Conformity-commitment, which affected drinking and drug use in a sample of over 1000 teen-agers, was influenced in 13- and 14-year-olds by parents and religion, in 15- and 16-year-olds by peers and religion, and in 17- and 18-year-olds by parents, peers and religion. Religiousness also affected alcohol use directly among all three age groups and cannabis use among 15- and 16-year-olds and 17- and 18-year olds.
