You’ve got a point, but if you’re REAL, you also know that a lot of people simply cannot quit and need a decent replacement to stay off tobacco. This is the main reason why now you see a lot more people switch to vaping and stick with it, thanks to the better equipment that gives people that throat hit, that flavor, that cloud production and nicotine delivery.
In my book, once you’re an addict, you’re an addict for life and there is plenty evidence to suggest this as well (whether you’re talking about alcoholics, smokers, drug users, etc). So it’s all going back to what gives you the best ratio of harm reduction to what keeps you off the most harmful tobacco.
Sure, there are satisfying MTL vapes and there are products in liquids that can be labelled as being “bad”, like diacetyl, formaldehydes etc. But you have to stay realistic and look at evidence what these “bad” products do. And sure, we still need more testing and more assurances, but at the moment, things aren’t looking so bad for the current vapers, especially in comparison with their previous habits and that is what it’s all about.
Dyes are a whole different story though. To me, they fall in the same category as the labeling that might attract attention from young children. It’s not done. Not to give your e-liquid a recognizable color and not to color the vapor either. This is even beyond the question of whether this is healthy or not. It is also for this reason that you’ll find countries that will ban any type of coloring and I’m in full support of it. Unlike the type of mods, attys or flavors for liquids, this coloring adds nothing that an ex-smoker would need to quit smoking. The only thing this will do is draw even more negative attention to vaping and it’s something we don’t need.
