As a smoker, you are constantly told about the millions of reasons why you need to quit smoking. I know that when I smoked, I was always being reminded that I was going to have a million strokes, high blood pressure, and all kinds of other bad things. Thinking back, it was really stupid of me not to listen to people, as these are the reasons why I don't smoke any more.

Blindness: Studies have shown that smokers are at a vastly increased risk for loss of eyesight. Turns out that smoking is around on par with moonshine for smart things to do for your vision.

Heartburn: I've seen research about this, but I didn't really need to, having experienced it myself. Before quitting, I smoked anywhere between one and three packs a day. I remember regularly waking up to severe heartburn.

Impotence: There are several studies out there showing a correlation between smoking and impotence. That should be enough to make you want to quit smoking right now if you're a guy.

Depression: Sure, depressed people are supposed to smoke. That's what you always see in the movies. It becomes self fulfilling, though, as being a smoker keeps you depressed and makes it even harder to enjoy life.

Of course, in addition to these three are the slew of well known health risks, ranging from emphysema to lung cancer. We all know how hard quitting smoking is supposed to be, but it's well worth it if you want to live a happy life.
