Any time college students are polled, the results should always be taken with a heavy grain of salt. Sample sizes and survey sampling often skews data involving subjects admitting drug use.
For instance, in this case, I find it impossible that only 32.3% of college students have “tried” smoking weed. The Infographic does, however, enforce the main tenet of legalization: that alcohol and prescription drugs are far more dangerous than cannabis.
