A student attending Florida International University in Miami, Florida, was complaining of chest pains. He said that pain he was feeling felt similar to a heart attack. He was extremely nervous so he went to the emergency room. When he got there, the doctors told him that his lung had collapsed and that he needed surgery immediately. They said that his lungs had block dots all over them due to something that he was inhaling. Chance, someone who had never smoked before, started juuling in 2016 and said that he would go through a pod within a few days. He and the doctors believe that juuling caused his lungs to collapse. https://nypost.com/2019/08/08/student-shares-shocking-images-of-collapsed-lungs-after-vaping-for-a-year/
