People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and supply 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 person is receiving proper rest, and supplying supplements and medicine as wanted to make the detox process as smooth 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 rehab facility which can provide detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any issues are resolved as rapidly and safely as possible.
