People who are physically dependent to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detox services, the client will have detoxification staff at their disposal around the clock to assure that any complications are resolved as rapidly and safely as possible.
