What pisses me off about electronic cigarettes: people believing that they are perfectly ok to smoke around others and are healthy. Do they really think that because it's cleaner that the "water vapor" they breathe out doesn't still have nicotine in it? You're still getting your fix through it. Second hand smoke is still there, and when you're smoking in the middle of class or in a no smoking area, I'm going to get pissed at you.
