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. Detox is basically the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The person in detox 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 rehabilitation facility which can supply detox services, the client will have detox staff at their disposal around the clock to assure that any complications are fixed as quickly and safely as possible.
