The number of U.S. college students smoking marijuana every day or nearly every day is greater than it has been in 35 years, according to a study released on Tuesday. Nearly 6 percent of college students reported using pot daily or near-daily in 2014, up from 3.5 percent in 2007 but less than the 7.2 percent recorded in 1980, the University of Michigan's Monitoring the Future study found. “It's clear that for the past seven or eight years there has been an increase in marijuana use among the nation's college students,” said Lloyd Johnston, the study's principal author.
