Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the individual is as comfortable 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 needed to make the detox process as smooth and safe as possible. The individual in detox 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 treatment facility which can offer detox services, the client will have detox staff at their disposal around the clock to make sure that any issues are resolved as rapidly and safely as possible.
