Men and women who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for individuals 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, delivering proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detox services, the individual will have detoxification staff at their disposal around the clock to assure that any problems are fixed as quickly and safely as possible.
