Individuals who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eradicated 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. Detox services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification 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 receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth 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 detox facility or drug rehabilitation facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any difficulties are fixed as rapidly and safely as possible.
