People who are physically reliant to drugs or alcohol and want assistance will initially 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 frequently uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detoxification services, the client will have detox staff at their disposal around the clock to assure that any issues are resolved as quickly and safely as possible.
