Men and women 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 simply the procedure 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 offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the person is as comfortable 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 smooth and safe as possible. The person in detox 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 rehab facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to ensure that any issues are handled as quickly and safely as possible.
