REALLY. Cigarettes are nothing but cancer sticks. Its your choice. SO go ahead and die young if you really are that insecure about yourself that you have to smoke to feel cool.
I'm sure you've heard all the nasty statistics. But just think how cool you really are to be strong and stand up to peer pressure. Thats the mature thing to do. Don't smoke.
And if you already do, crush the habit. It SUCKS.
