Individuals who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can appropriately oversee and supply medical supervision for people 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, delivering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth 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 detoxification facility or drug rehab facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to assure that any problems are resolved as swiftly and safely as possible.
