Among emergency room patients, Budweiser is the king of beers.  Researchers at Johns Hopkins Bloomberg School of Public Health surveyed ER patients who'd been drinking alcohol before their visit and found Budweiser was the most common brand consumed.  Steel Reserve Malt Liquor, Colt 45, Bud Ice, and Bud Light rounded out the top five.  Approximately one-third of all ER visits in the U.S. involve alcohol consumption.
