People who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detoxification 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 men and women who are just coming off of drugs. Detoxification services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as wanted to make the detoxification process as easy and safe as possible. The individual 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 treatment facility which can supply detox services, the person will have detoxification staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
