We've very likely reached the point where most people with either an adequate education or any exposure to media are aware of the dangers of cigarette smoking.
My eight year old can tell you about that you need the cilia within your lungs to be functioning well if you expect to hold your own at the gym, and that if you've been a smoker for any length of time, that probably ain't happening.
He could also tell you that more people die from smoke inhalation than burns in structure fires, but I'm straying from my intended topic again.
I found a current article in HealthNewsDigest listing five dangers smoking poses to skin health. If you love lists (doesn't everybody) or your skin, check it out.
