Good idea. I did. My lungs couldn't take smoke anymore. I've been strictly vaping for over 2 years and don't miss smoke even a little bit.

Why are so concerned about one person who doesn't vape much anymore? He obviously wasn't sufficiently motivated to switch. Quite a few people hear things like 'vapor gets you higher', 'vapor saves you herb'. Some people are just curious. Some find that they like the couch lock you get with smoke. If you gave up cigarettes for your health, think about the crap you don't get with vapor-carbon monoxide, benzene-both deadly in high doses and sleep inducing at the lower levels you get with smoke. Toluene is another- a solvent with intoxicating fumes (at low doses). The effect of these toxins are mostly what people miss with vapor. Vapor leaves you with more energy and even with a heavy dose late at night, you don't get any foggy feeling the next day.

If smoke doesn't bother you there's not as much incentive to go to the extra trouble and expense of vaporizing. But if you're looking for a healthier, stealthier high, with no harsh, nasty tasting (poisonous) smoke, you'll love vapor. You can tell I do.
