People who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and present medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as required to make the detox process as easy 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 treatment facility which can offer detoxification services, the individual will have detox staff at their disposal around the clock to make certain that any difficulties are resolved as rapidly and safely as possible.
