Men and women who are physically dependent to drugs or alcohol and want assistance will initially 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 carry risks if not performed in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services generally 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 particular person is getting proper rest, and providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The particular person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any difficulties are fixed as quickly and safely as possible.
