Smoke anybody?

What makes smoking among teenage so cool? Well, i don't really know but what i know was that i once smoke and it's hard for me to stop. In fact its being over 7 months without smoking, and i now find it better then before. I'm not saying this because the world is against smoker, I'm saying this because i understand the change in. For an example, i once run 4.4km run(when i was smoking) and i when breathless, but after i stop smoking i did a run the same distance as the before(4.4km) but to my surprise i was doing extremely well. Not saying that smoking should be band but i think that they(the smoker) should think of what they really want in life. Anyway in my working place, there about 5 smoker. Can't really do much only advise could be given but i can't blame them, i mean all of them got their own problem. But in other words i once a smoker so i can't say much due to the reason that i understand what the go through.
