People who are physically reliant to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is frequently uncomfortable and may hold risks if not performed in a setting which can supply 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 provide medical supervision for individuals who are just coming off of drugs. Detox services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can offer detoxification services, the individual will have detoxification staff at their disposal around the clock to make certain that any issues are fixed as rapidly and safely as possible.
