In 2001, 10th graders in Frederick County were involved in the current use of marijuana, LSD, PCP, methamphetamines, designer drugs, heroin, amphetamines, barbiturates, and narcotics at higher levels than among 12th graders; however, this may reflect the high dropout rates for high school seniors in the county.
