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. Detoxification is simply the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and supply medical supervision for people who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy 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 treatment facility which can present detox services, the individual will have detox staff at their disposal around the clock to make certain that any complications are resolved as rapidly and safely as possible.
