In 387 adolescents followed over time, social and home environment factors predicted substance initiation differently for alcohol vs. cannabis, with family history of addiction moderating these effects.
Parents, school counselors, prevention program designers, and researchers studying adolescent substance use trajectories.
What the researchers found
Protective and risk factors for first substance use were not universal — they differed between alcohol and cannabis initiation, and family history of substance use disorder moderated which environmental factors mattered most.
Why it matters
Prevention programs often treat all substance initiation the same. This study shows that different factors predict alcohol vs. cannabis initiation, suggesting prevention efforts should be tailored rather than generic.
The numbers in context
387 adolescents followed longitudinally, examining alcohol use initiation (AUI) and cannabis use initiation (CUI) separately.
How the study worked
Longitudinal cohort study following 387 adolescents, examining social and local-home environmental predictors of alcohol and cannabis use initiation, with family history of SUD as a moderating variable.
What this study cannot tell us
Moderate sample size of 387. Specific demographic composition may limit generalizability. Self-reported substance initiation may be subject to recall or social desirability bias.
How to read the evidence
Longitudinal design with appropriate moderator analysis — stronger than cross-sectional but moderate sample limits statistical power.
When this study was published
Recent longitudinal analysis addressing the important distinction between alcohol and cannabis initiation pathways in youth.
The bigger picture
One-size-fits-all substance prevention rarely works. Understanding which specific environmental factors drive cannabis vs. alcohol initiation — and how family history changes the equation — can make prevention more effective.
Questions still open
- Should schools implement separate prevention strategies for alcohol vs. cannabis? How can family history be incorporated into targeted prevention without stigmatizing youth?
Common questions
Do the same factors predict alcohol and cannabis use in teens?
Does having a family history of addiction increase risk?
