I don't even have an APV yet - still using a Halo Triton. But with its VV battery, 1.9Ω coil and good airflow, it does have the capability to make quite respectable vapor clouds. And occasionally I LOVE to blow big fat clouds of vapor. I can't explain why, but sometimes I just like it when it's so thick that I can't see anything through it for a few seconds.
BUT I ONLY DO IT WHEN I'M ALONE, at least when I'm the only one in the room, and only inside my own home. I don't do it to impress anyone. I have no idea why I like doing it. Probably because it's a novelty to me, still being new to vaping and all.
But sometimes when I'm by myself in my living room or in my home office, I like doing it. It (to my knowledge) doesn't hurt anyone or damage any property. The only negative effect of which I'm aware is that I go through more juice when I'm making
Cumulus Vaping Formations.
I personally have nothing against anyone else doing it, either - except that I'd rather they didn't do it in public, as it likely makes "anti-vapers" even more "anti-vaper", and we really DON'T need that.
If you like clouding, and you're keeping your clouds to yourself - or just between you and other clouders - then cloud it up as much as you like!
