Smoking

At this point, everybody knows about the harms of smoking. Yes, it’s a choice, but that doesn’t mean it’s a good one. Because of the harm of second-hand smoke, most public spaces have gone smoke-free in recent years. The carcinogens found in cigarettes and cigars have been linked to a bevy of cancers, high blood pressure, heart and respiratory problems – basically it messes with all your vital organs. Okay, some people say they only smoke when they drink – but too much alcohol isn’t great either. Smoking drastically shortens your life, and reduces the quality of life at the same time. So this is a habit you really need to try kicking.
