>Why can't it be related to health? I don't think it's not related in some marginal way to health. I just doubt that it will have much impact on health given the terrible air pollution that people are already subjected to, regardless of whether they smoke. The stronger explanation is the political moral signaling. It would be a different thing if e-cigs were banned in a country that had very low air pollution and, say universal health care like Canada, because in that case the taxpayer is on the hook for paying for whatever the negative health effects of vaping are - and the connection between vaping and the condition would be much clearer.
