Cigarettes.
I can go days without smoking but as soon as I do something where I'd normally have a cigarette after. I gotta have one.
If I'm at work I'm gonna smoke like half a pack cause I can, usually after throwing out recycling or heavy trash, drinking, if one of my boys pull up to chop it up we gonna smoke 4-5 cigarettesover an hour or 2, or if I'm waiting for a Lyft, uber or bus I have to have one.
If I'm just home doing fuck all I can go days without smoking if I'm not doing any of the above things. Dumb af.
