Daily Marijuana Use Among College Students Reaches 30-Year High

The percentage of U.S. college students who say they smoke marijuana daily or nearly every day is at its highest in more than three decades, according to a new survey. In 2014, 5.9 percent of college students said they smoked marijuana 20 or more times in the prior month. In fact, in 2014, near-daily use of marijuana was more common than daily cigarette use for the first time, the researchers found.
