                                According to research, the active ingredient in cannabis, THC, stimulates appetite by interacting with the body's endocannabinoid system and increasing levels of the hunger hormone ghrelin. This effect, colloquially known as 'the munchies,' can vary significantly in duration depending on several key factors.
