Well I hate to brake the news to you but you can die from cancer wether you smoke or not. It is one of the rights given to us and I for one respect that right for others to do so. I dont go around calling everyone who drinks (your liver can konk out), smoke, smokes pot, snorts coke, or what ever of the millions of other thinks that can make you die just as bad idiot. Both my parents died all 4 of my grandparents died of cancer and I smoke. Why ? Because when your time is up your time is up. If cancer doesnt get you something else will because it is your time to go.
My aunt on my fathers side did the absolute opposite then everyone else. She drinks (heavily I may add), smokes, smokes cigars, and pops pills and she has outlasted everyone in her family. And eveyone else took care of themselves didnt smoke (still got lung cancer). So yes I feel your pain I bought the people dying around me T-Shirt 7 times in less then 10 years but I dont hold them for what they have done. Life is short man and its better enjoy it and do the things you like to then to go fall in the tub or hit by a drunk driver or get sick from something else and enjoy life to its fullest then not to and you die anyway.
