Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as necessary to make the detox 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 detoxification facility or drug rehab facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to ensure that any complications are fixed as swiftly and safely as possible.
