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 removed from one's system, which is frequently uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services often include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as wanted to make the detoxification process as easy and safe as possible. The person in detoxification 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 treatment facility which can supply detox services, the client will have detox staff at their disposal around the clock to ensure that any issues are handled as swiftly and safely as possible.
