The DATC program is operated by the Correctional Services Department. The program provides residential treatment for convicted drug addicts, as it provides the courts with an alternative to sending a drug addict to prison. The program aims at enabling drug addicts to lead a drug-free and useful life. The three phases of the program focus on restoring physical health, eliminating psychological and emotional dependence on drugs, and reintegration into the community.
