are used—to provide tensile strength.

The Manufacturing Potential of Hemp

About 150 years ago, before the onset of cannabis prohibition and the criminalization of offenders, hemp was used to produce over 75% of the goods consumed by Americans. The manufacturing of hemp-derived goods was scrapped when the government banned the cultivation and usage of the drug based on the threat of abuse. Currently, hemp is at the forefront of manufacturing discussions due to its undeniable potential to serve humans and the global ecosystem.

At the crucial point of severe environmental degradation and climate change, an environment-friendly crop like hemp could be the world’s savior. Hemp is a biodegradable harvest crop that can derive recyclables, renewables, and reusable products. For products that can’t be recycled, they are guaranteed to degrade into the environment as quickly as possible. Environmentalists who are researching the benefits of hemp claim that the mass production of the crop could go a long way towards limiting global warming effects through the reduction of carbon monoxide compounds in the air.

The industrial use of hemp plants could help produce thousands of essential items needed for day-to-day activities, including plastics, paper, clothing, linen, and drugs. It could also produce several technological tools and building items like rebar.

Hemp and the Steel Industry

Studies at Rensselaer Polytechnic and other reputable institutions point out that hemp could be a perfect replacement for steel. These scientists claim these plants are phenomenal crops meant to be mass-cultivated on industrial scales to produce dozens of products.

For example, the various car parts produced from steel or plastic can be alternatively made from hemp. And hemp is a much stronger and more durable raw material than steel and plastic. Yes, hemp is stronger than both materials and products derived from the crop that have long-lasting lifespans.

The New Study

The preliminary study confirms that hemp possesses better strength capabilities than steel and has a higher chance of substantially reducing greenhouse gas emissions.

The Rensselaer Polytechnic Institute for Energy, Built Environment, and Smart Systems (EBESS) are in charge of this new research. The institute is committed to developing a broad strategy for a durable and cost-effective hemp industry to address the constant climate change challenges in a traditionally powered ecosystem. The institute is an interdisciplinary initiative that the private school believes will close the gap between business, engineering, and design.

Walczyk and Tsamis said the research was borne out of a need for innovative and affordable hemp technologies. They also stated that hemp rebar is not the only technology being researched. These other innovations include new hemp biocomposite processing techniques and the development of decortication technology to separate hemp fibers without reducing their mechanical properties.

More Details

Concrete does not possess the internal strength required to stand on its own without support. Construction workers and engineers use steel rebars to provide tensile or inner strength. Rebars are more sturdy rods, conventionally made from steel, but not long.

The research team at the private research university published that the newly developed hemp rebars can provide the necessary framework for building and infrastructural construction. They also stressed the non-corrosive properties of proposed rebars.

Hemp is not the only material that could replace steel for construction purposes. In 1958, Roger Bacon discovered that graphite whiskers possessed ten times more tensile strength than steel and three times its stiffness. After this discovery, graphite was used to make carbon fibers. Recent findings of hemp claim hemp fibers are much stronger than these carbon fibers.

Another notable material in construction is graphene. The Science Journal discovered that graphene sheets have at least a hundred times the strength of steel. The carbon variant is an excellent conductor of electricity and can be combined with polythene products to allow conductivity. It has also been used to produce super-energy batteries and electric vehicles. The downside to this material is the cost of production. Another reason hemp is famous. The plant mimics many features of graphene, steel, and graphite whiskers. It could store as much energy as graphene and has more tensile strength than steel, and can be mass-produced at cost-effective prices.

Note that for hemp to be mass-produced for day-to-day products and industrial tools or components, there are still a few technical challenges that must be overcome. Some of this includes developing efficient processing methods and equipment that would best fit the hemp materials, manufacturing methods, and property data. Failure to overcome these hurdles would result in low-quality hemp rebar samples, among others.

Bottom Line

Hemp can be used to bring multiple high-end products to reality at far lower costs than steel and other traditional production materials. The ongoing development and research on the potential usefulness of hemp plants will shed more light on this. Rensselaer’s Seed to City Hemp Initiative will not only place the school on the hemp industry radar but also contribute to the progress of the New York engineering, design, business, and hemp industries. This proposed natural fiber-reinforced thermoplastic rebar derived from hemp plants will keep hemp structures intact for a long time.

Note that steel cannot be replaced entirely in the industry because it remains the best option for producing some substantial items and electrical tools.

Largest ever independent study into cannabis use

A £2.5 million study into the effects of cannabis on the brain has been launched by a London university.

The Cannabis & Me study will research environmental and biological factors behind the different effects people experience when using cannabis.

King’s College London want 6,000 people to take part in the investigation, which would be the largest independent study of its kind.

Researchers said the funding from the Medical Research Council would help develop greater understanding of the drug, estimated to be used by 200 million people across the world.

More research is needed about how the drug interacts with the brain so doctors can be more confident when considering prescribing medical cannabis, said lead researcher, Dr Di Forti.

“Cannabis is consumed daily by many recreationally but also for medicinal reasons,” she said.

“But in the UK, the prescription of medicinal cannabis remains rare.

“Our study aims to provide data and tools that can make physicians in the UK and across the world more confident, where appropriate, in prescribing cannabis safely.”

The aim is to understand the link between a user’s biological makeup and the effect cannabis has on them.

Researchers will use a combination of virtual reality, psychological and cognitive analysis, and DNA testing.

They will also look at epigenetics in participants, which is how behaviour and environment can impact the way genes work.

Dr Di Forti said she was particularly interested in uncovering any markers connected to potential problems in users, for example mental health or social problems.

The team is now looking for participants between the ages of 18-45 living in the London area, who are either currently using cannabis or have used it less than three times or never before.

The first step for participants is filling out a 40-minute survey online, external.

More Hemp In Space

Source: HempGazette.com | Author: Terry Lassitenaz | Aug 22, 2022

The USA’s Redwire Corporation is gearing up to enable hemp to be grown in the International Space Station.

In what the company says is the only commercially owned and operated plant growth platform capable of growing from seed to maturity in space, the Redwire Greenhouse could launch in spring next year.

During this mission, Redwire client Dewey Scientific will grow industrial hemp in the greenhouse during a 60-day experiment for a gene expression study. Dewey Scientific is a cannabis-focused firm seeking to increase efficiencies and crop yields while reducing crop inputs.

“We work at the intersection of classical breeding and molecular biology,” states the company.

The hemp experiment is just the first step says Redwire.

“Redwire Greenhouse will expand opportunities for scientific discovery to improve crop production on Earth and enable critical research for crop production in space to benefit future long-duration human spaceflight,” stated Redwire’s Dave Reed.

As well as improving crops on our own planet, it’s something that will also be critical in space  as humanity reaches for the stars – not just for food, but oxygen and water reclamation.

“Increasing the throughput of crop production research in space, through commercially developed capabilities, will be important to deliver critical insights for NASA’s Artemis missions and beyond,” said Mr Reed.

Under the Artemis program, NASA is collaborating with commercial and international partners to establish a sustainable long-term presence on the Moon to prepare for missions to Mars.

This won’t be Redwire’s first acquaintance with the ISS. Its Passive Orbital Nutrient Delivery System (PONDS) devices developed in partnership with Tupperware Brands are already operating on the space station. PONDS was developed for NASA’s Vegetable Production System (Veggie).

This also won’t be the first time industrial hemp has been taken into space. Officially, that occurred in 2019 when seeds from Kentucky-grown hemp were taken to the ISS to assess the stability of the seeds after prolonged exposure to microgravity conditions.

 Trivia: The first plants grown in space were Arabidopsis (rockcress) by the crew of the Soviet Salyut 7 space station back in 1982. Seeds had been taken into space before that.

Building Low-Carbon Hemp Homes

Source: AZOBuild.com | Author: Reginald Davey | Aug 21, 2022

Building new structures from low-carbon and renewable resources is gaining significant attention both within the construction industry and wider society. This article will look at constructing new homes with hemp, a low-carbon, and sustainable material.

The Construction Industry: A Major Contributor to Climate Change

According to the World Economic Forum, the global construction industry contributes around 38% of total global carbon emissions. The number of buildings constructed worldwide every week could fill a city the size of Paris.

Approximately half the carbon emissions produced by a building during its serviceable lifetime are produced during its construction before people even use it. This is known as “embedded carbon”, and materials such as concrete and cement are estimated to be responsible for about 8% of total global carbon emissions.

The construction industry is also responsible for the exploitation of vast amounts of virgin, non-renewable resources, energy, and produces enormous amounts of waste materials during both construction and demolition. Nearly all the waste produced during a building’s lifetime is disposed of in the environment, typically in landfills, losing valuable resources which could otherwise be used to improve the sustainability and circularity of the sector.

Green Strategies in Construction

Recognizing the scale of the issue, the construction industry has focused on strategies to significantly reduce the carbon footprint of new buildings and infrastructure.

Several technologies have been explored in the construction industry, with renewable energy helping to reduce the carbon emissions from sites and being researched for use in the construction of raw materials. In the UK alone, three out of five construction firms have declared interest in using renewable energy sources such as solar or wind power.

Equipment is getting a green upgrade too. Companies have explored the use of environmentally friendly construction equipment, with Hyundai announcing the development of an excavator which is powered by hydrogen fuel cells, with plans to introduce this machinery in 2023.

One of the most interesting areas of sustainable construction is the use of alternative construction materials which can reduce the amount of embedded carbon in new buildings and infrastructure. Numerous sustainable materials have been investigated in studies over the past few decades, with varying degrees of success.

Related Stories

Sustainable construction materials have made their way into the market over the past few years, displacing the use of conventional carbon-intensive materials such as concrete. Examples include geopolymer composites, recycled plastic, recycled wood, rammed earth, bamboo, wool insulation, living rooves, straw bale, Ferrock (a type of recycled material made from materials such as steel and dust), and hemp.

The Use of Hemp in Sustainable Construction

Hemp is an ancient construction material. Over the course of recent history, the use of hemp has been overshadowed by its association with its psychoactive cousin, cannabis. However, there has been renewed interest in the use of hemp for a variety of commercial products, including as a sustainable building material that can offer a low-carbon alternative to conventional materials.

Many building materials based on hemp have been developed by scientists in recent decades, which show excellent commercial promise. Hemp particleboards and chipboards use this eco-friendly plant-derived material and incorporate other fibers such as flax to produce a stronger, lighter, and more moisture-resistant alternative to conventional chipboard.

Hempcrete is a revolutionary concrete-like material that combines industrial hemp hurds (inner cores of hemp plant stems), water, and lime-based binders. Once applied and dried, hempcrete becomes a strong and lightweight building product that can be used in new homes.

Hempcrete offers advantages such as good insulation, less embodied carbon and energy, low flammability, mold and pest resistance, CO2 absorption during curing, increased strength over time, moisture resistance, non-toxicity, and full recyclability.

Hemp provides several benefits for the construction industry and is playing an increasing role in the sector’s net zero carbon aims to meet international climate change mitigation targets by 2050.

Case Study: Common Knowledge – Building Tiny Homes from Hemp

The potential of hemp as an eco-friendly and low-carbon construction alternative is vast, but one social enterprise in Ireland is championing the small benefits of this ancient building material. Teaming with Margent Farm, a hemp producer, Common Knowledge has designed a low-carbon tiny home using hemp.

They have stated that their tiny homes could help people struggling with the cost-of-living and housing crisis. Named Tigin Tiny Homes, they are essentially oversized caravans. Aside from corrugated hemp cladding panels, these homes are made from other sustainable materials such as cork for insulation and natural rubber for flooring tiles. They can be purchased pre-made or people can learn to build their own.

The hemp panels were first used in Flat House, a pioneering zero-carbon project and are constructed out of plant fibers and sugar-based resins from agricultural waste. Both are lightweight and extremely sustainable, and whilst planning regulations in the UK restrict their use in architectural products, this is less so when they are used in mobile construction.

Common Knowledge intends to make the plans for their Tigin Tiny Homes open source, which means that they would be free to use for anyone who wants to build their own. These plans would include architectural designs, materials lists, recommended suppliers, and pricing information.

In Summary

Hemp is an ancient building material that has garnered increased interest in recent years due to the need for sustainable alternatives to conventional materials such as concrete and the urgent requirement to reduce the construction industry’s carbon footprint and limit environmental damage. With innovative projects such as Common Knowledge’s Tigin homes, the future of hemp in the construction industry is looking promising.

U.S. trade group cries foul over proposed strict limits on THC in extracts

A proposed provision in landmark U.S. cannabis legislation under consideration would set an unnecessarily low level for trace amounts of THC in hemp flower-based food products, leading to “the elimination of the substantial majority of the hemp extract and CBD industry,” a trade group has warned.

In a letter sent to main sponsors of the Cannabis Administration and Opportunity Act (CAOA), filed in the Senate last month, the U.S. Hemp Roundtable (USHR), a Kentucky-based trade association, criticized the THC provision in the bill, which sets a limit of 1 milligram of total THC per 100 grams on a dry weight basis, translating into a 0.001% total THC standard.

The CAOA, considered to be the most comprehensive among several cannabis bills currently floating around in the U.S. Congress, is not expected to become law any time soon, but serves as a center of gravity for the discussion of marijuana and hemp policy.

Scope of the CAOA

The bill would recognize the legalization of cannabis by the states and decriminalize, regulate, and tax businesses, offering provisions related to justice, immigration, and enforcement; small business administration; public health; education infrastructure; labor; veterans; banking, housing; and community development.

The U.S. Food & Drug Administration (FDA) would regulate cannabis products through a new Center for Cannabis Products, under provisions in the proposed law. 

“This is an arbitrary and unrealistic standard,” USHR said of the THC limit proposed for hemp-based products. “No full spectrum or broad-spectrum hemp extract would qualify, and likely most CBD isolates would be challenged to comply, given the limitations of current testing technology.

“Indeed, this limit would delegate most, if not all, popular, non-intoxicating CBD and hemp extract products to the adult-use cannabis market,” the group said, urging the bill’s sponsors to reconsider what it called “a misguided standard for intoxication” that is “uniquely onerous and unprecedented.”

Delta-8 should be regulated

In the letter, sent to Sen. Ron Wyden of Oregon, Sen. Cory Booker of New Jersey and Sen. Chuck Schumer of New York, the lead sponsors of the CAOA, USHR called for expanded protections for all non-intoxicating hemp derivatives including CBD and other cannabinoids, legalizing the sale of CBD and other hemp extracts as food and beverage ingredients, and loosening up on who may conduct safety evaluations.

Despite its vigorous defense of CBD, USHR said it supports the CAOA’s effort to regulate psychoactive cannabis products, like delta-8 THC, which is derived from hemp-based CBD. Separate regulatory pathways for non-intoxicating hemp and intoxicating cannabis products should be established, USHR recommended.

The CAOA should be changed to establish a more comprehensive rulemaking process for determining daily serving limits for CBD that invites stakeholder input, USHR also urged.

Task force proposed

In addition to the allowable THC levels for consumer products, USHR said other provisions in current CAOA language could undermine the industry, and urged creation of a task force to also set regulations for daily serving limits for CBD, consider the advisability of the current delta-9 THC limit for hemp plants of 0.3%, and address other potentially intoxicating hemp derivatives.

The task force would include representatives from the U.S. Food & Drug Administration (FDA), the National Institute on Drug Abuse of the National Institutes of Health, hemp growers, manufacturers, processors and distributors, and testing laboratories. 

The group would report findings and offer recommendations within 120 days after being formed, USHR recommended. FDA and other federal agencies would then have 90 days to start the rule-making process to implement the task force’s recommendations.

Reforms move slowly

Observers have said only incremental reform on cannabis is expected in the near future, especially if the Democrats lose the Senate in the 2022 midterm elections. Problems with banking, for example, could be resolved with separate legislation, the SAFE Banking Act, which would finally permit financial institutions to service cannabis companies without fear of reprisal.

While CAOA’s sponsors have said they will not support the SAFE Banking Act in the absence of broader criminal reforms, policy that provides basic financial services for cannabis operators enjoys bi-partisan support in Congress.

The following businesses and organizations are on the USHR board, according to the group’s website: Ananda Hemp (Kentucky), Balanced Health Botanicals (Colorado), Canopy Growth Corporation (Ontario, Canada), CBD American Shaman (Kansas), Cultivated CBD (Minnesota), Curaleaf (Massachusetts), Garden of Life (Florida), GVB Biopharma (Nevada), Hemp Industries Association, Just Brands (Holland), Koi CBD LLC (California), Medterra CBD (California), Recess (New York), Red Mesa Science & Refining (Utah), SC Labs (California), Turning Point Brands (Kentucky), U.S. Hemp Authority, Verge Agritech (United Kingdom), and Zilis (Texas).

Japanese Cannabis Regulation Reform – Finally?

Nearly 75 years since the Cannabis Control Act was enacted, changes are long overdue in Japan

Source: ProjectCBD.org | Author: Naiko Miki | Aug 21, 2022

When it comes to medical cannabis, Japan is way behind the curve.

Way, way behind. There is officially no legal access to medical cannabis in Japan. But some people are finding relief with hemp-derived CBD products, a market that has taken root and is rapidly growing due to a loophole in the law.

CANNABIS IN JAPAN

Cannabis actually has a long history in Japan, dating back to its pre-historic period. Fiber and seeds of hemp have been discovered in the remains of human habitats from the Jomon period (10,000 BC to 300 BC).

Throughout history, hemp was a widely cultivated crop and played a significant role in Japanese daily life. People wore clothes made of hemp, used hemp ropes in a variety of ways, crafted hemp paper, ate seeds, and made oils. Hemp fields were abundant throughout the nation.

Beyond its practical applications, hemp was also revered as sacred plant in our indigenous religion Shintoism and was (and still is) used in various ceremonies.

And cannabis was well regarded as medicine, as well. It was listed in the pharmacopoeia and prescribed to treat asthma, mitigate pain, and enhance sleep, among other uses. Cannabis tinctures and cigarettes were widely available in pharmacies and were advertised in newspapers.

IMPOSED IGNORANCE

This all changed when Japan lost WWII, and the winner – the United States – forced the country to ban cannabis altogether, as a part of the Narcotic Control Act. Japanese hemp farmers – there were more than 37,000 at the time – protested. So the Japanese government negotiated with American occupation army and managed to separate cannabis from the rest of narcotics. They were also able to secure a legal exemption whereby, mature hemp stalks and seeds were permitted under the Cannabis Control Act. Enacted in 1948, this prohibitionist measure has dictated Japanese cannabis policy without revision or modification for nearly 75 years.

Think about it. In 1948, nobody in the world knew that it was THC that made you high. No one knew we had an endocannabinoid system in our body. Nobody knew the scientific basis for how cannabis can help people with a wide range of ailments, which we understand to a great extent today.

Science progressed, but we didn’t. Japan’s Cannabis Control Act was simply imposed upon us. And we Japanese, famous for our obedient nature and deference toward authority, for good or bad, obeyed.

SLOW FOOTSTEPS OF CHANGE

Seven decades later, however, even our reflexive obedience is approaching its limit. News about cannabis law reform and new scientific discoveries “elsewhere in the world” reaches us every day via the internet. The globe is now smaller, the news travels faster.

In 2013, hemp-derived CBD products started to trickle into Japan. Because of the loophole in the Cannabis Control Act, CBD products are legal to import and use as long as the manufacturer declares it was produced from mature hemp stalks, and if it contains no detectable THC. Despite this absurd requirement, the CBD market has shown steady expansion, particularly after 2019, gaining momentum each year, drawing in whole host of new consumers, including children.

Green Zone Japan, an organization founded in 2017 by a Japanese M.D. and myself, helped a 6-month-old boy with Ohtahara Syndrome (early infantile epileptic encephalopathy) obtain therapeutic doses (according to the famous study led by NYU’s Dr. Orrin Devinsky) of a CBD product currently on the Japanese market. The boy’s seizures stopped!

This generated considerable interest – and hope – among Japanese families with epileptic children and their doctors, triggering a chain of events that culminated in a March 2019 announcement by the Ministry of Health, Labor and Welfare (MHLW), Japan’s equivalent of FDA, that it will “allow clinical trials of a cannabis-derived drug to be conducted.”

The drug slated for clinical trials is Epidiolex, pharmaceutical CBD produced by GW Pharma in the UK and approved as a treatment for severe pediatric epilepsy in many countries, including the United States.

GW Pharma’s Japanese entity, formed for this purpose, submitted a formal application to undertake an Epidiolex study, and it has been approved by the health ministry. But the clinical trial has been slow to get off the ground.

Yes, it’s only Epidiolex, a CBD isolate, and, yes, it is only for intractable epilepsy. Nevertheless, the government’s acknowledgment of the possible therapeutic benefits of a cannabis derivative is a big first step toward the legalization of medical cannabis in Japan.

MURKY FUTURE OF MEDICAL CANNABIS

So where do we go from here?

In January 2021, the Japanese health ministry announced that it was planning to review the Cannabis Control Act for a possible reform. This was expected, because if the clinical trial of Epidiolex is successful, the current law, which prohibits use of cannabis for any purpose, including medical, must be changed. A panel comprised of 12 “experts” was formed; after meeting eight times, it submitted a recommendation that identified four areas of reform. Authorization of medical cannabis is one of them. The reform is expected to be addressed during the ordinary Diet (parliament) session in 2023.

The use of whole-plant cannabis should be incorporated into the “crude drug” framework for natural herbs that Japanese people are already familiar with.

This sounds encouraging. However, things are not so simple. The term “medical cannabis” can mean many different things to different people, and it’s not clear what exactly Japanese officials are referring to when they mention the therapeutic use of cannabis.

There is a lot of confusion about this in a country where the illicit use of cannabis for recreational and/or therapeutic purposes is so limited (cannabis-related arrests in Japan were just over a paltry 5,400 in 2021). Some people simply cannot comprehend that it’s possible to use cannabis medicinally. When they hear that medical cannabis is legal in 37 states in the U.S., many Japanese think it means that doctors give cannabis to patients in hospitals. Still others are under the impression that medical cannabis refers exclusively to Epidiolex. Indeed, the majority of Japanese people are not aware of the difference between state-run “medical cannabis programs” and the unregulated nationwide hemp-derived CBD market.

Obviously, education is crucial before we can embark on a productive discussion about how to shape the future of medical cannabis in Japan. I, for one, would love to see the use of whole-plant cannabis incorporated into the “crude drug” framework for natural herbs that Japanese people are already familiar with – in addition to the pharmaceutical approach. And for that to happen, the reform of the current law is necessary.

There is a long way to go before we have a decent medical cannabis program in Japan, but the first step is now being taken.

Colombia’s turn away from prohibition of cannabis will boost the hemp sector

Source: HempToday.net| Author: Hemp Today | June 24, 2021

In a sharp turn from prohibition-based policy, Colombia will look to advantage small cannabis producers and farming cooperatives, according to a government plan under recently elected President Gustavo Petro.

Petro, a former rebel in the M-19 guerrilla group and a longtime legislator, won Colombia’s presidential election last Sunday, cheering hemp and marijuana interests who hope the new president can execute a plan to transition the country from a narco-state through more constructive policies towards cannabis, coca and poppy.

According to the plan: “The cannabis value chain will receive a special boost, in the hands of producers, linking industry and knowledge, as well as the diversification of uses in the field of medicine, textiles and food, among others.”

The strategy is a fundamental shift in the fight against illegal economies that will position Colombia as a cannabis-producing power through avant-garde policies that take advantage of everything the plant offers, the plan suggests.

Export potential

Envisioning an enhanced framework that favors producer families and co-ops through special permitting privileges and technical support intended to boost farming fortunes while also generating tax revenue for the state, the plan calls for clear regulations, robust research and the promotion of cannabis-based products through cooperation among the state, private sector operators and communities.

“In turn, spaces will be opened in international trade with a variety of (cannabis-) derived products,” according to the 54-page plan, which addresses the broader Colombian economy and society.

Rejecting past policies on drugs rooted in criminalization, the plan notes that “The focus on prohibition in dealing with the global drug problem imposed a war on Colombia around the illegal economies of coca, poppy and cannabis.”

‘War has failed’

“This war has failed and the country needs to move towards a new paradigm that brings together global and Latin American will towards a concerted international agenda based on human rights and the construction of peace, the economic transformation of the productive environments without criminalization of growers, the protection of nature, regulation, the judicial submission of criminal organizations and the approach of consumption as a public health issue,” the plan further observes.

Colombia enacted a law late last year that separated low-THC cannabis from medical marijuana and officially cleared industrial hemp from the country’s drug list. That was followed in February by regulations that set a two-tier system for maximum THC levels, with the limit for grain and fiber crops at 0.3%, while production of flowers, commonly processed for CBD, came under a 1.0% THC barrier.

Potential in CBD

The 1.0% THC limit for hemp flowers should facilitate Colombia’s CBD sector because CBD in hemp plants rises in proportion to THC. A growing number of Latin American and Asian countries are moving to the 1.0% barrier from the generally observed global limit of 0.3%, giving them efficiencies in CBD production.

Colombia also earlier this year put in place international trade regulations for medical marijuana, CBD and other cannabinoids to expand exports.

The Petro government’s development strategy also pledges to move away from over-reliance on fossil fuels, ban aerial spraying of exfoliants such as glyphosate, expand social programs, and more aggressively tax the wealthy.
