People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can appropriately oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can provide detoxification services, the individual will have detox staff at their disposal around the clock to ensure that any issues are handled as rapidly and safely as possible.
