Two More Studies Show Patients Are Replacing Prescription Painkillers With Marijuana

Published

on

Two new studies out this month offer additional evidence that chronic pain patients are skipping addictive pharmaceuticals and using marijuana instead to help them find relief.

The findings are just the latest in an ever-growing body of research revealing cannabis’s potential to help address the country’s opioid crisis.

The first study, published in the International Journal of Drug Policy, aimed to investigate whether it’s “plausible” that people are substituting marijuana for opioids to help them with pain. Researchers from Florida International University used data from the National Survey on Drug Use and Health to evaluate whether people who live in states where medical cannabis is legal were less likely to turn to opioids for pain relief than those who lived in states where medical marijuana was not an option.

The researchers focused on several variables: whether respondents used or misused any prescription pain relievers during the past year, what states they lived in and whether those states had legalized cannabis for medicinal purposes, among other factors. The responses of 120,764 participants were analyzed for the years 2015 through 2017 of the survey.

According to the authors, “the results generated from the multivariate logistic regression equations show that [medical marijuana laws] are associated with a lower likelihood of opioid pain reliever use, but not misuse.”

“Results provide evidence that MMLs may be effective at reducing opioid reliance as survey respondents living in states with medical cannabis legislation are much less apt to report using opioid analgesics than people living in states without such laws, net other factors.”

These results, the study states, support other research that shows patients prefer to consume medical marijuana over opioids.

“In addition, cannabis enabled patients to reduce their reliance on opioids with a significant proportion indicating that cannabis was equal to opioids for pain relief and preferring cannabis over opioids if it were an available alternative,” it concludes. “Such subjective appraisals by patients are important in this context as the success of a treatment plan is in part determined by the patient’s perceptions of treatment efficacy and tolerance of side effects.”

The second study, published in PLoS ONE, took the question of whether or not patients substituted marijuana for prescription painkillers directly to the people. In a nationally representative survey of 16,280 adults, researchers from the San Francisco Veterans Affairs Medical Center asked participants to share information about their opioid and marijuana use. They also asked if they’d noticed a change in the amount of opiate medications they needed for pain because of marijuana use, and why patients who substituted cannabis for their prescription pain killers did so.

More than half of the people queried responded to the survey. Of the 9,003 respondents, 486 (5 percent) reported using marijuana and opioids in the past year; 43 percent said they took opioids daily and 23 percent reported consuming marijuana within the past month.

According to the study’s findings, 41 percent of that sample decreased or stopped using opioids because of marijuana use, while 46 percent reported no change in opioid use and 8 percent said they increased their opioid intake.

“We found that a substantial number of US adults reported that they substituted marijuana for opioids.”

“The most commonly reported reasons for substitution were better pain management (36%) and fewer side effects (32%) and withdrawal symptoms (26%), compared to the non-medical reasons for use: cheaper (13%) and more social acceptance from marijuana use (13%),” the study’s authors write.

“More research on this topic is clearly needed,” the study states. “Nonetheless, our findings suggest that even if objective measures do not support that marijuana is substitutive for opioid use, patients perceive that marijuana use has reduced their opioid use. Perhaps the commercialization of marijuana and the favorable media coverage surrounding the health effects of marijuana are fostering such a perception.”

Ultimately, both studies reveal the importance of patient-centered care in efforts to mitigate opioid use and misuse. That’s exactly what the Department of Health & Human Services (HHS) Pain Management Inter-Agency Task Force called for earlier this year.

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.”

Problematic Marijuana Use Is Declining Among People Who Consume Every Day, Study Finds

Published

on

Contrary to the expectations of public health experts, the rate of frequent marijuana consumers who are diagnosed with cannabis use disorder (CUD) is not increasing, a new study reports. In fact, it’s actually decreasing, and that may be due to the growing number of states that have legalized access to marijuana.

According to the paper, “CUD prevalence decreased significantly across all ages reporting daily/almost daily cannabis use between 2002-2016. Cannabis dependence prevalence decreased for adolescents and young adults and was stable only among adults ages 26+ reporting daily/almost daily cannabis use.”

Recent studies have had mixed results on the prevalence of CUD—a diagnosis that includes either misuse and/or dependence—in the last two decades. Because people who consume marijuana every day or almost every day are the most at risk for problematic use, researchers at Columbia University’s Mailman School of Public Health set out to get a better understanding of this group’s general health.

Their findings were published last month in the journal Drug and Alcohol Dependence.

The study’s authors used data from the National Surveys on Drug Use and Health for the years 2002-2016. The final sample, totaling 22,651 people, included participants who were 12 and older and reported using marijuana at least 300 days in the past year.

To measure problematic marijuana use, the authors used criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, for cannabis dependence and cannabis abuse, such as:

  • Spent a great deal of time over a period of a month obtaining, using, or getting over the effects of marijuana
  • Unable to keep set limits
  • Unable to cut down cannabis use
  • Recurrent use resulting in failure to fulfill major role obligations
  • Continued use despite persistent or recurrent social or interpersonal problems

Other factors considered in the research asked whether participants had a perceived need for mental health treatment, whether a doctor had indicated they had other health issues and whether or not they’d driven under the influence of illegal drugs with and without alcohol.

Over the study period, the authors found that the prevalence of CUD decreased among their sample in all age groups: For adolescents ages 12 to 17, the rate fell by 26.8 percent; for 18- to 25-year-olds, by 29.7 percent; and for adults 26 and older, by 37.5 percent.

“Among those with past-year daily/almost daily cannabis use, there were reductions in the prevalence of DSM-IV cannabis abuse across all age groups, with reductions observed for all individual abuse items in adolescents and young adults,” the study states. “There were also reductions in the prevalence of DSM-IV cannabis dependence among adolescents and young adults, but not in adults ages 26+. Reductions in most DSM-IV dependence items were observed in young adults while reductions in only a few dependence items were found for adolescents and older adults.”

Researchers offer several possible explanations for the declining rates, many of which point to the influence of legalization. “First, the new national cannabis policy environment, with 33 states legalizing medical use and 10 states allowing recreational use of cannabis may have played a role in reducing stigma and perceptions of risk associated with cannabis use,” Silvia Martins, one of the study’s authors, said in a statement. “Secondly, increasing legalization may also be associated with changes in social attitudes resulting in fewer conflicts with relatives and friends around cannabis use.”

As a result, according to the paper, “[t]his could explain reductions in the abuse item ‘Continued use despite persistent or recurrent social or interpersonal problems,’ which reflects difficulties in interactions with others due to cannabis use.”

It’s also possible that “a sector of the population that is healthier overall” is starting to use marijuana more because of legal access, which “may have diluted the prevalence of cannabis abuse/dependence over time.” They may use “less potent” cannabis or in lower daily amounts, researchers note. Additionally, more people may feel less afraid to admit on a federal survey that they use marijuana frequently.

Ultimately, Martins said, the study’s results “contradict the predominating hypothesis that the prevalence of DSM-IV CUD would be stable, or increase, among those using with this regularity.”

Marijuana Use Tied To Lower Rates Of Depression And Suicidal Ideation Among PTSD Patients

Published

on

People suffering from post-traumatic stress disorder (PTSD) who consume marijuana experience significantly fewer depressive episodes and lower rates of suicidal ideation compared to non-users, according to a new study.

The research, published in the Journal of Psychopharmacology on Tuesday, analyzed nationally representative health data from Statistics Canada’s 2012 Community Health Survey and found that people with PTSD who have not reported past-year marijuana use are much more likely to have suicidal thoughts and go through depressive phases.

“This study provides preliminary epidemiological evidence that cannabis use may contribute to reducing the association between post-traumatic stress disorder and severe depressive and suicidal states.”

Among the more than 24,000 people who were eligible for the study, with was conducted by researchers at the the British Columbia Centre on Substance Use and University of British Columbia, 420 were clinically diagnosed with PTSD. Of those, 106 individuals with PTSD (28.2 percent) said they used cannabis in the past year. That’s markedly higher than the average of those who don’t have PTSD (11.2 percent).

“We know that with limited treatment options for PTSD, many patients have taken to medicating with cannabis to alleviate their symptoms,” Stephanie Lake, lead author of the study, said in a press release. “However, this is the first time that results from a nationally representative survey have shown the potential benefits of treating the disorder with cannabis.”

Those suffering from PTSD who didn’t report past-year cannabis use were about seven times as likely to have experienced a recent major depressive episode, the study found. They were also 4.3 times as likely to have contemplated suicide.

“Among cannabis-using respondents, PTSD was not associated with a recent depressive episode or suicide ideation.”

While the study only looked at Canadian respondents, the findings are relevant to U.S. patients as well, as members of the military stateside also experience higher rates of PTSD compared to the general population.

A former secretary of the U.S. Department of Veterans Affairs (VA), David Shulkin, has said recently that he’s in favor of having the department conduct clinical research into the therapeutic benefits of marijuana for veterans with PTSD, stating that the suicide rate among the population demonstrates that ignoring the treatment option comes at the “peril” of service members.

While VA declined to support research initiatives into cannabis for medical conditions that commonly afflict veterans under his leadership, Shulkin said this week that the department “should be involved and should be open to research for anything that will help veterans improve their lives, including medical cannabis.”

“We’re only just beginning to understand what the therapeutic potential of cannabis may be for a variety of health conditions,” M-J Milloy, senior author of the new study, said. “These findings are promising, and merit further study in order to fully understand the benefits of cannabis for people living with PTSD.”
