You might not die but you might have a hell of a hard time believing that you're not gonna die once you go through the feelings you have once you've underestimated THC lol. But I think the toxic level of THC is too high to possibly reach to where death would happen. I really believe this because everyone has their uncomfort zone and eventually you'll reach it and not wanna ever touch weed again, but that feeling usually goes away when you come down lol.
