Individuals who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can properly oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detox services, the client will have detox staff at their disposal around the clock to assure that any difficulties are resolved as rapidly and safely as possible.
