People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The particular 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 rehabilitation facility which can provide detoxification services, the client will have detox staff at their disposal around the clock to ensure that any issues are resolved as rapidly and safely as possible.
