Individuals 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 simply the process of the drug being eradicated 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 needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as required 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 supply detoxification services, the individual will have detox staff at their disposal around the clock to guarantee that any complications are handled as rapidly and safely as possible.
