KEY POINTS • Despite the common practice of drug testing as a condition of supervision, there is no research that focuses on the effectiveness of drug testing on its own in reducing recidivism and drug use. • Increased drug testing as part of an Intensive Supervision Program (ISP) approach does not reduce re-offending but does increase the detection of technical violations and revocations. • Random drug testing alongside swift, certain, and fair sanctions shows evidence for reducing recidivism and drug use in the short-term but shows no benefit once the individual goes back to supervision as usual. • Drug testing works well as a way to monitor compliance with supervision conditions, but there is no evidence that it reduces re-offending or drug use when used apart from other supervision practices.
