Cellulose acetate aka cigarette butts, turns into dirt 4 months in the soil or a few years out in the open sunlight[1]. It's vastly more biodegradable than your hoodie, your socks, your Starbucks cup or even something like dried up egg yolk. I don't think people should throw it on the ground, because trash barrels and ash trays are there for a reason, but it's basically not an environmental problem at all. It's just unsightly litter.

If you actually want to solve environmental problems, how about solving actual problems instead of picking on lower class cigarette smokers who aren't causing any issues? It sure seems like an awful lot of "environmentalism" is nothing more than a disgusting social class pose.
