I've done it. Don't worry about trying it, smoking is five times as intense of a high imo. When I smoke more than a few hits, I start to get blasted. If I smoked two blunts orthree joints or five bowls I'd be blazed as fuck. But I could vape all day and not feel very high at all. So I wouldn't worry about the health part, but as far as quality of high goes, I'd stick to smoking Its a sure thing.
Next time your high, check me out. I rap. http://soundcloud.com/laconicflow
