Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is often uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring 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 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 supply detoxification services, the client will have detox staff at their disposal around the clock to guarantee that any problems are resolved as rapidly and safely as possible.
