People who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services frequently include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as needed to make the detox process as easy and safe as possible. The individual in detox 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 present detox services, the person will have detox staff at their disposal around the clock to make sure that any problems are handled as quickly and safely as possible.
