I feel your pain Carl, lost my grandfather to cancer as well, from you guesses it, from smoking. It also nearly killed my mother when she got sick, and she was forced to quit or face certain death from blood clots. My father went cold turkey with her, and its been 2 years now. I fully respect peoples decision to smoke and do what ever they want, I just want them to realize that it can and will have consequences on day, and it may not be you who will be left to deal with it.
