People who are physically reliant to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detox services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detoxification services, the person will have detox staff at their disposal around the clock to assure that any complications are handled as quickly and safely as possible.
