NW grocery chain pulls Four Loko drinks off shelves

Pressure on makers of caffeinated alcohol drinks is mounting as a Northwest grocery chain announced Tuesday it is pulling the products from its shelves, and a Tacoma legislator said she hopes to make another attempt to ban the beverages in the state.

Meanwhile, a spokesman for the U.S. Food and Drug Administration, which last year threatened to ban the beverages unless producers prove their safety, said the agency is "working vigorously" to determine whether the drinks should remain on the market.
