Individuals who are physically reliant to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as required. 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 persons who are just coming off of drugs. Detox services frequently include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detox services, the individual will have detox staff at their disposal around the clock to make sure that any complications are fixed as quickly and safely as possible.
