I had a guy alert me that this thread has taken a strange turn and after browsing though the latest comments he sure is right. I'll respond to some of the comments, I may have forgotten some of the issues and some of the material was deleted but I'll do my best here to remember
Did someone really suggest that WTA be subject to human trials before being allowed to be sold? I'm pretty sure that tobacco has a pretty long history of human trials already. That's one of the funniest things I've heard on here in a while.
As vapers, we are consuming tobacco in an unburned form, and therefore are looking to enjoy certain constituents of the product without having to breathe in smoke. It's fairly well accepted that by not burning it, we are enjoying several benefits here. Some of these benefits may be seen as harm reduction, although that's not even a term I would use.
I think a better way of looking at this is in terms of the relationship between costs and benefits, and with the costs I'm speaking both of monetary and health costs. If it were the case, for instance, that smoking makes us feel so much better than vaping, then it could be perfectly rational to want to continue smoking, if you look at overall utility, which we need to. So in other words, having a shorter but significantly more enjoyable lifespan could hold more enjoyment overall and therefore be the better choice.
This was just the subject that I was debating before I tried WTA. I felt better smoking than vaping regular juice, and a lot of people do, which is why so many go back to smoking. Some feel fine just vaping, and some perhaps feel better. So this is pretty individualized.
So one of the reasons why I bring this up is that we can't just look at WTA and non-WTA vaping as identical goods, then make guesses as to their relative safety and decide which we should prefer based upon just that. This in fact would be outright stupidity.
As for the safety, while it may be the case that WTA is less "safe" than non WTA, we can say with absolute certainty that it is safer than inhaling burning tobacco fumes, quite a bit safer in fact.
So for those who use WTA or are looking to try it, this is the only issue here. We enjoy using tobacco of some form or other, and if this is the form we most enjoy, and in particular, enjoy it significantly more than non WTA, there is no need to think on the matter any more.
As it turns out though, there are people who enjoy meddling in topics where they obviously have little grasp of the real issues here, and therefore choose to throw stones into a pond whose waters are already very clear and beautiful to behold. None of us who have the proper understanding of what's going on here are going to be fooled though.
