Men and women who are physically dependent to drugs or alcohol and want assistance will 1st 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 usually uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to make sure that any issues are resolved as rapidly and safely as possible.
