Last I read, the hookah/water pipe/bong suprising was found not to be nearly as good as once thought.

I don't know about the site, but, yes, I suspect that is more like it.

Again, I refer all to druglibrary for information on this and just about anything else you can imagine.
http://www.druglibrary.net/schaffer/Library/mjfaq1.htm for FAQ, in cluding mention of the vaporizer.
