“Clinical, experimental, and ethnographic research suggests that cannabis may be used to help manage pain.
Ethnographic research has revealed that some people are using cannabis to temper their illicit opioid use. We seek to learn if there is an association between cannabis use and the frequency of nonmedical opioid use among people who inject drugs (PWID).
…people who used cannabis used opioids less often than those who did not use cannabis…
There is a statistical association between recent cannabis use and lower frequency of nonmedical opioid use among PWID.
This may suggest that PWID use cannabis to reduce their pain and/or nonmedical use of opioids.”
