The disposable black market & associated disproportionate rise in youth vaping in Australia results from the illegality of all vapes, not just disposables. It’s hard to imagine it becoming a burgeoning black market predicated solely on that vapers find the highly available, better value, relatively environmentally friendly option untenable. Overall a sensible move I think coming from a pro-vape perspective
To address youth vaping. The outcome of that has been that youth vaping is significantly higher than in other OECD member countries, and kids are now getting them from the ‘vape dealer’ whom may have other illicit drugs available. Cigarettes aren’t banned, only made unaffordable via progressive excise tax. That’s had its own unintended consequences of launching a new market for “chop chop” i.e. illegally grown unprocessed tobacco, as well as black market imports that sidestep the plain packaging laws, and tobacco gang wars in Sydney and Melbourne.
