A new study from Connecticut College shows that Oreos are as addictive as cocaine, at least for lab rats. According to the new study, eating the iconic black and white cookies activated more neurons in the rat brain’s “pleasure center” than drugs such as cocaine.

The research looked at the rats’ behaviors and the effects the cookies had on their brains. Rats were put into a maze and given the choice of hanging out near rice cakes or Oreos. The tasty sandwich cookies won that popularity contest handily.

Those results were compared to a different test, where rats were given the choice of loitering in an area of a maze where they were injected with saline or in another corner where they could get a shot of cocaine or morphine.

Much like humans, rats also prefer the delicious creamy center to the cookie. “They would break it open and eat the middle first,” said Jamie Honohun, one of the students who worked on the study
