The use of cannabis by patients enrolled in a methadone maintenance treatment program is associated with fewer nonfatal opioid overdoses, according to the results of a recently published study. An abstract of the research, “Cannabis Use and Nonfatal Opioid Overdose among Patients Enrolled in Methadone Maintenance Treatment,” was published online last month by the journal Substance Use & Misuse.
