Drug use of friends: a comparison of reservation and non-reservation Indian youth.

There is not much drug use at school, but reservation youth are most likely, non-reservation Indian youth next most likely, and non-Indian youth least likely to have used drugs at school. Alcohol and drugs are used most frequently at weekend parties and at night with friends. Reservation youth are twice as likely as the others to have used alcohol while driving around and three times more likely to have used drugs while driving around. Drugs are used with friends. Heavy drug users are more likely to have friends who use drugs and friends who encourage drug use and are less likely to have friends who would try to stop them from using drugs.
