gee that sounds realistic
People have smoked for thousands of years and they are just figuring that out ?
Any scientist that would waste any research money testing MORE bad things that smoking might cause should be shot on site..
Lung cancer is a pretty good reason.. dont need to look much further than that.. I'm sure everyone knows someone who has lung problems from smoking, but do you know any blind people that didn't know what made them go blind , that just happened to smoke ? Infact how often do you see a blind man smoking .. hmmm that theiry needs some working on.
