People who are physically reliant to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is often uncomfortable and may carry 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 detoxification facility or a drug treatment facility which can adequately oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving 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 detox facility or drug rehab facility which can offer detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any issues are handled as quickly and safely as possible.
