Cigar butts should be to a point, but, cigarette filters aren't considered biodegradable however. It takes a real long time for them to decompose and they have hazardous chemicals in them.

Yeah and some people say styrofoam cups and plascit are not biodegradeable. Those people have never run out of gas on the side of the road and had to walk somewhere. You can find styrofoam cups and all types of plastics on the shoulder that are rotten and THIN.
