Alcohol and cannabis motives: differences in daily motive endorsement on alcohol, cannabis, and alcohol/cannabis co-use days in a cannabis-using sample

摘要

Objective: Same day use of alcohol and cannabis is prevalent among emerging/young adults and increases the risk for negative consequences. Although motives for alcohol and cannabis use are well-documented, specific motives on co-use days are under-investigated. We examined differences in motives on single substance use (i.e. alcohol or cannabis) versus co-use days in a sample of primarily cannabis-using emerging/young adults.
