N = 1,244; N for past-year vaping analyses is reduced because questions asked of only a randomly selected subsample (n = 811).
p-values for differences are from logistic regression models with multiple imputed data that included only bivariate associations of each variable and each substance use outcome.
Bolded relationships are statistically significant (p < .05).
Current student indicated current full-time student in a 4-year college/university (vs. other); parental education indicates one parent has a college degree (vs. other).
CI = confidence interval.
Measured using the following question: “How much has the COVID-19 situation made you feel isolated or alone?”
Measured using the following question: “How much has social distancing caused stress for you?”
