People who are physically dependent to drugs or alcohol and want assistance will first 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 offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and present medical supervision for men and women who are just coming off of drugs. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as needed to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any complications are handled as swiftly and safely as possible.
