I remember my grandmother had one of those... (no offense to anyone here, I love you all) For all that don't know, it was basically an ashtray, with a fan attached to the bottom that sucked in the smoke, and just blew it out at a higher speed so one couldn't
see it. It was still obvious because of the smell though. Just reduced the haze a bit.
When I was able to vape in my old office, I was always paranoid about setting off the smoke alarms, so I used a
istick 50w with a
nautilus (full size) then just held in the vapor for twice as long as I normally did, and when I exhaled, there was no obvious vapor. Maybe a little wisp, but it worked for me
