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 process of the drug being eliminated from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detox 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 usually 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 getting proper rest, and supplying supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The particular 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 treatment facility which can provide detox services, the individual will have detoxification staff at their disposal around the clock to make certain that any difficulties are fixed as quickly and safely as possible.
