Discarded cigarette butts contain cellulose acetate that lasts for years, long after the paper covering is gone. If you want to put them to good use (but not as Teddy Bear stuffing, for example), they might be good for fly fishing.

Tie the fluffy fibers to a hook, as wings and legs of local insects that fish love. You get inexpensive trout flies, and cleaner streets.

Don't just put a plain old cigarette butt on a hook. I'm not dissin' Berkeley, just saying you won't catch fish that way. [Amos Kito, Oct 05 2004, last modified Oct 21 2004]
