I think old people who smoke who didn't know the dangers when they started, should be allowed to sue. But younger smokers who knew the risks shouldn't. Sure tobacco companies make it even more addictive by adding ammonia and other chemicals to cigarettes, but younger smokers knew the risks when they started. There's even a warning on the cigarette packet. But I've heard of people in America trying to sue tobacco companies when they get a smoking-related illness. Why? Is it because they want money, or because they can't take responsibility for their own choices?
