Associations between past-year frequency of cannabis vaping and cannabis-related problems among past-year cannabis users. RRs refer to frequency of cannabis vaping before (Model 1) and after (Models 2–4) sequentially controlling for covariates.

Note. N = 349 because 8 participants were missing data on one or more covariates. RR = risk ratio. SE = standard error. MACQ = Marijuana Consequences Questionnaire. Statistically significant associations are shown in bold. Response options for frequency of cannabis use, cannabis vaping, edible use, binge drinking, and drug use were: no use in the past year (scored ‘0’), <5 times (scored ‘1’), >5 times but less than once a month (scored ‘2’), about once a month (scored ‘3’), once a week (scored ‘4’), a couple times a week (scored ‘5’), nearly every day (scored ‘6’), and more than once a day (scored ‘7’).
