New data published in the Journal of Pain Research has found adults have been substituting cannabis for their prescription medications. Researchers from Bastyr University Research looked at the frequency of drug substitution from a national sample of 2,774 self-identified marijuana consumers, and found 46% of respondents used cannabis as a substitute of prescription medications. They were most likely to use cannabis instead of opioids/narcotics (36%), followed by anxiolytics/benzodiazepenes (14%), and then antidepressants (13%). The substitution was more prominent among women and older respondents. Additionally, medical marijuana patients were four times more likely than non-medical cannabis users to make this substitution. Authors concluded this study contributes "to a growing body of literature suggesting cannabis, legal or otherwise, is being used as a substitute for prescription drugs, particularly prescription pain relievers."
