Researchers at Connecticut College say the cookies can be just as addictive as cocaine.
The study found that rats eating the popular snack actviated more neurons in the brain's pleasure center than exposure to drugs. Scientists say the rats formed an equal dependency on Oreos as they did when they were injected with cocaine.
They also say just like many humans, the rats tend to eat that creamy filling first.
The study claims that high-fat foods loaded with sugar stimulate the brain in the same way that drugs do.
