Men and women who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detox services frequently include insuring the individual 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 providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detox services, the individual will have detox staff at their disposal around the clock to assure that any difficulties are fixed as quickly and safely as possible.
