People who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The 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 rehab facility which can supply detox services, the individual will have detox staff at their disposal around the clock to assure that any problems are fixed as rapidly and safely as possible.
