Immediate lung pulling isn't usually recommended for
vaping for two reasons - 1) the wick may not pick up juice fast enough and you can end up burning the wick which will ruin the taste experience for you (and the wick) 2) The nicotine via
vaping is generally absorbed in the mouth and through the nose. What I like to do is picture my grandpop sitting in his garden on a sunny Sunday afternoon puffing away at his pipe. Slow inhale roll it round the mouth, inhale if wished and then out through nose and mouth. But honestly, if the first two aren't a worry, then different strokes for different folks, and however you like to do it. Glad you're enjoying it!
