Men and women who are physically dependent to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not executed 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 effectively oversee and present medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification 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 detox facility or drug treatment facility which can provide detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any issues are resolved as rapidly and safely as possible.
