OBJECTIVE: As cannabis products are becoming increasingly available and young adults are increasingly using vaporizers to consume cannabis, there is a need to understand how this population is using different modes of administration and the extent to which specific modes are associated with differential cannabis use outcomes. Toward this end, the current study characterized predictors of cannabis mode of administration and examined how consumption levels and subjective intoxication vary as a function of mode of administration in daily life. METHOD: Participants were 106 young adult cannabis and heavy alcohol users (51% female) who completed up to 14 daily diaries (n = 1,405 person days). Each day, participants reported whether they used any cannabis and, if any, which mode(s) were used, number of hits used per mode, overall subjective intoxication, and the socio-environmental context in which they used cannabis. RESULTS: Across all cannabis use days, Bong-Only and Vape-Only days were the most common, followed by Multimode, Joint-, Pipe-, and Blunt-Only days. Participants reporting a greater proportion of cannabis use days were more likely to report Bong-Only and Multimode days than Vape-Only days. Compared to Vape-Only days, participants reported fewer hits on Bong-Only days and more hits on Blunt-Only, Pipe-Only, and Multimode days. Participants felt more intoxicated on Bong-Only days than Vape-Only days. CONCLUSIONS: Mode-specific associations with cannabis consumption and subjective intoxication levels suggest assessing modes of administration may be a meaningful way to guide individual and public health intervention efforts.
