Rats also experience increased appetite when exposed to cannabis, according to recent findings from the University of Calgary. Dr. Matthew Hill, a neuroscientist at the university, noted that rats exhibited a significant increase in eating behavior after inhaling cannabis vapor, commonly known as experiencing “the munchies.” The study aimed to explore the effects of cannabis on rats’ appetite, observing a notable surge in food consumption among rats within the first hour of being intoxicated with cannabis vapor.
Cannabis activates the brain circuits that are involved in hunger and eating, tricking the brain to want fatty, sugary food.
While the concept of the munchies is widely recognized among cannabis users, there was skepticism regarding whether it was a real physiological response or merely a placebo effect. Dr. Hill emphasized the importance of studying the effects of cannabis inhalation on rats, as previous animal studies predominantly utilized injectable forms of cannabinoids, which differ in their behavioral impact compared to inhalation, the primary mode of cannabis consumption in humans.

The joint study conducted by the University of Calgary and Washington State University unveiled intriguing insights into the voracious eating behavior of rats under the influence of cannabis, even when they were not initially hungry. Dr. Hill observed that rats exposed to cannabis showed renewed interest in food consumption, contrasting with the indifferent attitude of rats that received a placebo instead of cannabis.
Surprisingly, the rats displayed no preference for specific types of food, as they equally enjoyed high-fat and high-carb options. Dr. Hill highlighted that rats seemed to have an enhanced appetite for all types of food, regardless of composition.

Furthermore, a parallel study by Washington State University involving human subjects found a notable preference for beef jerky among individuals under the influence of cannabis, indicating a specific food preference during heightened appetite.
Implications for Human Health
Besides confirming the reality of the munchies phenomenon, the study carries significant implications for individuals dealing with certain health conditions, according to Dr. Hill. Notably, cannabis has been recognized for its potential in alleviating chemotherapy-induced nausea, a condition that often leads to aversion to food consumed during periods of nausea.
Dr. Hill suggested that cannabinoids in cannabis could aid in reducing nausea and stimulating appetite post-chemotherapy. Additionally, there is potential for exploring the use of cannabinoids in managing eating disorders like anorexia, although this application remains
