A survey of drug use among probationers in the Los Angeles area in 1976.
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.
