More than two-thirds of chronic pain patients registered to legally access medical cannabis products substitute marijuana for prescription opioids, according to data published in The Journal of Headache and Pain.
Investigators from the United States and Canada assessed the use of medical cannabis and prescription drugs in a cohort of over 2,000 Canadian patients licensed to access marijuana products. Among those patients with a primary diagnosis of chronic pain, 73 percent reported substituting cannabis in place of opioids. Among those patients diagnosed specifically with headache/migraine, cannabis was frequently reported as a substitute for other medications – including opiates (43 percent), anti-depressants (39 percent), NSAIDS (21 percent), triptans (8 percent), and anti-convulsants (8 percent).
“Most patients in the pain groups reported replacing prescription medications with medicinal cannabis, the most common of which were opiates/opioids across all patient groups,” authors concluded. “This is notable given the well-described ‘opioid-sparing effect’ of cannabinoids and growing abundance of literature suggesting that cannabis may help in weaning from these medications and perhaps providing a means of combating the opioid epidemic.”
The study’s findings are consistent with those of numerous others finding that patients in medical cannabis access programs significantly reduce or eventually eliminate their use of opioid analgesics over the long-term.
