I would imagine that any food you ate before/during smoking wouldn't matter. When you smoke the thc gets into your bloodstream pretty quickly. The food you ate would have no bearing on your high...because I'd assume your body has to absorb/digest that fat before the thc can bind to it? Correct me if i'm wrong
it would be a very very mild high because there wouldnt be that much thc stuck to the fat in the food.
