All good points and well made. When I switch to MYO, I will have to fight the temptation to make comparisons to the Marlboro of old, much like someone switching to a vegetarian diet resists the urge to compare vegi burgers to beef burgers. I will have to take them on their own merits and find what works for me. One thing that occurs to me is that it will be a new chapter in the smoking aspect of Marcus' and my relationship as we explore and find what works for us.
I believe you are correct that FSC's will kill more smokers at a much faster rate than regular cigarettes. In my profession I see the effects of breathing toxic chemical fumes on a regular basis. the cancers caused are different and often more aggressive than lung cancer attributed to smoking. They destroy our lungs in a different manner. Look at the x-ray of someone who has spent 50 years breathing hazardous industrial gasses and someone the same age who has spent the same time smoking every day and you will see that they are very different. In the smoker's x-ray you will see that the lung tissue is quite literally destroyed. It is no longer there to absorb oxygen. In the other person's x-ray you will see that the tissue remains, frequently in what appears to be good condition. The lungs just don't work anymore. I tried to explain to a colleague recently why the higher toxicity of FSC's bothers me. She couldn't understand why someone "Who has so little respects for her lungs would even care." I'm afraid I didn't get very far. Of course, she is the same colleague who, several years ago, when she saw I was sanding dried sheetrock seams to prepare them for painting without wearing a dust mask, didn't think it was humorous when I told her my lungs have a protective layer of tar and mucus.
