Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to guarantee that any difficulties are handled as swiftly and safely as possible.
