Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the particular person is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to assure that any complications are resolved as rapidly and safely as possible.
