Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to ensure that any complications are resolved as rapidly and safely as possible.
