Individuals who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is often uncomfortable and may carry risks if not carried out 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 treatment facility which can effectively oversee and provide medical supervision for people who are just coming off of drugs. Detox services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detox services, the client will have detoxification staff at their disposal around the clock to assure that any complications are resolved as rapidly and safely as possible.
