Does smoking cigarettes make you irritable?

Well, I am not a smoker..but..I bought an e-cig today to try it today. 'cause you know, why not, theres never been a healthier way to smoke ^^...anyway a couple hours after I smoked it I got so irritated after losing a game of league of legends..more than ever before.. I felt like punching a hole through my computer monitor. I then remembered about the e-cig and it all made sense. I then took four big drags of the e-cig and calmed myself down. Think im gonna throw this thing out before i get addicted haha. Anyway, hope that helps.
