People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detoxification 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 frequently include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to guarantee that any issues are resolved as quickly and safely as possible.
