People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services often 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 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 type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to guarantee that any difficulties are handled as quickly and safely as possible.
