Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make certain that any difficulties are fixed as quickly and safely as possible.
