Daily marijuana use among U.S. college students is rising, and, for the first time since data have been collected, their use of pot has surpassed cigarette smoking, according to a new national survey. In 2014, 5.9 percent of college students were smoking marijuana daily or near-daily. That compares with 3.5 percent in 2007. Researchers conducting the University of Michigan's Monitoring the Future study theorized that much of the increase may be due to the fact that public perception of the dangers of marijuana use has shifted dramatically in recent years with its legalization in a growing number of jurisdictions.
