Men and women who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any complications are resolved as swiftly and safely as possible.
