People who are physically dependent to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as wanted 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 form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make sure that any issues are resolved as swiftly and safely as possible.
