The Feds Want Researchers To Study ‘Minor’ Cannabinoids And Terpenes In Marijuana

Published

on

Tetrahydrocannabinol (THC)—the marijuana compound known for getting you high—is the most well-know cannabis constituent. In recent years, cannabidiol (CBD) has garnered attention for its non-intoxicating medicinal properties.

Now, the federal government is recruiting researchers to investigate how the dozens of other lesser-known cannabinoids and terpenes work and whether they can treat pain.

It’s going to be a weighty task for any interested parties. There are more than 110 known cannabinoids and 120 terpenes, very few of which have been extensively studied. The federal research project will cover all “minor cannabinoids,” which is defined as anything other than THC, according to a pair of funding notices published by the National Center for Complementary and Integrative Health this week.

“The mechanisms and processes underlying potential contribution of minor cannabinoids and terpenes to pain relief and functional restoration in patients with different pain conditions may be very broad,” the notices state. “This initiative encourages interdisciplinary collaborations by experts from multiple fields—pharmacologists, chemists, physicists, physiologists, neuroscientists, psychologists, endocrinologists, immunologists, geneticists, behavioral scientists, clinicians, and others in relevant fields of inquiry.”

Numerous studies have established that ingredients in marijuana such as THC and CBD effectively treat various types of pain. There’s also some evidence that other cannabinoids and terpenes contribute to the therapeutic efficacy of cannabis, working synergistically to bolster the plant’s overall benefits—a phenomenon called the “entourage effect.”

But there’s still a lot of work to be done to fully understand the mechanisms through which each cannabinoid and terpene influences pain. If researchers can pinpoint which ingredients are best suited for pain relief, it could inform new therapies. For example, there’s evidence that certain cannabinoids can enhance the pain-relieving effects of opioids, the notice states, so discovering exactly which ones achieve that end can hypothetically help patients take lower doses of addictive painkillers.

“The development or identification of novel pain management strategies is a high priority and unmet need. Natural products have historically been a source of novel analgesic compounds developed into pharmaceuticals (e.g., willow bark to aspirin). A growing body of literature suggests that the cannabis plant may have analgesic properties; however, research into cannabis’s potential analgesic properties has been slow.”

In addition to CBD, the feds say they are particularly interested in research on the following compounds: cannabigerol (CBG), cannabinol (CBN), cannabichromene (CBC), myrcene, ß-caryophyllene, limonene, a-terpineol, linalool, a-phellandrene, a-pinene, ß-pinene, terpinene and a-humulene.

The estimated deadline to submit an application for research funding is March 8, 2019.

Psychedelic Therapists Petition Government For Permission To Dose Themselves In Order To Better Treat Patients

Published

on

As a group of terminally ill patients in Canada awaits word from the minister of health on whether they can legally access psychedelic mushrooms for end-of-life care, their team of clinicians has tacked on an additional request: The therapists want to be able to dose themselves, too.

The group behind the request, Victoria, B.C.–based TheraPsil, a nonprofit that aims to expand access to psilocybin-based psychotherapy in Canada, says the additional step of providing safe access for therapists will ensure they gain firsthand experience into the psilocybin’s effects and its applications to psychotherapy.

“The fundamental reason to expose therapists to their own experiences with psychedelics is that, unless you have visited these realms, you are unlikely to understand their importance.”

“Part of ensuring a very high-quality psychedelic treatment for patients is to ensure high-quality training for therapists,” Spencer Hawkswell, TheraPsil’s executive director, told Marijuana Moment in an interview. “It’s greatly beneficial if therapists have had psychedelic therapy themselves.”

Few people, he offered by analogy, “would advise going to a sex therapist who’s never had sex before.”

TheraPsil, founded by clinical psychologist and psychotherapist Bruce Tobin, has been fighting for expanded access to psilocybin end-of-life care for years. In 2017, the group first filed a petition to exempt patients with certain terminal conditions from Canada’s ban on psilocybin. It was reportedly the first time a therapist had asked the Canadian government for such an exemption.

It wasn’t until this past January that TheraPsil finally heard back, Hawkswell said. “After three years of back-and-forth, they got back to us and said, ‘We’re going to be rejecting this application.’” The agency said there was no obvious medical necessity for the psychedelics.

TheraPsil was undaunted. “They say there’s no necessity,” Hawkswell said. “Maybe it’s because they haven’t met that person yet.”

In April, the group helped four more people with terminal illnesses file petitions with Health Canada and Health Minister Patty Hajdu seeking exemptions that will allow them to access psilocybin. In an interview with Marijuana Moment, Hawkswell said patients had gone months so far without a word from Hajdu, who with a stroke of a pen could allow the patients to access the drug.

“What we are working on right now is ramping up our messaging,” Hawkswell said. “We are going to try everything we can to get to the minister to make sure she sees these patients and responds to them.”

Efforts to allow TheraPsil’s clinicians to use psilocybin themselves are more recent. Dr. Sean O’Sullivan, an emergency room physician and psychotherapist who serves on TheraPsil’s board of directors, said the exemptions are necessary so that therapists can be better trained and more familiar with how psychedelics work in a therapeutic setting.

“The fundamental reason to expose therapists to their own experiences with psychedelics is that, unless you have visited these realms, you are unlikely to understand their importance,” O’Sullivan told Marijuana Moment. “The point is to allow therapists to understand the field they’re plowing in.”

Therapists need to be alert and able to recognize how psychedelic experiences manifest themselves in therapy, O’Sullivan said. Patients might bring up material having to do with their own birth, a traumatic experience or interactions with otherworldly beings. “If you’re not attuned to this possibility, not aware of this possibility, then it’s just going to slide by you,” he said. 

“It’s a bit like describing Beethoven’s Fifth,” O’Sullivan added. “You can describe it all you like, but at some point you have to play the music.”

As psychedelic therapy is more widely sought by patients, O’Sullivan said, demand for qualified therapists is likely to go up. “We are expecting that as we get more permission for patients to access psilocybin at the end of life,” he said, “that there will be an increase in demand for therapists that have had that psychedelic experience.”

Public opinion in Canada generally supports allowing access to psilocybin therapy for the terminally ill, TheraPsil says. A poll released by the group last month found that 59 percent of Canadians support legal access. Including respondents who said they were “ambivalent,” TheraPsil said, acceptance increased to 78 percent.

“What’s unreasonable is the political decision” to deny patients access to psilocybin, Hawkswell argued. “It’s not a scientific one, it’s not a democratic one. It’s political.”

Patients facing their imminent death often experience feelings and fears that psychedelics can help to ease, he said. Among them are demoralization, anxiety and depression. Existing treatment includes pharmaceuticals, talk therapy and occasionally inpatient treatment.

Psychedelics play a role in treatment by inducing what Hawkswell and others refer to as a “mystical experience”—a collection of psychoactive and sometimes spiritual events that accompany a psychedelic journey. The experience can reorient a person’s way of thinking, dissolving barriers between an individual and the world around them. For end-of-life patients, he explained, it can help them embrace that death “is natural—just as natural as being born.”

Practitioners note that psychedelic therapy doesn’t work the same way as many other pharmaceutical drugs, such as antidepressants or even medical marijuana. Patients usually take those substances under their own supervision and allow them to work in the background. With therapeutic use of psilocybin and other psychedelics, patients typically take the drug and undergo guided psychotherapy. Psychedelics’ unusual, sometimes disorienting effects are believed to allow patients to better approach and engage obstacles, then emerge with a fresh perspective.

Another psychedelic therapy group, Field Trip, which uses ketamine in therapy, describes the treatment on their website as a way “to press reset on your mental health.”

The emerging promise of psychedelics in recent years have caught the attention of academics, public policy reformers and even the U.S. government. Last month, the University of North Carolina (UNC) announced a $27 million project funded by the department of defense to research and develop psychedelics-inspired drugs.

That project’s researchers seem to believe they can separate psychedelics from what they describe as “disorienting” side effects, despite what Hawkswell and others say about the importance of a “mystical experience.”

“Although drugs like ketamine and potentially psilocybin have rapid antidepressant actions, their hallucinogenic, addictive, and disorienting side effects make their clinical use limited,” said Bryan L. Roth, a professor of pharmacology at UNC School of Medicine and the research team’s leader. The government partnership, UNC said, “aims to create new medications to effectively and rapidly treat depression, anxiety, and substance abuse without major side effects.”

In September of last year, Johns Hopkins University announced the launch of the nation’s first-ever psychedelic research center, a $17-million project to study the use of psychedelics to treat conditions such as opioid use disorder, Alzheimer’s disease, depression, anxiety and post-traumatic stress disorder.

Meanwhile, activists in the United States have advocated for state- and local-level reforms to research, decriminalize and in some cases even legalize psychedelics themselves.

At the municipal level, Denver became the first U.S. city to enact such a reform, with voters in May 2019 approving a measure to effectively decriminalize possession of psilocybin mushrooms. Soon after, officials in Oakland, California, decriminalized possession of all plant- and fungi-based psychedelics. In January of this year, Oakland activists unveiled plans to allow go further and legalize the commercial sale of natural entheogenic substances. That same month in nearby Santa Cruz, the City Council effectively decriminalized psychedelics by voting to make the enforcement of laws against them among the city’s lowest enforcement priorities.

Reformers are now pushing for similar changes in other jurisdictions. In Washington, D.C. this month, Decriminalize Nature D.C. submitted signatures to qualify a measure for November’s ballot that would decriminalize all natural psychedelic drugs, including psilocybin, ayahuasca and ibogaine.

Other reform efforts are ongoing in Oregon, where voters later this year will decide whether to legalize psilocybin therapy—the very therapy TheraPsil’s patients are pushing Canadian Health Minister Hajdu to allow. Oregon voters will also see a separate measure to decriminalize the possession of all drugs and expand access to treatment for problem use on their November ballot.

Lawmakers in Hawaii earlier this year approved a plan to study psilocybin mushrooms’ medical applications with the goal of eventually legalizing access.

In Canada, for now, psilocybin remains illegal. Hawkswell of TheraPsil, however, believes a constellation of other national policies—including medical marijuana, safe injection sites, and physician-assisted dying—support extending psilocybin access to patients in palliative care. And Canada already permits certain religious groups to use ayahuasca as religious sacrament, Hawkswell noted.

“At this point psilocybin is a reasonable medical choice for these individuals,” he told Marijuana Moment. “This is about the minister being compassionate and using her ministerial abilities to help give patients access to something that’s going to help them.”

Patients waiting to hear back from Hajdu’s office, he said, don’t have time to wait for lengthy, bureaucratic processes. “We’re not just going to keep waiting,” he told Marijuana Moment. “We do have a legal team prepared, but that’s all I’ll say.”

CBD-Infused Mouthwash Works Better Than Regular Products, Industry Study Shows

Published

on

Is marijuana the future of mouthwash? Companies racing to develop cannabis-based health products say cannabidiol (CBD) and other cannabis-derived compounds are emerging as promising new tools to prevent oral health issues such as plaque and gingivitis.

In a recent study out of Belgium, researchers reported that cannabinoid-infused mouthwash was just as effective at killing certain plaque-related oral bacteria as chlorhexidine, an active ingredient in many prescription mouthwashes. The cannabinoid mouthwash was also more effective at killing bacteria than two popular over-the-counter products.

Authors said the efficacy of the mouthwashes, which separately contained CBD and cannabigerol (CBG), “demonstrate the potential of cannabinoids in developing efficient and safer mouthwash products and next generation oral care products.”

“Most of the reported studies show chlorhexidine containing mouthwash as the most effective mouthwash, however tooth staining is an unacceptable side effect of chlorhexidine,” the study says. “Mouthwash products with cannabinoids infusion offer a safer and effective alternative without any fluorides or alcohol.”

The study, published late last month in the peer-reviewed Journal of Cannabis Research, evaluated mouthwashes made by CannIBite, a Belgium-based company that develops cannabinoid-based dental products. The company designed and funded by the study, and Veronica Stahl, a dental practitioner and the founder of CannIBite, was one of the two co-authors.

“To our knowledge this is the first report on such efficient mouthwash product with natural key ingredients including cannabinoids and without any kind of fluoride or alcohol.”

The products tested do not include THC, the main intoxicating ingredient in marijuana.

Traditional mouthwashes serve a variety of purposes. Most freshen breath, and simple swishing (even with water alone) can remove food and other particles stuck between teeth.

A major reason for using mouthwash is to reduce harmful oral bacteria that can build up and cause problems such as plaque and gingivitis. As the study notes, chlorhexidine is considered the industry-standard microbial rinse, and people with periodontal diseases are frequently prescribed mouthwashes containing the drug, though some evidence suggests it can also pose health threats by disrupting beneficial bacteria.

In any case, mouthwash today is a multibillion-dollar industry, and companies that make cannabis-derived health products now want a piece of it.

In the study, oral bacteria from plaque samples of 72 adults were grown in a lab and then treated with fives different mouthwashes: a solution of 0.2 percent chlorhexidine, a solution with CBD and spearmint oil, a solution with CBG and spearmint oil, and two common over-the-counter products—one with essential oils and alcohol as well as an alcohol-free mouthwash with fluoride. After periods of either 24 or 36 hours, the samples were measured to see how the mouthwashes affected bacterial growth.

Results of the experiment indicated that the two cannabinoid-infused mouthwashes significantly inhibited the growth of bacteria—on par with the chlorhexidine. The two over-the-counter mouthwashes, meanwhile, had little to no detectable effect.

“Cannabinoids (CBD / CBG) infused mouthwashes together with other natural key ingredients shows promising bactericidal activity in vitro against total-culturable aerobic bacterial content in dental plaque,” the study says, “with efficiency equivalent to or better than that of the gold standard (0.2% chlorhexidine).”

“Cannabinoid infused mouthwash products perform equal or better than that of chlorhexidine 0.2%”

Photos of agar plates published along with the study underscore the findings. Areas treated with cannabinoid mouthwashes or the chlorhexidine solution appear as circles free of visible bacteria. Samples treated with over-the-counter mouthwashes are covered in a filmy, speckled haze.

Given that chlorhexidine has side effects including tooth discoloration, the study says, cannabinoid-based mouthwashes could offer appealing alternatives that are more effective at killing germs than over-the-counter products.

“Based on our in vitro study, the cannabinoids infused CannIBite mouthwash products offer a much safer, efficient and natural alternative to alcohol and/or fluoride containing mouthwashes,” the authors wrote. “It will be interesting to study the in vivo performance of CannIBite mouthwash products in future to examine for other properties such as tooth discoloration and to examine the oral health benefits.”

CannIBite, which also makes toothpaste and a “protective oral spray,” has patents pending for the application of cannabinoids in dental care. But the company is hardly alone in trying to capitalize on cannabis in oral hygiene. Other companies, such as Impression Healthcare in Australia and San Diego-based Axim Biotechnologies, which also make cannabis-based oral-care products, are testing CBD toothpaste and mouthwash formulas of their own.

John W. Huemoeller II, CEO of Axim, told Forbes last month that “CBD is a powerful antibiotic and anti-inflammatory, so we have found it has great benefits in relation to oral care after year of offering our patented CBD-based chewing gum.”

With companies scrambling to roll out new products to curious customers, it could be only a matter of time before more cannabinoid-based dental products make their way to store shelves.

“As CBD comes to light as a health supplement with a range of potential treatments,” Huemoeller said, “the FDA is already feeling the pressure from the CBD industry and its consumers to allow the non-psychoactive compound to be added into foods and beverages.”

‘Lazy Stoner’ Stereotype Smashed By Study Finding Marijuana Consumers Exercise More

Published

on

Does marijuana ruin an exercise routine? You might be surprised. A new study of older Americans found that cannabis consumers tended to do more formal exercise and engage in more physical activities than non-consumers during the course of a four-month trial.

While authors cautioned the findings are preliminary, they contribute to a growing body of evidence challenging the lazy-stoner stereotype.

“Compared to older adult nonusers,” says the study, out of the University of Colorado at Boulder, “older adult cannabis users had lower [body mass index] at the beginning of an exercise intervention study, engaged in more weekly exercise days during the intervention, and were engaging in more exercise-related activities at the conclusion of the intervention.”

In other words, not only were adults over 60 who used marijuana generally in better shape than their peers who abstained from cannabis, they were also more responsive to an assigned four-month “exercise intervention trial”—essentially a regimen of physical activity prescribed by a clinician.

“These findings suggest that it may be easier for older adults who endorse using cannabis to increase and maintain their exercise behavior, potentially because cannabis users have lower body weight than their non-using peers,” wrote the study’s authors, a team at CU’s Department of Neuroscience and Psychology. “At minimum, the evidence suggests that cannabis use does not hinder older adults’ ability to engage in physical activity, to participate in a supervised exercise program, or to increase their fitness as a result of physical activity.”

“In this study, current cannabis use was associated with lower BMI and more exercise behavior in healthy older adults wishing to increase their physical activity.”

Researchers said the analysis, published this month, is especially important because more and more older Americans are consuming marijuana for medical or personal use. “Adults over the age of 50,” the study notes, “are the fastest-growing population of cannabis consumers in the US, with national prevalence rates estimated at up to 9.1% in 2013.” Of that group, people 65 and older showed even greater increases in use.

While those numbers may be several years old, the trend of rising marijuana use among older adults has continued.

“We haven’t seen a big spike in consumption” across most age groups, then-Colorado Gov. John Hickenlooper (D) told Rolling Stone in 2018. “The only increase in consumption is among senior citizens, which we think is either Baby Boomers coming home to roost or arthritis and the aches and pains of growing older—people finding that marijuana is better pain solution than opioids or other things.”

Yet with so many older Americans failing to meet recommended daily activity levels, the researchers in the new study wanted to better understand how cannabis might affect exercise routines.

“Given the plethora of negative health consequences associated with inactivity and the protective factors associated with exercise,” they wrote, “efforts must be made to understand factors, like cannabis use, that may affect older adults’ engagement in exercise.”

The study looked at American adults age 60 and older who researchers classified as sedentary, defined as completing less than 80 minutes of moderate physical activity per week. Some were assigned to a training program of moderate physical activity, while others were put in a program with low-intensity exercises. A total of 164 participants completed the study through the eight-week checkpoint, with 153 making it through the 16-week timepoint.

Researchers measured participants’ body mass index (BMI) and other health parameters at the beginning, midpoint and end of the study period. Participants also self-reported their exercise behavior in journals. All participants’ exercise programs included supervised training at the research facility three days per week, the paper notes. “Thus, we would expect both groups to be exercising a minimum of 3 days per week.”

“These preliminary data suggest that current cannabis use status is not associated with a negative impact on fitness and efforts to increase exercise in sedentary older adults.”

Researchers admit they’re not entirely sure why cannabis use is associated with lower BMI scores or why people who consumed marijuana were better at sticking to their workout schedules. “Future work,” the paper says, “should employ methods that allow for a target exploration of the mechanisms by which cannabis might be associated with exercise, be it via lower body weight, increased enjoyment, decreased pain, or faster recovery.” All of those potential factors, the team noted, have been hinted at by existing research.

A separate study out of the University of Colorado published last year found that a majority of marijuana consumers reported that cannabis use before or after exercising improves the experience and aids recovery.

The new study highlights an association between cannabis use and exercise, but it leaves many questions unanswered. Researchers didn’t ask participants, for example, about whether they used marijuana before, during or after their exercise. And the study’s measure of cannabis use, the authors wrote, “was coarse and lacked detail,” such as how often and how much marijuana each participant consumed.

“We did not query what form of administration (ie, smoked, vaporized, edible, topical) or cannabinoid content (ie, THC and/or CBD potency) was used,” the study says. “We also did not query whether users’ perceptions of any relationship between cannabis use and exercise, such as increased enjoyment of and/or recovery from exercise, or decreased perceptions of pain, might be driving the association between cannabis group membership and exercise.”

Nor did the researchers ask participants about any negative side-effects of their marijuana use.

Limitations aside, the researchers argue that their findings should encourage further research into how marijuana and exercise might coexist. “It may be that different types of exercise, such as those that that require minimal fine motor coordination or present low injury risk, might be most positively associated with cannabis use,” they write.

Perhaps most optimistically, the authors suggest cannabis could even be used to encourage older adults to stay active. “Whereas the results are preliminary,” the study says, “with both more extensive and rigorous additional research needed, the discovery of a role for cannabis as a potential facilitator of physical activity among older adults may hold promise.”

The paper begins on page 420 of the July edition of the American Journal on Health Behavior.
