Instead of making the filter out of plain old cellulose, make it out of nitrocellulose--otherwise known as flash cotton. Put a firecracker fuse in the filter that extends a bit into the tobacco. Once you hear the fuse light and see the sparks, you've got about five seconds to toss the butt away before it bursts into a spectacular and extremely fast burning fireball.

Don't give them the 5 seconds, and I'll bun this. To much warning and it's more likely to end up in my face than theirs.

Mad Magazine did an article on this, back when it was good.

Yes! I would love this - weaponized butts! I'd go for quite highly nitrated cellulose - make it go with a bang, not just a flare. [+]

Don't worry about the powdered magnesium on the filter, it's just there to keep you from licking it. This message will self destruct.
