The term craving comes from Charles T. Tart's famous 1971 study, “On Being Stoned,” in which 150 marijuana users were observed and researchers looked at their cravings for sweets. In addition, these mice did not show an increase in appetite when they were administered the drug, demonstrating that the Munchies effect was also dependent on olfactory lobe activity. Another well-known cannabinoid, CBD, is gaining popularity because of its potential to relieve anxiety and chronic pain, but it can't trigger cravings like THC, Chen said.
Munchies is a brand of the line of snack mixes from the American company Frito-Lay and a line of biscuits with cheese. The chemicals in marijuana react with the brain to increase appetite, creating what is commonly known as a craving.
