People who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services frequently include insuring the client is as comfortable 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 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 offer detox services, the client will have detoxification staff at their disposal around the clock to make sure that any issues are resolved as rapidly and safely as possible.
