I've seen many people asking about vaping on a plane, and while it is courteous to ask the flight attendant, you will likely be rejected if you ask permission. It looks like smoke, and I firmly believe the air marshal sitting a few rows back will shoot you in the face when he sees what looks like a plume of smoke rising from a passenger.
So, I made a quick clip demonstrating how to avoid this plume. Simple and straight forward.
You pull the vapor into your mouth, take a deep breath, and hold it briefly, releasing the button before you stop inhaling. It all (or most of it) sticks to your lungs, resulting in little to no exhale cloud. I demonstrate this twice with a long drag (the only vapor you see is me showing that I actually did activate it), then the third is a brief puff to show how much vapor was being produced with no inhale.
