Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services frequently include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The 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 treatment facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to guarantee that any complications are fixed as quickly and safely as possible.
