Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as required to make the detoxification 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 detoxification 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 issues are fixed as swiftly and safely as possible.
