STICK WITH IT, really, quit, don't smoke.

I wish some of my friends would quit, I've even brought it up to them in really secure manners, but I know they won't until it's too late.

I've seen people close to me go through lung cancer, it is NOT pretty. It's not worth it, you have an objective right now, so stick with it and just let it go. I'm serious on this shit, It's horrible to see someone try to quit, and not.... And it's even worse (it's horrible, and fucks with you emotional) to see someone go through lung cancer (not to mention die from it).

You can hang in there. It's not worth it to eventually put your close friends/family through that. STAY STRONG, don't smoke.
