I read somewhere here on curezone that somebody (or some people) think that the non-additive hand-rolled cigarettes are not harmful to the body, it is only the additives in the tobacco and paper, not the tobacco and paper themselves.
I don't know if that is true (that is a pretty strong statement) but I'm sure it is MUCH better and switching as you have sounds like a smart idea on your part (and the person who suggested it).
