LINCOLN, Neb. (AP) — Nebraska could join six other states in banning powdered alcohol under a bill that won first-round approval in the Legislature.

Senators voted 32-3 Tuesday to advance a measure by Sen. Tyson Larson of O’Neill that would prohibit buying or selling of products that can be added to water to make an alcoholic drink.

The original bill combined a handful of liquor initiatives and would have given the Liquor Control Commission jurisdiction over powdered alcohol.

Sen. Mark Kolterman of Seward added an amendment Tuesday to ban the substance completely, saying he became concerned when the U.S. Alcohol and Tobacco Tax and Trade Bureau approved the product in March.

Opponents say the effects of powdered alcohol have not been tested and could encourage underage drinking.
