Go ahead and look cool in front of all your friends, and when you start to get to the point where you want to smoke a bit more, don't worry.

Then once it gets to the point where you need to smoke, don't worry.

Then once you wake up ten years down the road with irreversable lung damage, a serious addiction to nicotiene, a raspy voice, and a chronic smokers cough, don't worry.

Because no matter what you will know that you consiously made the decision to do all of this to yourself, and you look cool while doing it.
