I think what WILL cause the FDA to act is if enough of a stink is raised by the non-smoking community action groups... Right now, they've got the FDA and the feds/local governments on their side - smoking is evil, smoking is bad, you smokers either have to quit or pay huge sin taxes.... don't pollute my air.... etc....
So we've cleverly come across a way to circumnavigate the smoking bans. We've found a way to avoid the huge sin taxes and it doesn't involve sacrifice on our part. We still get to "smoke." It's a classic example of "I get to have my cake and eat it, too!"
Technically, these devices found a loophole in the laws....no burning tobacco = no smoke, therefore, I can "smoke anywhere." But, the anti-smokers aren't going to like this, it's going to stick in their craw that we've found a way to be happy, and they've got the ears of the politicos who make the laws. Short and sweet, people, if we FLAUNT the loophole, it will be CLOSED.
I abide by all the non-smoking regulations currently in effect in my state. I smoke only where I'm allowed to smoke analogs. Some may think this is pacifistic thinking, but I'm in for keeping my head down, so long as I can keep my vape.
