Individuals who are physically dependent to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and supply medical supervision for persons 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 making certain the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make sure that any difficulties are resolved as rapidly and safely as possible.
