People who are physically dependent to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The particular person in detox 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 offer detox services, the person will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as quickly and safely as possible.
