The flavour in your juice can definitely be smelt by those around you, it's not a myth or BS. We still have to be considerate to those around us and take care not to blow vapour clouds, much like we did with cigarette smoke. As I'm now using rebuildable atomisers I don't vape in restaurants like I used to with my small tanks and ego style batteries. The vapour is too much.
Finally someone sensible in this whole thing, not picking on everyone but self entitlement is going to lend itself to a lot of bad blood. I remember way back when I was smoking analog cigs there was the attitude of "I'll do what I want where I want" or " I can't smell it" if asked about the scent.
I'd thought that moving forward with E-cigs the idea was to educate and be better then the folks smoking analog cigs, but that can't just be in the ejuices and equipment that we have it also has to be in the attitude that we talk with people. I know someone who is hypersensitive to some smells and can actually pick them up on my clothes when I come by (not kidding) after vaping in the car as one of his favorite juices is one I enjoy as well. Again not picking on anyone imparticular but the better liaisons we are for ecigs the less that the FDA and the rest of the world has to fight with. If it were someone else s house or space if asked I'd step outside, if nothing else then I'd give the due respect of either finding a way to produce less vapor (high PG/VG ratio maybe) or just step outside right quick (or the towel method works as well). Either way to blow it off or such will just leave a bad taste for ECigs and Ecig users as people typically stereotype so one bad experience is damaging to everyone who vapes non directly.
As I went over this once with a local shop is that your taking a gamble in truth with flavored e-juices and peoples allergic reactions, I don't know everyone's allergies and I won't admit to doing such but it exists that I could without knowing harm someone else indirectly. I these days error on the side of caution anymore and just step outside, I've had a lot of positive comments doing this and on occasions made a friend or two along the way while outside in our smoking area ( 60% now vape because of it actually).
I'm just saying not to be self entitled and work out a logical compromise, if none can be found be the bigger person and step outside. You used to when you smoked Analog cigs so it shouldn't be that bad, worse case is you can also try unflavored e-liquid as I know that has almost (almost being very, very minimal) smell impact. Not trying to be the bad guy here but giving you'll a thought to ponder on, the real truth is someone will eventually come out the victor of the Cage match "FDA vs E-cigs" and anything we can do to throw the public opinion on our side is a winning combo.
