People who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and provide medical supervision for people who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as wanted 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 type of physical activity such as walking, yoga, etc. At a drug detox 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 problems are resolved as rapidly and safely as possible.
