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