Individuals 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 basically the procedure of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can appropriately oversee and present medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is getting proper rest, and supplying supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any complications are fixed as swiftly and safely as possible.
