Individuals who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as required 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 detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any difficulties are resolved as swiftly and safely as possible.
