Kansas liquor officials are telling retailers to pull Four Loko and other alcoholic energy drinks from their shelves.
The state Department of Alcoholic Beverage Control said it rescinded approval of all alcohol energy drinks. Suppliers and distributors of alcohol energy drinks are being notified through issuance of an order by ABC director Tom Groneman.
The department says it based its decision in part on a recent U.S. Food and Drug Administration declaration that the drinks aren't safe.
On Nov 17, 2010, the FDA found that caffeine is not safe when added to alcoholic liquor and warned manufacturers of such alcoholic energy drinks to immediately correct the situation.
The ban on sale and distribution affects four products: Four Loko, Four Maxed, Joose and Max, the agency said.
A typical alcohol energy drink is 24 ounces and has 12 percent alcohol content, or almost 3 to 4 times the alcohol content of a 12 ounce beer, it said.
"The Division's concern for the health, safety and welfare of Kansas citizens along with the FDA's recent ruling validate that these products should no longer be on Kansas shelves," Groneman said in a statement.
Some officials have warned that caffeine and other stimulants lacing the beverages encourage binge drinking by preventing consumers from realizing how drunk they might be.
Several states already have banned the drinks.
