Men and women who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving 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 carry 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 detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification 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 individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some variety 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 complications are fixed as rapidly and safely as possible.
