This is why smoking pot triggers cravings

The THC in cannabis affects the very brain cells that are normally supposed to curb appetite. The active ingredient in cannabis ensures that the nerve cells that are supposed to stop hunger suddenly produce the wrong messenger substances for it. In the process, they produce a hormone that particularly stimulates the appetite. As a result, you feel hungry even though you are actually full. In addition, the food tastes even better because the THC stimulates the brain's reward system.
