And one more thing, I'm not sure if you know this, but most shihsa brands out there have 0%tar and 0.5% nicotene (out of a 250g jar). That's barely anything at all, and I've always been the type to think that hookah smoke is cleaner and healthier than cigarette smoke. I've drawn my conclusions from basic common sense as well as observations. Take a look at this intereting thread an old member of ours made here not too long ago. It clearly shows some of the benefits of smoking hookah vs. cigarettes.
