People who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not carried out 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 properly oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services usually 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 getting proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detox services, the person will have detox staff at their disposal around the clock to make certain that any problems are resolved as quickly and safely as possible.
