Disposable/single use vapes have been illegal to sell in the UK since the first of June this year. This is the kind that the article is talking about litter everywhere as people just throw them away when done rather then refilling them. Vapes themselves are still legal to sell. It has only been a couple of months though so likely will still see people using them for a bit but I would hope to see their use start to tail off quite quickly now as you should no longer be able to buy them.
