I often wonder how much car pollution attributes to cancer... Sometimes I wonder if that is more problematic than cigars and cigarettes together. It seems to me that focusing on smoking may be an alternative to causing the auto industry and oil companies from getting hit with lawsuits. Everyone is effected by gas fumes and smog but now adays very limited groups are effected by cigar and cigarrette smoke. When or if they make smoking illegal where will they place the blame for lung cancer next? Just a strange thought
