People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving 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 carried out in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can appropriately oversee and provide medical supervision for men and women who are just coming off of drugs. Detox services generally 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 receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual in detox 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 detox services, the individual will have detoxification staff at their disposal around the clock to make certain that any complications are fixed as rapidly and safely as possible.
