Smokers know smoking is bad. Smokers don't change doctors until they find one that tell them smoking is good for you. Smokers don't make their children smoke. Smokers are so much taxed that it covers for cancer traitment costs/insurance. There are tons of ads saying smoking's bad, even on cigarettes packages. Nobody ever told "stop smoke shaming me" unironically. Seeing a smoker doesn't make you want to gouge your eyes out. And I could continue all day...
