Had my first Marlboro red when I was 17. From my late teens to early 20s, it was a combination of Marlboro lights, Camel Turkish Royals, and sometimes Camel Blues.
I never smoked at home. Only at friends houses, hang out spots and restaurants when you could still do that. This was in the early 2000s. It was always a way for me to mellow out or have 'something to do.'
Switched to American Spirits in my late 20s. Early 30s, I rarely smoked. I'm now 35 and maybe had 2 cigarettes in nearly a year. I find alternatives. I still enjoy being around it, however.
