ABSTRACT
Percent means per one hundred. For instance, say there are 100 residents in a town and 60" are left-handed. This means 60 per one hundred are left-handed, or 60 in total are left-handed. Now, you do not have to have a group size of 100 to use the idea of percent. The adolescent clients within three sites of a drug-free residential treatment community (TC) were surveyed. Daytop Village has a network of adolescent treatment programs located in upstate New York (Adolescent Diagnostic Unit, Foxrun, and Millbrook) that utilize a modified TC approach. The questionnaire used in this study consisted of 102 questions and was divided into four sections. The third section inquired about past drug use, including lifetime history and perceived greatest problem drug. The youths were queried as to greatest problem drug among 12 substances (marijuana, hallucinogens, alcohol, benzodiazepines, depressants, noncocaine stimulants, cocaine, heroin, prescription opiates, inhalants, "club drugs", and nicotine).
