Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services usually 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 detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to make sure that any complications are handled as swiftly and safely as possible.
