Cannabis causes worms to crave junk food, study shows.

Researchers at the University of Oregon have found that worms, like humans, become hungry and develop the munchies when exposed to cannabis. The study, published on 4/20, poured a cannabinoid called anandamide onto about 50 Caenorhabditis elegans worms and placed high- and low-calorie foods near them. The worms swarmed toward the high-calorie bacterial food. The researchers found that anandamide sparks neurons to become more sensitive to the odors of high-calorie foods. This is the first time that the munchies have been demonstrated in an invertebrate organism.
