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 removed from one's system, which is typically uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and provide 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, supplying proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can provide detox services, the individual will have detox staff at their disposal around the clock to assure that any difficulties are handled as swiftly and safely as possible.
