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