Veterans consume cannabis at rates far higher than the general population, and many report using it for medical purposes
Among military veterans who acknowledged using cannabis within the past year, 41 percent classified their marijuana use as medical – a percentage that is twice as high as is reported by adults in the general population.
According to nationwide survey data conducted by The American Legion in 2017, 39 percent of respondents affirmed that they "know a veteran" who is using the plant medicinally. Twenty-two percent of respondents said they themselves "use cannabis to treat a mental or physical condition."
Medical marijuana use among veterans would likely be even higher were not VA physicians forbidden under federal law from recommending cannabis therapy in the states that permit it. According to a December 2017 policy guidance update issued by the US Department of Veterans Affairs, doctors may facilitate to discussions with veterans about their cannabis use "due to its clinical relevance to patient care,” but "providers are prohibited from completing forms or registering veterans for participation in state-approved [medical marijuana] program[s]."
Veterans often report using cannabis to treat symptoms of chronic pain and mood disorders, like post-traumatic stress. Clinical data supports the use of cannabis treatment for these indications.
According to a review of over 10,000 studies by the National Academy of Sciences, “In adults with chronic pain, patients who were treated with cannabis … are more likely to experience a clinically significant reduction in pain symptoms. … There is conclusive or substantial evidence that cannabis and cannabinoids are effective for the treatment for chronic pain in adults.”
A retrospective review of PTSD patients' symptoms published in 2014 in the Journal of Psychoactive Drugs reported a greater than 75 percent reduction CAPS (Clinician Administered Posttraumatic Scale) symptom scores following cannabis therapy.
"Cannabis may dampen the strength or emotional impact of traumatic memories through synergistic mechanisms that might make it easier for people with PTSD to rest or sleep and to feel less anxious and less involved with flashback memories. ... Evidence is increasingly accumulating that cannabinoids might play a role in fear extinction and anti-depressive effects."
"Colorado's legalization of recreational cannabis sales and use resulted in a 0.7 deaths per month reduction in opioid-related deaths. This reduction represents a reversal of the upward trend in opioid-related deaths in Colorado."
“States with medical cannabis laws had a 24.8% lower mean annual opioid overdose mortality rate compared with states without medical cannabis laws. Examination of the association between medical cannabis laws and opioid analgesic overdose mortality in each year after implementation of the law showed that such laws were associated with a lower rate of overdose mortality that generally strengthened over time: year 1 (−19.9%), year 2 (−25.2%), year 3 (−23.6%), year 4 (−20.2%), year 5 (−33.7%), and year 6 (−33.3%).”
Studies of pain patients eligible for medical marijuana access find that most subjects significantly reduce or eliminate their use of opioids following cannabis therapy
"Between August 1 - December 31, 2016 a total of 2290 patients were enrolled in the program under the qualifying condition of intractable pain; 45 of these patients were previously enrolled in the program under an additional qualifying condition. This report focuses on the 2245 patients who were certified for intractable pain and enrolled in the program for the first time during this interval. ... A large proportion (58%) of patients on other pain medications when they started taking medical cannabis were able to reduce their use of these meds according to health care practitioner survey results. Opioid medications were reduced for 38% of patients (nearly 60% of these reduced at least one opioid by ≥50%), benzodiazepines were reduced for 3%, and other pain medications were reduced for 22%. If only the 353 patients (60.2%, based on medication list in first Patient Self-Evaluation) known to be taking opioid medications at baseline are included, 62.6% (221/353) were able to reduce or eliminate opioid usage after six months."
"During the study period, 2736 patients above 65 years of age began cannabis treatment and answered the initial questionnaire. The mean age was 74.5 ± 7.5 years. The most common indications for cannabis treatment were pain (66.6%) and cancer (60.8%). After six months of treatment, 93.7% of the respondents reported improvement in their condition and the reported pain level was reduced from a median of 8 on a scale of 0-10 to a median of 4. ... After six months, 18.1% stopped using opioid analgesics or reduced their dose. ... Cannabis use may decrease the use of other prescription medicines, including opioids."
University of New Mexico investigators assessed opioid prescription use patterns over a 21-month period in 37 pain patients enrolled in the state's medicinal cannabis program compared to 29 non-enrolled patients. Compared to non-users, medical cannabis enrollees "were more likely either to reduce daily opioid prescription dosages between the beginning and end of the sample period (83.8 percent versus 44.8 percent) or to cease filling opioid prescriptions altogether (40.5 percent versus 3.4 percent)." Enrollees were also more likely to report an improved quality of life. "The clinically and statistically significant evidence of an association between MCP enrollment and opioid prescription cessation and reductions and improved quality of life warrants further investigations on cannabis as a potential alternative to prescription opioids for treating chronic pain.”
“Among respondents that regularly used opioids, over three-quarters (76.7%) indicated that they reduced their use since they started MC (medical cannabis). … Approximately two-thirds of patients decreased their use of anti-anxiety (71.8%), migraine (66.7%), and sleep (65.2%) medications following MC.”
"Among study participants, medical cannabis use was associated with a 64% decrease in opioid use (n = 118), decreased number and side effects of medications, and an improved quality of life (45%). This study suggests that many CP (chronic pain) patients are essentially substituting medical cannabis for opioids and other medications for CP treatment, and finding the benefit and side effect profile of cannabis to be greater than these other classes of medications."
"The treatment of chronic pain with medicinal cannabis in this open-label, prospective cohort resulted in improved pain and functional outcomes, and a significant reduction in opioid use. ... Opioid consumption at follow-up decreased by 44%."
