Associations between past-year frequency of cannabis vaping (Panel A) and edible use (Panel B) and driving while high on cannabis (N = 357).

Panel A: Associations between frequency of cannabis vaping and odds of driving while high on cannabis. ORs refer to frequency of cannabis vaping before (Model 1) and after (Models 2–4) sequentially controlling for covariates.
Independent variables	OR	95% CI	p
Model 1: Frequency of Cannabis Vaping	1.67	1.40, 1.99	<0.001
Model 2: Model 1 + Age, Sex, Race, and SES	1.67	1.40, 2.00	<0.001
Model 3: Model 2 + Sensation Seeking, Age of First Cannabis Use
Frequency of Binge Drinking, and Frequency of Drug Use	1.48	1.24, 1.77	<0.001
Model 4: Model 3 + Frequency of Overall Cannabis Use	1.22	1.01, 1.49	0.047

Panel B: Associations between frequency of edible use and odds of driving while high on cannabis. ORs refer to frequency of edible use before (Model 1) and after (Models 2–4) sequentially controlling for covariates.
Independent variables	OR	95% CI	p
Model 1: Frequency of Edible Use	1.96	1.50, 2.58	<0.001
Model 2: Model 1 + Age, Sex, Race, and SES	1.94	1.48, 2.56	<0.001
Model 3: Model 2 + Sensation Seeking, Age of First Cannabis Use
Frequency of Binge Drinking, and Frequency of Drug Use	1.60	1.20, 2.13	0.001
Model 4: Model 3 + Frequency of Overall Cannabis Use	1.19	0.88, 1.61	0.26

Note. N = 349 because 8 participants were missing data on one or more covariates. Statistically significant associations are shown in bold. Race was dummy coded into one of four groups: 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’).
