Alex Carll was presenting his research about the impact of e-cigarette smoke on mouse hearts at an American Heart Association conference when a man from Juul Labs approached him and started asking questions. “He seemed genuinely concerned about the health implications of Juul,” said Dr. Carll, who recalled meeting the e-cigarette company’s medical liaison, Jeff Vaughan, in November as he stood by a poster of his research findings. “He said they were looking for people to collaborate with and that they could offer up to $200,000.” (Kaplan, 5/27)

A glimpse of student athletes in peak physical condition vaping just moments after competing in a football game led Stamford High School Principal Raymond Manka to reconsider his approach to the epidemic.
