An Empirical Approach to a Standard Practice: Drug Testing.

Drug testing is a common practice for community supervision in the U.S., despite limited research on its effectiveness at deterring future drug use. The present study explores the purpose of drug testing by examining the relationship between drug test frequency and positive test results. The impact of the type of drug tested (any vs. serious) and the risk and need level of the individuals tested are also examined. Results indicate that after controlling for risk and substance abuse need, more frequent testing schedules are associated with an increased rate of positive drug tests, suggesting more frequent testing detects rather than deters drug use. Policy implications for community corrections' purpose and use of drug testing are discussed. [ABSTRACT FROM AUTHOR]
