The problem with banning things is that it simply doesn't work. Moreover it simply ups the money in <whatever> for those that don't care.
If I were a really really cynical politician with an endless capacity for greed, then rather than do any useful work, I'd simply find a sympathetic cause in a sphere where the solution is seen to be a "ban" of some sort. Maybe disposable vapes.
Then, whilst the press do all my marketing for me, I'd make sure that all of my retail and commercial interests are aligned with the banned items. Testing kits, retail units, courses for enforcement officials etc etc.
Beware those that would ban - it's rarely for your sake.
