People who are physically reliant to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is often uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and supply medical supervision for people who are just coming off of drugs. Detox services usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The individual 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 treatment facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make certain that any complications are handled as rapidly and safely as possible.
