I saw a guy get his taken away in front of me two weeks ago at the PP airport. It wasn't the little e-cig, it was the bigger vape pipe style. Man was that guy ****ed. All depends what agent you get, one agent let my light go through the time before and on that day they took my lighter away. I went down to the smoking lounge and there were 4 other smokers there that didn't get their lighters taken along with 3 that had and there was one guy with an e-cig that made it through.
Luck of the draw, pack it if ya don't want to lose it....
