title: Drug use among 8th grade students is increasing.
abstract: Among United States 8th grade students, marijuana and stimulant use declined from 1987 to 1990. Since then, marijuana and inhalant use have increased. Before 1989, marijuana was the most frequently tried drug by 8th graders. Since then, more students have tried inhalants than have tried marijuana.
