The studies selected by are all flawed in one way or another. Vaping has existed as a mainstream activity for over ten years. During this time there has not been a single illness or death due to vaping. Not one individual has presented at a hospital and been diagnosed. Not one.

Martin Dockrell wrote on behalf of Public Health England: “One of the most commonly held concerns is that e-cigarettes might cause ‘popcorn lung’. This came about because some flavourings used in e-liquids to provide a buttery flavour contain the chemical diacetyl, which at very high levels of exposure has been associated with the serious lung disease bronchiolitis obliterans.”

“The condition gained its popular name because it was initially observed among workers in a popcorn factory. However, diacetyl is banned as an ingredient from e-cigarettes and e-liquids in the UK. It had been detected in some e-liquid flavourings in the past, but at levels hundreds of times lower than in cigarette smoke. Even at these levels, smoking is not a major risk factor for this rare disease.”
