Hemp-Derived CBD Helps Chronic Pain Patients Reduce Opioid Use, Study Finds

Published

on

Chronic pain patients consuming hemp-derived cannabidiol, or CBD, on a daily basis for eight weeks reported a decrease in the opioid medications they needed, a new study reports.

“This is a prospective, single-arm cohort study for the potential role of cannabinoids as an alternative for opioids,” the paper states. “The results indicate that using the CBD-rich extract enabled our patients to reduce or eliminate opioids with significant improvement in their quality of life indices.”

The study, published this month in Postgraduate Medicine, sheds new light on the potential benefits of CBD extracted from hemp, a crop that became federally legal under the 2018 Farm Bill, although the Food and Drug Administration has yet to issue finalized guidelines that would allow CBD to be sold in dietary supplements and food products.

Researchers recruited 131 patients who obtain their care from the same pain clinic; 97 completed the eight-week follow-up period. All had been diagnosed with chronic pain and were taking opioid medications for relief.

For the study, participants were given a 60-count bottle of hemp-derived, CBD-rich soft gels. Each gel, according to the study, contained 15.7 mg CBD, 0.5 mg THC, 0.3 mg cannabidivarin, 0.9 mg cannabidiolic acid, 0.8 mg cannabichrome, and less than 1 percent of a botanical terpene blend. Nearly all (91) took two gel caps a day, totaling 30 mg of CBD; three participants opted not to use the hemp extract at all.

“CBD could significantly reduce opioid use and improve chronic pain and sleep quality among patients who are currently using opioids for pain management.”

Researchers asked participants to complete a series of questionnaires to access various factors at the onset of the study, at the four-week mark and at the eight-week point. Among them: their pain intensity level, how much their pain disrupted their lives, the quality of their sleep and how willing they were to cut back on opioids.

Of the total 94 participants who took CBD regularly, 50 reported they were able to reduce opioid medications at week 8. The authors also note: “Additional reductions in polypharmacy on the medication receipt were noted; six participants reported reducing or eliminating their anxiety medications, and four participants reported reducing or eliminating their sleep medication.”

Overall, 89 participants reported their quality of life had improved over the study period. Two measures changed significantly: patients’ self-rating of sleep quality and pain intensity and interference.

At baseline, the study’s authors calculated respondents’ scores regarding sleep quality to an average of 12.09—the higher the score, the poorer the quality of sleep. At the four-week and eight-week check-in points, the score decreased to 10.7 and 10.3, respectively. Similarly, another scale the authors used to measure pain and how it interferes with the enjoyment of life found the mean score value change from 6.5 at baseline to 5.9 at week 4 and 5.7 at week 8.

“The results of this study suggest that using CBD-rich hemp extract oil may help reduce opioid use and improve quality of life, specifically in regards to pain and sleep, among chronic pain patients,” the study concludes. “This is consistent with emerging literature on the topic, which has concluded that CBD is an effective analgesic, and one that helps reduce barriers to opioid reduction, such as physiological withdrawal symptoms.”

In an interview with Appalachian News Express, the study’s lead author Alex Capano said that outside of survey studies, her research is “the largest study on the use of CBD to reduce the use of opioids in the treatment of chronic pain.”

“It’s also the first study on CBD and opioid reduction to identify key data points, such as hemp extract doses, delivery method, and specific cannabinoid content,” she continued. “Most participants used a relatively low dose of 30mg of CBD per day, whereas other studies on CBD have tested very large doses, 10x or 20x that amount. Lower doses of CBD mean reduced risk of side effects and improved outcomes.”

Bees Like Big Hemp And They Cannot Lie, Study Shows

Published

on

Some pollinators tend to flock to hemp, but according to a recent study, the taller the trees, the more plentiful the bees.

Researchers at Cornell University collected bees at 11 hemp farms in the Finger Lakes region of central New York in the summer of 2018 to identify which ones are attracted to hemp and “to analyze the effects of landscape composition” when they visit the crop.

In the study, published in the journal Environmental Entomology last week, the team found that plant height is “strongly correlated” with bee abundance and that hemp plants at least two meters tall attract “nearly 17 times the number of [bee] visits compared to short plants.”

Both the sheer number and species of bees found visiting hemp “increased with plant height.”

Additionally, they found that the cash crop can support 16 different bee varieties in the northeastern United States.

Of the 355 individual bees captured by “repeated sweep net collections,” 60 percent were Apis mellifera, or western honey bees, while 30 percent were Bombus impatiens, the most commonly encountered bumblebee in eastern North America, which “is intensively relied upon” for pollination, the authors note.

“As cultivation of hemp increases, growers, land managers, and policy makers should consider its value in supporting bee communities and take its attractiveness to bees into account when developing pest management strategies,” they wrote.

“Plant height…was strongly correlated with bee species richness and abundance for hemp plots with taller varieties attracting a broader diversity of bee species.”

A similar study published earlier this year in Colorado concluded that bees are uniquely attracted to hemp, a finding that may inform more sustainable agricultural practices.

Although hemp does not have the characteristic vivid colors, enticing aromas and other alluring features that tempt insects and other pollinators, it nevertheless produces large amounts of pollen at a time of the year when there’s typically a shortage—meaning hemp can be an important and plentiful source of food and nectar for bees when they need it.

The authors noted that bee populations—wild and domesticated alike—have taken a hit in recent years due to “large scale, intensified agriculture.” According to the study, “landscape simplification,” or the replacement of native plants with cash crops, “negatively impacted” the total number of bees near hemp, but did not affect the number of species found. This research suggests that hemp, especially tall plants, could be crucial to stemming declining bee populations.

New York has taken significant steps to encourage the cultivation of hemp. In 2015, the Empire State launched a hemp agricultural research pilot program. Two years later, the state lifted limits on the number of sites authorized for hemp growth and research and expanded the program to include businesses and farmers.

Congress paved the way for a massive expansion of hemp production in 2018 after Senate Majority Leader Mitch McConnell (R) pushed to add a provision legalizing hemp into the 2018 Farm Bill, helping to make his home state of Kentucky a significant hemp producer.

Senate Minority Leader Chuck Schumer (D-NY) has also been a champion of the hemp industry, and he’s taken steps to ensure that his state reaps the benefits of the crop’s legalization. After the Farm Bill was enacted, Schumer celebrated an announcement from a major cannabis company that said it would be investing millions into a hemp park in New York.

And after that company, Canopy Growth Corp., experienced a staffing shakeup, he called executives directly to confirm that plans were still on to launch the site.

People Are Skipping Sleep Aids In Favor of Marijuana, Study Reports

Published

on

The scientific community is still unclear on whether or not marijuana can actually help treat sleep disturbances such as insomnia. A new study, however, found that fewer people purchase over-the-counter (OTC) sleep medications when they have legal access to cannabis.

“Our results show that the market share growth for sleep aids shrank with the entry of recreational cannabis dispensaries by more than 200% relative to the mean market share growth in our sample, and the strength of the association increased with each subsequent dispensary,” the paper, published in the December edition of Complementary Therapies in Medicine, concludes. “In particular, cannabis appears to compete favorably with OTC sleep aids, especially those containing diphenhydramine and doxylamine, which constitute 87.4% of the market for OTC sleep aids.”

“Recreational cannabis dispensaries greatly increase the number of individuals able to legally treat sleep disorders using cannabis, particularly those with mild to moderate sleep disorders.”

Researchers at the University of New Mexico and California State Polytechnic University used retail scanner data collected by the Nielsen Company to help them understand how access to recreational marijuana affected the sales of OTC sleep medications purchased at local stores in Colorado.

In their analysis, they studied the market shares of overall sleep aids—including supplements such as melatonin and pharmaceuticals such as diphenhydramine—at 587 stores. They also used monthly data from the Colorado Department of Revenue to compare the number of recreational dispensaries in each county as well as local cannabis retail sales figures.

“The negative association between cannabis access and sleep aid sales suggests a consumer preference for cannabis.”

It became legal for Colorado residents to purchase cannabis for adult use on January 1, 2014, and the study period covered December 2013 through December 2014.

According to the results, the market share for sleep aids was neither rising nor declining prior to a dispensary opening in the same county. After one did, however, the market share declined with each month of its existence. A regression model showed that sleep aid market share growth decreased by 236 percent after a dispensary entered the market, and this negative association increased as the number of dispensaries grew.

“The magnitude of the market share decline increases as more dispensaries enter a county and with higher county-level cannabis sales.”

“For the first time, we show a statistically significant negative association between recreational access to cannabis and OTC sleep aid sales, suggesting that at least some recreational purchasers are using cannabis for therapeutic rather than recreational purposes,” the study’s authors write.

“Additionally, despite a lack of direct clinical evidence on the effectiveness of self-managed cannabis as a sleep aid, our results indicate that enough individuals are switching from OTC sleep aids to recreational cannabis that we can identify a statistically significant reduction in the market share growth of OTC sleep aids in conjunction with access to recreational cannabis using a statistically conservative county-month-level treatment variable and a quasi-experimental research design,” the paper concluded.

“Our results are consistent with evidence that legal access to medical cannabis is associated with reductions in Scheduled II-V prescription medications (e.g., opioids and sedatives), many of which may be used in part as sleep aids,” the authors wrote.

“These findings support survey evidence that many individuals use cannabis to treat insomnia, although sleep disturbances are not a specific qualifying condition under any U.S. state-level medical cannabis law.”

Study author Sarah Stith, an applied microeconomist at the University of New Mexico, explained in a statement: “From a public health perspective, the possible widespread use of cannabis for less severe medical conditions both highlights its therapeutic potential and raises concerns regarding the risk-benefit tradeoffs of substituting a substance associated with abuse and dependence for relatively ineffective OTC medications with typically low levels of abuse potential.”

“From an economic or business perspective, regardless of underlying mechanism, our documentation of changing purchase behaviors has implications for multimillion-dollar US markets with OTC sleep aids likely just one example,” she said. “It is important for the medical community to recognize that the lack of medical guidance does not necessarily lead to a lack of medical use. Dispensaries and online forums are stepping up to fill the information vacuum as individuals are forced to take treatment into their own hands, with statistically evident effects on treatment choices.”

Scientist Talks Benefits Of Psychedelics At Federal Health Agency Event

Published

on

A federal health agency hosted a leading psychedelics researcher on Tuesday for an event focused on the therapeutic potential of controlled substances such as psilocybin and DMT.

Roland Griffiths, who has spent decades studying various entheogenic plants and fungi, described the existing scientific literature and future research objectives during a speech organized by the National Institute of Mental Health (NIMH). The event was part of NIMH’s “Innovation Speaker” series.

The discussion, titled “Psilocybin: History, Neuropharmacology, and Implications for Therapeutics,” went over studies on the impact of psychedelics on mental health conditions such as depression and substance misuse, the subjective experience of individuals who’ve used such substances for recreational or spiritual purposes and the need for additional research into potential medical applications for psychedelics.

For example, Griffiths presented a slide on the “phenomenological dimensions of mystical experience” elicited from psychedelics. People reported a greater sense of unity, sacredness, “universal love” and “transcendence of time and space,” among other feelings.

He also explained how research has shown that the medically supervised administration of moderate to high doses of psilocybin, the main psychoactive ingredient in so-called magic mushrooms, “can produce substantial and enduring decreases in depressive mood.”

When he was later asked about the risks of psilocybin, Griffiths said the compound is “pretty benign physiologically” and that relatively rare side effects such as increased blood pressure and nausea are often secondary effects attributable to anxiety.

Throughout the presentation, the researcher, who heads Johns Hopkins University’s newly launched Center for Psychedelic Research, stressed the need for further studies, stating that if there’s “opportunity to do any level of analysis” on psychedelics, it should be pursued.

He also offered a preview of one area of focus his research center will be exploring: microdosing. While much of the existing research has focused on the impacts of full doses of psychedelics, he said his team will be exploring how taking smaller doses on a more regular basis can affect mental health and wellbeing.

In his final slide, Griffiths talked about other areas of research that should be investigated. That includes answering questions about how factors such as genetics and personality “affect the likelihood” of having positive responses to psychedelics, what kind of “structural and functional changes in the brain can account for the acute and enduring effects of such experiences,” what behavioral mechanisms are behind those changes and what therapeutic applications can be developed based on the data.

Via NIMH.

While federal agencies have largely avoided broad drug policy reform issues, there seems to be growing willingness to entertain conversations about psychedelics, as a decriminalization movement spreads nationwide.

For example, the heads of the Food and Drug Administration and NIH wrote a letter to a senator in June where they described the status of research into psychedelics such as psilocybin, LSD and ibogaine, which they said present an “opportunity to provide treatment to patients while expanding psychotherapy treatment options.”
