Indiana residents will be barred from purchasing, selling or using a powdered form of alcohol under a bill Gov. Mike Pence has signed into law. Pence signed legislation Wednesday that bans the substance. The bill also calls for further study of the issue this summer. A powdered form of alcohol called Palcohol received federal approval in March and can be mixed with any liquid to create an alcoholic drink. It comes in rum, vodka, cosmopolitan and margarita flavors. Palcohol's creator says it's a lightweight alternative for consumers who want to enjoy alcoholic drinks and avoid carrying around heavy bottles, but lawmakers have said it encourages underage drinking and could easily be concealed.
