Health Canada is trying to ban almost all vaping liquid flavours. This is on top of measures to limit nicotine strengths and marketing. It is the nearest they can get to a prohibition without actually having to prohibit the most promising low-risk rival to cigarettes. The likely effects are obvious: more smoking. But in a bizarre twisting of reality and evidence, Health Canada finds that making vaping less attractive relative to smoking will… um … reduce smoking. And that’s how it justifies the measure. We respond with a counter-analysis.
