People who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and supply medical supervision for people 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 particular person is getting proper rest, and providing supplements and medicine as required to make the detox process as easy 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 supply detoxification services, the individual will have detox staff at their disposal around the clock to make certain that any issues are handled as swiftly and safely as possible.
