Religiosity, religious affiliation, and alcohol and drug use among American college students living in Germany.

The influence of religious values and religious affiliation on alcohol and drug use among American college students living in Germany is examined. Religious affiliation differentiates among Protestant, Catholic, and nonaffiliated groups for reported high school alcohol use but not for collegiate alcohol consumption. Groups defined by the importance of religious values differ on reported high school and college alcohol and drug use. Implications for prevention and future research are discussed.
