People who are physically reliant to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is often uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and present medical supervision for people who are just coming off of drugs. Detoxification services usually include insuring the individual 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 necessary 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 detox facility or drug rehab facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any difficulties are fixed as quickly and safely as possible.
