Alcohol remains the single most abused substance by citizens of Maryland. Cocaine is the second most frequently mentioned drug among Maryland treatment admissions. Indicators do not yet identify a major new recruitment to heroin abuse. However, law enforcement intelligence shows that there are more dealers in the state who are actively trying to market heroin and that it is available from a variety of sources. A 3-percent increase in marijuana-related treatment admissions among clients under age 18 is predicted for FY 1993. There are no shortages in availability of synthetic drugs such as PCP and LSD. There are few good indicators of nonmedical use of licit pharmaceuticals.
