People who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and present medical supervision for people who are just coming off of drugs. Detox services usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular 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 type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detoxification services, the client will have detox staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
