Highlighted in bold is p ≤ 0.05. A logistic regression was run with adjustments for socio-economic status, parental migration background, education level, sensation-seeking, low self-control, internalizing symptoms, bullying, leisure activities, exposure to friends’ substance use, and self-reported subjective stress.
^aDue to collinearity of own substance use and exposure to a friends' substance use, only those observations that have exposure to friends' substance use were examined
