I actually expanded upon my comment to cover that and it didn't post. Smoking it we can all agree isn't good for our lungs. However I wonder about the long term mental impact on regular users. The only ones I've known (and we're talking a couple of people so not a big sample) regularly lose focus and zone out when I talked to them (and they were sober).
