Dr. Farsalinos repeatedly mentioned during the interview that "vaping is still considerably better than smoking". That being said, their are risks involved and one of those said risks is diacetyl/acetyl. The diacetyl and acetyl problem however can be remedied if the flavoring companies and juice vendors exercise more caution before selling their products. I posted the link not to fear monger but rather, to face certain weaknesses and problems in an industry that is still at it's infancy and trying to find it's proper place and footing. I am really hopping that juice testing becomes mandatory. I for one do not want to prove those ....ers in the FDA right! I believe that their is still a lot of room for improvement in our somewhat ostracized hobby. I wanna "dance" for a long long time: I'm sure most of us do, no?
