People who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately 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, offering proper nutrition and making certain the person is getting 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 variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as rapidly and safely as possible.
