Re: Hookah vs siggarets
There was some testing here in Germany.
A normal clay bowl, 10 grams of tobacco (probably Nakhla two apple) and one layer of pre-cut foil with pre-poked holes. They used self-lighting charcoals.
The result was: one hookah equals 1-2 ciggs. And the worst thing you're inhaling is CO, probably because of the charcoal. It would be interesting, how it'd be with natural charcoals.
But smoking is unhealthy anyways.
