People who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification 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 often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as smooth and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detox services, the person will have detox staff at their disposal around the clock to assure that any problems are fixed as rapidly and safely as possible.
