People who are physically reliant 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 eradicated from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as necessary to make the detoxification process as smooth 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 detox facility or drug rehabilitation facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to guarantee that any complications are handled as quickly and safely as possible.
