Yes, smoking does
1. Harm your health
2. Affect the level of fitness you can achieve
3. Harm other people around you
4. Harm your unborn child
5. Make your breath, clothes, hair, house stink
6. Give you yellow teeth, wrinkles and generally dehydrated bad skin (it ages you -for all of those as vain as me)
7. Cost a fortune

As an ex-smoker I have to say I used to wake up every day feeling hideous with a blocked nose, phlegmy chest and raspy throat - it was vile!
