Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and supply medical supervision for people who are just coming off of drugs. Detox services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is getting proper rest, and supplying supplements and medicine as needed 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 detoxification facility or drug rehab facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to make sure that any complications are resolved as swiftly and safely as possible.
