It looks like more college students are living the high life, literally. According to a recent survey, 38% of college students have used marijuana in the last year during 2015. This is a significant spike from the 30% of students who admitted to using marijuana back in 2006. Not only are more students smoking, but they appear to be smoking more often as well. One out of ever 22 students in the survey said that they would smoke 20 times a month or more, which breaks down to almost 5 days a week.
