People who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is basically the process 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 provide appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can properly oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services frequently include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting 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 detox facility or drug treatment facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to ensure that any problems are fixed as swiftly and safely as possible.
