As well as making your clothes and hair smell of smoke, smoking can change the way you look and speed up the ageing process.
Smoking can stain your teeth yellow and can cause bad breath and gum disease which can even lead to your teeth falling out!
When you smoke cigarettes, fine lines develop around your mouth which makes your mouth look like a cats bum and can make you look older.
Through time, the skin of someone who smokes will age faster than that of someone who doesn’t smoke. That means smokers are more likely to have wrinkles and unhealthy looking skin.
