I have noticed myself "playing" (for a better lack of words) with my vapor. Ill get a big drag, let a little puff out before inhaling it all up, blow some out, stop mid stream blow a smoke ring or two, let some more out, suck it from my mouth up my nose before exhaling it all. Probably looks very silly to someone else watching, but its just fun/entertaining. I will say adding a small nose hit to the mix definitely brings all the flavors out more strongly.
