Your only hope is mooching from other people, but I suspect you've done plenty of that, and now nobody will give you more cigarettes. Suck it up and quit, since you obviously can't afford to keep smoking.

Out of the trash cans, plenty of butts there
Stop smoking or start bumming.
Stealing them is the only way.
sorry they don't' exist
