Men and women who are physically reliant to drugs or alcohol and want help 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 generally uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and provide medical supervision for individuals 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, supplying 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 variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to assure that any complications are handled as rapidly and safely as possible.
