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.”
