Men and women who are physically dependent to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services generally include insuring the person 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 providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to guarantee that any issues are handled as rapidly and safely as possible.
