smoke

Normally, you don't notice your own scent, but right now I can smell myself. I smell like cigarette smoke. Smoking is offensive to all five senses and harmful to your health. And yet I continue to smoke.
I've "tried" to quit, but never really tried. I mean, I know I'm polluting my body with harmful chemicals, and I've known someone that died of lung cancer.

I'm about to go out for another.
