B.C. patients with opioid use disorder who tested positive for THC had reduced fentanyl exposure risk

A study out of B.C. involving people undergoing opioid agonist therapy (OAT) for opioid use disorder (OUD) found that cannabis use was associated with lower exposures to potentially deadly fentanyl. The finding is based on data drawn from two community-recruited prospective cohorts of people who use drugs in Vancouver, notes the abstract of the study, published this month in Drug and Alcohol Dependence . Because there is limited data on how cannabis may affect illicit opioid consumption, particularly fentanyl, researchers sought to better understand the relationship between cannabis use and recent fentanyl exposure. They used urine testing among the participants in OAT, the primary treatment for OUD, between 2016 and 2018.

At the initial interview, fentanyl was detected in the tests of slightly more than half, 53 per cent, of participants. Fentanyl was not as prevalent for those people who tested positive for THC. “Overall study interviews, cannabis use was independently associated with reduced likelihood of being recently exposed to fentanyl,” states the abstract. That risk was called “significantly lower.” Authors point out “the ongoing opioid overdose crisis is driven largely by exposure to illicitly manufactured fentanyl.” That being the case, they say the findings “reinforce the need for experimental trials to investigate the potential benefits and risks of controlled cannabinoid administration for people on OAT.” Exploring the link, if any, between weed and opioids, both legal and illegal, is attracting attention.
