Alcohol use among teens has dropped to historically low levels. In 2012, 3.6 percent of 8th graders, 14.5 percent of 10th graders, and 28.1 percent of 12th graders reported getting drunk in the past month, continuing a long-term, downward trend.. Significant declines include 5-year drops in daily alcohol use by 8th, 10th and 12th graders (0.3 percent, 1.0 percent and 2.5 percent, respectively, in 2012). In 2012, 23.7 percent of high-school seniors reported binge drinking (defined as 5 or more drinks in a row in the past 2 weeks)—a drop of one-quarter since the late 1990s.
