Impact of baseline methamphetamine/amphetamine use on discontinuation of methadone and buprenorphine/naloxone among people with prescription‐type opioid use disorder in Canada

Although concurrent stimulant use is common among people with opioid use disorder (OUD), there is little evidence on its impacts on opioid agonist therapy (OAT) outcomes. This study sought to determine the impact of baseline methamphetamine/amphetamine use on discontinuation of OAT among individuals with prescription-type OUD (POUD) initiating methadone or buprenorphine/naloxone as part of a pragmatic randomized trial in Canada.
