Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and present medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the individual 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 detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to make sure that any problems are handled as swiftly and safely as possible.
