Hong Kong adopts a multi-modality approach in providing drug treatment and rehabilitation services to cater for different needs of drug abusers with varying backgrounds and circumstances. As the drug abuse trend and pattern change, these modalities of drug treatment and rehabilitation services have continuously been adjusted and improved to respond to the needs of the latest drug scene. Under the lead of Narcotics Division of the Security Bureau, the Social Welfare Department (SWD) is one of the departments in providing services for drug abusers.

The overall objective of the services is to help the drug abusers to abstain from their drug-taking habits and re-integrate into the community. This is achieved through both community-based and residential services by means of individual and group counselling, vocational training, social skills training and aftercare service, etc.
