Men and women who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing 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 individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detox services, the person will have detox staff at their disposal around the clock to make certain that any difficulties are resolved as quickly and safely as possible.
