I know a lot of people who view smoking as a gross and terrible habit.
I, for one, deny that claim completely. I love the smell of smoke, it's relaxing, and it is a way to socialize. Specifically for me, i have chronic headaches, normally get one a day, 3-4 of those per week are migraines. I've tried many different painkillers and the only thing that lessens the pain of a headache of mine is a good cigarette or 2. Then someone comes along and starts screaming at me about my habit that kills people every year, and the headache comes back. I hate crazy people who think that smoking a 3-4 cigarettes a day is worse than binge drinking every damn night. I'll kill my lungs this way slower than they kill their liver, and i can live with that.
