Government Intervention - Australia Bans Imported Disposable Vapes

Australia is banning the import of disposable vapes among a range of measures to tackle a perceived rise in vaping among young people. The other measures include stopping single-use vapes from being made, advertised, and supplied in the country. This is despite the fact that you already need a doctor's prescription to buy vapes in Australia.

Is this good economics though? There seem to a be a lot of costs associated with all of these moves, and what's the evidence on whether or not vaping is better than smoking? And given the preponderance of vaping, won't a shadow market for vapes simply emerge?
