People who are physically reliant to drugs or alcohol and want help will 1st go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detox services frequently 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 smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detoxification services, the person will have detox staff at their disposal around the clock to make sure that any complications are resolved as rapidly and safely as possible.
