if you have a full stomach before eating it will take the stomach longer to break down the food and thc all at one time, it will take longer to feel it and the high will be less in my experience. the best time i eat edibles is right when i wake up and before i eat anything because edibles last longer and i want to get the most out of them. but latest i eat them early afternoon and skip lunch till i feel the full effects. munchies are always best for last.
