Men and women who are physically reliant to drugs or alcohol and want assistance 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 usually uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox 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 generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering 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 variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can present detoxification services, the individual will have detoxification staff at their disposal around the clock to make sure that any difficulties are resolved as swiftly and safely as possible.
