Individuals who are physically dependent 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 removed from one's system, which is typically uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as needed. Detox services are offered 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. Detox services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detox services, the client will have detoxification staff at their disposal around the clock to guarantee that any difficulties are resolved as rapidly and safely as possible.
