Individuals who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not executed 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 treatment facility which can effectively oversee and present medical supervision for people who are just coming off of drugs. Detoxification services frequently include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detoxification services, the person will have detox staff at their disposal around the clock to ensure that any difficulties are resolved as rapidly and safely as possible.
