DTTOs are a sentencing option for magistrates dealing with persistent offenders of drug-related crimes. A DTTO can be made, with the agreement of the offender, to last from three months to three years. The order requires the offender to undergo treatment to address their drug use and reduce offending. Random urine tests are taken two or three times a week to ensure compliance. Detection of any illicit substances in the offenders system may lead to a breach of the order with the offender being sent back to court for further sentencing.
