Individuals who are physically dependent to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services generally 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 providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detox 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 rehabilitation facility which can supply detox services, the client will have detox staff at their disposal around the clock to make sure that any problems are handled as quickly and safely as possible.
