A Drug Treatment and Testing Order (DTTO) is a criminal justice measure aimed at individuals aged 18 and over who have been convicted of a serious offence and have a proven drug misuse problem. It is an alternative to a custodial sentence and is used in England and Wales. The order requires the offender to undertake treatment and rehabilitation for their drug misuse, as well as drug testing and other requirements such as attending court, engaging with probation services, or attending appointments with healthcare professionals. The aim is to reduce the offender’s reliance on drugs and to reduce their risk of reoffending. The order is subject to regular reviews and can last for up to two years. It is monitored by the courts and probation services, and any breach of the order can result in the offender being recalled to court. The DTTO is a key part of the UK housing policy, providing an effective way to reduce drug-related crime, helping to create safer and healthier communities.
