People who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox 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. Detoxification services typically 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 getting proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make certain that any complications are resolved as rapidly and safely as possible.
