Men and women who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services frequently include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detoxification services, the client will have detoxification staff at their disposal around the clock to make sure that any difficulties are fixed as rapidly and safely as possible.
