People who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eliminated from one's system, which is often 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 treatment facility which can correctly oversee and provide medical supervision for persons who are just coming off of drugs. Detox services frequently include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as smooth 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 offer detoxification 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.
