No one does, Qazzz. They say to themselves, “God, this tastes like crap. There’s no way I could possibly need to do this everyday. I can smoke a few when I drink, but I don’t think I could possibly tolerate it more than that.”
That thought is reinforced even more the next morning, when you feel aweful, it tastes like someone crapped in your mouth, and you’re dehydrated. You think, “Man, this really is a terrible feeling. There’s no way I could get addicted to this. I don’t understand how someone could do this so much they get a nicotine addiction.”
You go out with your friends a few more times, smoke a few more each time, and love the enhancement it gives your buzz. You soon forget that you ever said something like:
Sure, alcohol is more fun and effective, but alcohol + nicotine is the best of both worlds (except for the need to do more laundry each week, and food doesn’t taste as good anymore).
Pretty soon, it’s not the enhancement of your beer buzz you’re after, it’s the fact that smoking a cigarette makes your brain stop nagging you for one. Once that nagging stops, you can get on with drinking beer and hanging out with your friends. Plus, if everyone else is lighting up, you might as well have a real cigarette instead of breathing in their secondhand smoke - that stuff just gives you a headache (a/k/a that nagging I mentioned earlier).
You soon find yourself smoking to ease the tension, and to relax, completely forgetting that you were plenty capable of relaxing all by yourself before you ever lit up. “But I get a little jittery if I don’t have that smoke after dinner. I enjoy my dinner experience more with a cigarette,” you say. Yeah, because you never enjoyed a meal in your life for 23 years before you discovered cigarettes, right?
Seriously, Qazzz. Don’t start. Don’t think to yourself that the negatives associated with smoking will help you stop at any time. Tell yourself that the negatives associated with smoking will help you NOT START.
