One man's banned endrunkener is another man's legal auto fuel. From the AP:

Truckloads of Four Loko and other alcohol-laced energy drinks are being recycled into ethanol and other products after federal authorities told manufacturers the beverages were dangerous and caused users to become "wide-awake drunk."

Thank you, Slog tipper Rob. Also, I predict fumes from Four Loko-derived fuel will soon be identified as the new cause of autism.
