Marijuana is even riskier today because so much of the marijuana on the market is grown indoors and bred for specific qualities, like potency. This means that most of the marijuana that students smoke today is much stronger than it was for their parents’ generation. The average THC level rose from less than 1% in the late 1970s to more than 10% in 2008, and greater today.(some say as high as 30%)

The accuracy of The Princeton Review's rankings has also been questioned, especially with regards to the larger schools. Experts argue that the sample size of students surveyed at each college (three hundred students, on average) is not enough to provide a truthful depiction of student behavior. "It's positively unscientific," said Dr. Henry Weschler of the Harvard School of Public Health College Alcohol Studies Program.
