People who are physically dependent to drugs or alcohol and want help will first go through detox 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 executed in a setting which can supply appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual 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 rehabilitation facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to make certain that any complications are fixed as quickly and safely as possible.
