Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can appropriately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as wanted to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to make sure that any complications are resolved as quickly and safely as possible.
