If you have ever heard someone joke about eating up everything after using cannabis, you might be surprised about how much real science is behind it. Scientists have officially confirmed that the “munchies” are not just in your head. They are a real biological reaction that happens in your brain. And the latest research might change the way we think about cannabis and food forever.
What Scientists Discovered
A brand new study from researchers at Washington State University and the University of Calgary looked closely at how cannabis affects hunger. The study was published in the respected science journal Proceedings of the National Academy of Sciences. and centered around cannabis and a diverse set of volunteers. The researchers had 82 volunteers between the ages of 21 and 62 vape either a low or high dose of cannabis, while another group received a placebo (meaning they got nothing real). Afterward, everyone was observed to see how much they ate and what foods they chose.
The results were clear. People who used cannabis ate a lot more food than those who did not. It did not matter how recently someone had eaten, what their body size was or whether they were male or female. Cannabis made people hungry across the board. What made things interesting was the types of foods that folks were craving. Most people assume the munchies lead straight to chips, candy and junk food. The results from the study showed something that was very unexpected. People reached for all kinds of food, not just sweets or fatty snacks.
One of the biggest surprises that turned out to be one of the most popular choices was Beef jerky. Even the lead researcher, WSU psychology professor Carrie Cuttler, admitted she did not see that coming. Water was also a top craving, which makes a lot of sense when you think about how dry the mouth can be after consumption. Some people craved carbs while others wanted a high amount of protein. A few folks in the study did go for fatty snacks but there was no indicator of a single “munchie food” that everyone chose. It seems like cannabis just makes your brain want food in general, regardless of the type.
Whats Happening In Your Brain
The answer comes down to a part of your brain called the hypothalamus. This small region helps control hunger and many other body functions that we go through without notice, on a daily basis. When you use cannabis, THC (the main active ingredient) enters your bloodstream and travels to your brain. It then “hijacks” your body’s natural hunger signaling system, called the endocannabinoid system. In doing so, no matter if your stomach is already full, your brain gets a signal that directs you to “eat more.”
Researchers also tested this effect on rats and found the same thing. The rodents that were full and had no interest in food suddenly started working hard to get more food after receiving cannabis. Once the cannabis wore off, they simply stopped.
Why Does This Actually Matter
This is not just a funny science experiment to try after a visit to your local dispensary. The findings from these types of studies have authentic and warranted uses. Many people with conditions like HIV, AIDS or cancer struggle to eat enough food because their illness or treatment kills their appetite. Chemotherapy, for example, often causes severe nausea and loss of hunger in cancer patients. According to the researchers, cannabis could be a helpful medical tool for these patients and others who may suffer from eating disorders as well. By understanding exactly how and why the munchies happen, doctors may one day be able to help patients with appetite loss eat enough to stay strong during treatment.

Other Cool Things Science Has Found
This is not the only study to look at cannabis and food cravings. Here are a few other results from research studies that have discovered some pretty interesting findings:
A 2024 study from WSU found the exact group of brain cells that turn on when cannabis is used and trigger hunger. Think of them like a switch that has the ability to get flipped on or off and it signifies your appetite.
Examining the effects of cannabis and glucose regulation, a 2024 meta-analysis found that people who use cannabis are about half as likely to develop type 2 diabetes compared to non-users.
Despite the munchies, a 2022 study found that states with legal cannabis actually have lower rates of obesity. This is even more surprising but true.
A 2019 study showed that ice cream, cookies and chip sales actually increased in various states after they allowed recreational cannabis. A true indicator that cannabis and food can have a close relationship.
The Bottom Line
The munchies are a real thing beyond what you’ve seen and heard from people who partake. Those cravings are brain-powered and they do not care what kind of food is used for satisfaction. Scientists are just beginning to understand how this all works due to recent studies and the potential medical benefits are exciting. Whether you are curious about the science or just wondering why you reached for beef jerky at midnight, now you have your answer.
