People who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not carried out in a setting which can offer 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 provide medical supervision for persons 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, providing proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as required to make the detox process as smooth and safe as possible. The individual 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 supply detoxification services, the individual will have detoxification staff at their disposal around the clock to assure that any complications are resolved as swiftly and safely as possible.
