Ooh so is that why Boromir had to die first as a morally suspect non smoker?
I have finally got around to looking at the EE ROTK appendices and commentaries and Gandalf coughing on his pipe in Minas Tirith (unlikely given his reborn Maia constitution - but in the scale of things a minor "crime") was apparently to appease the rabid non-smoking lobby in the US.... which I find rather bizarre......
