They are not bullshit at all. I use one, but not the ones on TV or at the gas station. I have an Ego battery and use MT3S for the "clearomizer" (the atomizer and tank), and vape a juice that's made right here in my hometown. It looks something similar to this, but this is just a pic I nabbed of the ecig subreddit, and my clearomizer (the part on top that burns and holds the jucie) is a little different. It's about the size of a cigar. http://imgur.com/8o5zkPu Humanodon pretty much said it all, and I agree with everything he said. I'd say they are definitely safer than cigarettes just based on the hundreds of fewer chemicals (most ecig juices only have like 3-5), but yeah inhaling anything can't be that great for you. Consider it harm reduction, yet you still get that similar feeling of smoking and you still get nicotine. Plus it tastes better, doesn't stink, you don't have a butt to throw away, doesn't cost as much, and you can do it in the bathroom stall at work while playing cell phone games.how bullshit are e-cigs? I was skeptical as soon as I saw the commercials hit TV.
