Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is frequently uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to make sure that any complications are fixed as quickly and safely as possible.
