abstract="Alcohol and other drug problems experienced by adolescents who use only alcohol compared to those who use both alcohol and marijuana (A + M) is studied. Using the national longitudinal survey of youth 1994 data, forward multiple regression analyses revealed that impulsivity, A + M use (compared to alcohol-only use), age, sex, religiosity, frequency of substance use were associated with a higher number of behavioral problems. Youth with more alcohol problems were found to be binge drinkers, impulsive, more frequent alcohol users, and nonHispanic. Implications and future research needs are discussed.<p /><p>Language: en</p>",
