Individuals who are physically dependent to drugs or alcohol and want help will first 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 frequently uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and present medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the individual 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 necessary to make the detoxification process as smooth and safe as possible. The person in detox 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 rehab facility which can offer detoxification services, the person will have detoxification staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
