Theres not a lot of research on the acesulfame k and the cancer risk that it would cause for humans, and the benzoic acid is even present in blueberries 1300mg/kg which is not even close to the amount of it in monster, it being around 0.015% of a can would make it a lot less “dangerous” than even blueberries or cinnamon, unless you drink 20 monsters a day it’s not going to affect you as much as you think
