The ban is on cigs not really vapes it seems (apart from the flavored ones that attract kids). In which case people are being steered toward vaping, which will likely do well in competing against black market cigs. If the goal is to keep kids off the worst of the worst, focusing on cig bans while keeping unflavored vapes on the table would seem to be the most effective compromise.

I’m not endorsing it.. but just in terms of the gov achieving its goals (one of which is cancer reduction) it seems they will succeed to the extent possible with this approach.
