People who are physically dependent to drugs or alcohol and want help will 1st go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is often uncomfortable and may hold risks if not carried out in a setting which can provide 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 adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services usually include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is getting proper rest, and providing 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 form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to ensure that any complications are fixed as rapidly and safely as possible.
