People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services frequently include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as wanted to make the detox process as smooth 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 detoxification facility or drug treatment facility which can offer detox services, the client will have detoxification staff at their disposal around the clock to guarantee that any difficulties are handled as swiftly and safely as possible.
