I smoked because I looked like a fucking badass doing it!
Of course that's my own opinion, but I started smoking because I thought it looked cool and b/c I had time to kill.
But eventually (about 18 years), I got tired of my hands constantly smelling like smoke, my hair smelled of smoke, all my clothes smelled of smoke. My car reeked of it. Thankfully, I never smoked in the home, so I just smelled, but not the rest of my stuff.
When I quit smoking, I had to get rid of the car because every timed I turned on the AC, smoke came billowing out instead of cold air!
Even though I miss the ritual of smoking, I don't miss the stench. To this day, when I smell smoke and food, I get nauseous.
