title: Frequency of use of diazepam in individuals on probation and in methadone maintenance programs.
abstract: During the spring of 1977 a survey was taken of drug analysis results for over 17,500 urine samples from Los Angeles County probationers and over 8,500 urine samples from Los Angeles County methadone clinic enrollees to determine the frequency of diazepam (Valium) use. The probation department specimens were found to contain diazepan less frequently than the methadone clinic specimens as a group. There were, however, wide variations in use frequency between the seven methadone clinics.
