People who are physically dependent to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and supply medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is getting proper rest, and supplying supplements and medicine as needed to make the detox process as easy and safe as possible. The individual in detoxification 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 present detoxification services, the client will have detox staff at their disposal around the clock to assure that any problems are handled as quickly and safely as possible.
