This is the issue. Vaping is great for ex smokers, but it should absolutely not be taken up for its own sake. Twenty years or so ago, we made a lot of progress, smoking looked like it was going to be phased out in mist countries. Now vaping itself is becoming an issue, hooking kids for life on nicotine.
Along with disposable vapes, marketing and selling to kids should be banned and strictly enforced.
But removing the lifeline from ex smokers will just push them back towards tobacco, because nicotine dependency is real.
