People who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and present medical supervision for persons 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, delivering proper nutrition and making certain the particular person is getting proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to make certain that any problems are handled as quickly and safely as possible.
