Truth is, whatever their environmental impact, banning disposable vapes would be a massive backward step for a government that has put its faith in e-cigarettes as a safer alternative to smoking.
It would also deny consumers choice although the unregulated black market would quickly meet demand because there is one very simple reason why single use vapes are popular with consumers - convenience.
As I wrote here seven years ago:
My gut feeling – based on no research whatsoever – is that if hundreds of millions of smokers worldwide are to switch to vaping (e-cigarettes or heat not burn products) the device has to be as simple to use as a combustible cigarette.
I based my argument on the fact that in the 20th century the convenience of the mass manufactured cigarette effectively made the pipe obsolete, and the only way for the cigarette to be consigned to history in the 21st century is for consumers to be offered something that is just as easy (and pleasurable) to use as the combustible cigarette, and many e-cigarettes aren't.
