Scientists are still trying to determine exactly why marijuana gives users the munchies. A 2015 Yale study suggested that marijuana tricks the neurological mechanism that, under normal circumstances, tells the body when to feel full.
"It's like pressing a car's brakes and accelerating instead," Tamas Horvath, the study lead author, said in a news release. "We were surprised to find that the neurons we thought were responsible for shutting down eating, were suddenly being activated and promoting hunger, even when you are full. It fools the brain's central feeding system."
Other research has suggested that marijuana heightens the user's sense of smell, therefore making users feel hungry regardless of how full they actually are.
