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 procedure of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and supply 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, offering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The particular person in detoxification 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 treatment facility which can provide detoxification services, the individual will have detox staff at their disposal around the clock to assure that any difficulties are fixed as rapidly and safely as possible.
