People who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is frequently uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and present medical supervision for people who are just coming off of drugs. Detox services often include insuring the individual 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 smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any problems are fixed as swiftly and safely as possible.
