and childhood sexual abuse were not asked at only 4 out of 6 sites due to IRB restrictions and thus not included in analyses; childhood neglect was not assessed. Substance use: Offspring report of ever use of cannabis was included in the model. Perceived substance use of peers was based on respondent report at first interview (for those 18 and older) or at the interview obtained closest to age 17 (for those under 18 at baseline) that “most” or “all” peers (best friends, romantic partners and schoolmates) from ages 12-17 used any substance (tobacco, alcohol, cannabis or other drugs). High correlations (r's > 0.8) precluded substance-specific estimates.
