Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and present medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is receiving proper rest, and providing 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 kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detoxification services, the individual will have detoxification staff at their disposal around the clock to make certain that any problems are fixed as rapidly and safely as possible.
