Interesting article with an MU twist. I am neither a smoker nor a vaper, but this is quite disconcerting for people who are using the method to escape the dangers and addiction of cigarettes. Anyone paying attention around here knows how bad diacetyl is... to think that some vapers are inhaling 3-4x NIOSH's exposure limit is scary. At least with lung cancer, there's a chance you could survive... with diacetyl, there's no reversing the damage.
MU Chemistry may have just landed itself a supporting role in a Pulitzer Prize.
