Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services usually include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The particular person 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 supply detoxification services, the person will have detox staff at their disposal around the clock to ensure that any problems are resolved as quickly and safely as possible.
