A new study published in the Environmental Health Perspectives has found that 75% of flavored electronic cigarette liquids contain Diacetyl. Diacetyl, in case you didn’t know, has been linked to severe cases of respiratory disease and can lead to what is known as “Popcorn Lung”. “Popcorn Lung” got it’s name because it first appeared in factories that produced microwave popcorn. Diacetyl was used to reproduce the butter flavor. It is slowly being removed from most microwave popcorn. It apparently migrated to e-cig juice.

Two other chemicals, acetoin and 2,3-pentanedione both of which have been identified as “High Priority” because of their link to respiratory hazards were also found in several e-cig juices.
