The governments new anti-smoking campaign focuses on lung cancer but doesn't mention COPD. Apparently COPD kills more people each year than lung cancer and breast cancer combined. Knowing abut smoking and lung cancer did not make me stop, Perhaps knowing about COPD as well may have made me think.Seeing people with oxygen cannula up their nose and them gasping for breath does make a point. It was a mild heart attack that made me stop. When I found out about it at the hospital I stopped there and then and haven't looked back.
