Residential short-term treatment for drug or alcohol addiction is a type ofrehabilitation program where the individual will stay at the facility on an inpatient basis, and which normally requires a stay of 30 days or less. While in residential short-term treatment the person undergoes an intensive but brief course of treatment that commonly incorporates a supervised detox, counseling, and other forms of therapy which are aimed at helping the individual become rehabilitated and able to function without drugs in everyday life once treatment is complete. Residential short-term treatment is not always effective for all instances of addiction, and most will require an aftercare program or further treatment in a more long-term residential setting.
