People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and present medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to make certain that any difficulties are handled as swiftly and safely as possible.
