Residential short-term treatment for drug or alcohol addiction is a type ofrehabilitation program where the addicted individual will remain at the facility on an inpatient basis, and which typically requires a stay of 30 days or less. While attending residential short-term treatment the client undergoes an intensive but short duration of treatment that typically 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 daily life once rehabilitation is complete. Residential short-term treatment is not always effective for all instances of addiction, and most will require an aftercare program or additional treatment in a more long-term residential facility.
