Fair point, but a teenager is less likely to get away with buying a vape from a supermarket.
The way I see it they're applying burn cream to a broken leg, I mean it's not going to do any harm and they are certainly going to act like they're single handedly saving the youths of the world from the dangers of giving up smoking.
but realistically all they will do is prevent the occasional adult smoker from being able to look at a disposable while they're waiting to pay for their shopping and think to themselves "hmm maybe blueberry blast will smell better on my breath than the arse end of an ashtray"
