Altered States in the Palmetto State: Statistical Indicators of Illegal Drug Use is designed to provide information about the nature and extent of illegal drug use in South Carolina. The intent is to provide empirical indicators for a problem which is too often described on the basis of perception and anecdotal data, in a straightforward, non-technical manner. Hopefully this report will serve to better inform citizens, policy makers and others about the nature and extent of illegal drug use in our state.
