Survey Finds More Students Are Using Pot Daily

A national survey by University of Michigan researchers has found that 5.9 percent of college students used marijuana on a daily or near-daily basis in 2014. (Daily or near daily is defined as 20 or more times in the past 30 days.) This level of pot use is up from 3.5 percent in 2007. In addition, the study found that 21 percent of students reported using pot at least once in the last 30 days.

The study also found that 39 percent of students used any illicit drug (including marijuana) in the last 12 months. That figure for 2014 is down slightly from 41 percent the year before but up from 34 percent in 2006. Most of the gain from 2006 on was in the use of pot.
