People who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services frequently include insuring the client is as comfortable 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 necessary to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any complications are fixed as quickly and safely as possible.
