Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and provide medical supervision for individuals 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 making certain the individual is getting proper rest, and supplying supplements and medicine as wanted to make the detoxification process as easy and safe as possible. The individual 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 detox services, the person will have detoxification staff at their disposal around the clock to assure that any complications are resolved as swiftly and safely as possible.
