Just because your lungs are blackened doesn't mean you can't be green. San Diego-based company Greenbutts makes cigarette filters that not only biodegrade, but sprout when buried into what have to be the world's least healthy plants.

The filters are made out of organic cotton, hemp, and wheat flour, and the company says they "can be combined with a variety of seeds including grass, flower, fruit, herb, or even trees." Hey, if you make them sprout tobacco plants, you can have a fully self-sustaining terrible fucking habit!

Greenbutts is looking for investors and also selling panties and dog bandanas to finance its innovation. Man, what are you waiting for?
