Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may carry risks if not performed 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 rehab facility which can effectively oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detox services, the client will have detox staff at their disposal around the clock to assure that any issues are fixed as swiftly and safely as possible.
