I'll never be in favour of bigot prohibitionism of which this is a direct foreseable side effect, the onusian FCTC/COP6 event turning 10 years this month, e.g. a full decade while politicians have been continuously deceiving (after it was sabotaged by Russia...), satisfied to pretend they were protecting Public Health with the ban of flavours when it was only about their own political survival. Unfortunately the real issue was elsewhere, as you now proven to yourself. Yet YMMV!
What was there to expect from monster clouds fueled from e-Liquids invented in Asia? It's essentially mechanical and THC wasn't such a threat before, though already vilified by the secondary/tertiary by-products of tobacco combustion combined to real co-morbidy addiction from nicotine... But we discovered VAPORISM as a health-wise alternative, which itself sub-divides into consumption methods still not necessarily featured with safer use profiles, like more rational dosing and/or a transition to aroma/taste appreciation instead, etc.
In any case try not perpetuate the confusion between vapes vs THC. You can quit it all and save money, or learn to be more clever about it and finally counter-react to an attack conceived in Moscow, more exactly via sections 4.4.1, 4.4.2 and 4.4.3 of the report which helped politicians to deny all possibility of improvement without nuance via refusal to properly develop/regulate e-cigs, vaporizers and water pipes ever since. In other words the flavour ban saved their image and that's all about it, people who worked on microscopic droplet size as Enrico Bouchard in my canuck province were arrested and sent to prison so to deter their efforts, which actually worked as planned (for a while). But other manufacturers resumed course in this direction and now the idea resurfaces again, through at expensive cost. Too bad generations as ours had to get their time stolen!
The good news is, you've been given a salutory warning. No, it's not necessarily safe just because we see it sold everywhere, no it's not necessarily evil just because politicians want us to think so...
What we do know is that there's cheating everwhere and one hint of that is when talking in absolutes: seek the nuances, stay away from hype and other mediatic tricks like propagandist juxtapositions!
