title: Sequences of drug involvement in African-American and Puerto Rican adolescents.
abstract: This study examined stages in drug involvement of 695 African-American and 637 Puerto Rican adolescents. Analysis indicated that adolescents progress through several stages of drug involvement: beer/wine, cigarettes or hard liquor, then marijuana, and, finally, illicit drugs other than marijuana. The sequence of drug involvement for both ethnic groups appears to be both unidimensional and cumulative.
