It would also be rather obtuse for a conservative person who, presumably believes in consumer driven free market economics, to bemoan the loss of pubs due to a smoking ban. Smokers have represented a dwindling proportion of consumers for years (though we are now into diminishing returns when it comes to reducing smoking further). Pubs, like any offering, have to diversify or die.
The issue now with vaping is different and requires a different regulatory response. We do not yet have research evidence on long term effects, but there is evidence of the direct marketing appeal to the young, mirroring past cigarettes marketing.
