title: A survey of drug use among probationers in the Los Angeles area in 1976.
abstract: The results are presented from the analysis of 10,000 urine specimens from Los Angeles County probationers in early 1976 for the following drugs: amphetamine, methamphetamine, allylbarbital, amobarbital, butabarbital, pentobarbital, phenobarbital, secobarbital, morphine, codeine, methadone, primary metabolite of methadone, cocaine, benzoylecgonine, propoxyphene, norpropoxyphene, methaqualone, and phencyclidine. Over 27% of the urine samples analyzed were positive for at least one drug. Opiates were found to be the most widely used drugs, but multiple drug use was also quite common.
