Residential short-term treatment for drug or alcohol addiction is a type ofrehabilitation program where the person will remain at the facility on an inpatient basis, and which usually 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 usually incorporates a supervised detox, counseling, and other forms of therapy which are aimed at helping the person become rehabilitated and able to function without drugs in everyday life once rehabilitation is complete. Residential short-term treatment is not always effective for all instances of addiction, and most will need an aftercare program or further treatment in a more long-term residential facility.
