watch the vid.
study going on regarding how different flavors cause different levels of harm.
tbh....i think we are all well aware that different flavor concentrates do different degrees of harm.
we all know menthol is gonna do more harm than lets say strawberry since we can feel the harshness with each lung hit. but its still pretty interesting to watch the experiment.
sadly i cant figure out the toxicologist's name to look up more info on the guy.
