Individuals who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is often uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services typically 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 receiving proper rest, and providing supplements and medicine as necessary to make the detox process as easy 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 detox facility or drug rehabilitation facility which can offer detox services, the person will have detox staff at their disposal around the clock to assure that any problems are resolved as quickly and safely as possible.
