I've been smoking for about 12 years now. I enjoy it and the only reason I really think about quitting is the cost. I don't see where it's destroyed my taste buds. I season food to where it's good for me and everyone else has to add more salt, pepper, etc. to it. As for smell, if it's damaged that, then I have to say I'm glad. Otherwise, smelling perfumes, certain flowers, soaps, detergents, etc would probably kill me instead of just giving me a debilitating migraine.
I started smoking when I had bronchitis and a respiratory therapist gave me a menthol cigarette and told me to try it and see if I could breathe better. Contrary to popular belief, it did help. I'd always had problems breathing, especially when my allergies/sinuses acted up in different seasons. The menthol cigarettes do open me up more and allow me to breathe more easily. I actually have less problems now than I did before smoking. I went without cigs for a while and started having those breathing issues again so I ended up going back to smoking so I could enjoy life again. I've had inhalers, steroid inhalers, pills, etc. and none helped that much.
I don't blow smoke on people and don't want to be enclosed with cigarette smoke. While smoking my own cigarette doesn't cause me to have breathing problems, going into a bar or somewhere and inhaling a lot of smoke does. Perfumey odors do bother me a lot more than the smoke so going out in public is a risk I take. Like the lady a few weeks ago who had on so much perfume, I could smell it from two aisles away in the grocery store.
I've seen people die from lung cancer who never smoked a day in their lives. I truly believe that there are so many polllutants in our world that you can't blame just one. If you pay attention to the news reports, almost everything we eat, breathe, touch, etc. can cause cancer so it's no surprise that so many people die from some form each year. Seeing my father's battle with colon cancer for the past 6 years, I'd rather live life to the fullest and enjoy my time than do without everything that could possibly cause an early death. He feels the same way which is why he's opted out of chemo twice. He's testing cancer free once again after having a lobe in his lung removed last fall where the colon cancer had metastisized. He's been a smoker for most of his life but the doctors all say his lungs look great, except where the colon cancer spread to the one.
