Note: High-risk drinking, men: >4 drinks/day or >14 drinks/week; women: >3 drinks/day or >7 drinks/week; Low-risk drinking = drinking below high-risk levels.

log-transformed for regression;

inestimable due to zero cell;

drug use=lifetime use 11 or more times of marijuana, cocaine, stimulants, sedatives, opiates, PCP, hallucinogens, solvents, combination or other illicit drugs; drug use history = most recent drug use at least one year ago;

nicotine habitual use (20 cigarettes or more daily for at least 6 months) was used in wave 1 data, since nicotine dependence added late in wave 1 and thus was not available for all participants;

Significance tests conducted using multinomial logistic regression with AUD as reference category and robust variance estimator to correct for clustering of family data.
