There's a company that desperately wants your used butts. Starting in July, TerraCycle will provide free UPS shipping labels (postage paid by a shadowy, unnamed U.S. tobacco company) so people can mail in their cigarette remnants for recycling. Why care about the butts? Like the rest of the cancer stick, the end is toxic, made with a plastic that emits dangerous chemicals into the environment, and it doesn't biodegrade. The discarded butts will be turned into plastic pallets for industrial use. Just make sure your ciggies are thoroughly snuffed before mailing. We don't want the already-struggling Postal Service to go up in smoke.
