Students also manifest 50 percent lower chance to pursue a university degree. In worse cases, marijuana smokers tend to simply stop their high school education, Press reader stressed. According to the School of Public Health and Health Systems professor Scott Leatherdale, the study signifies the importance of delaying the students' initiation to marijuana smoking.

The problem is with regular marijuana smoking which results to reduced neural development. Marijuana smokers tend to have an "inferior" memory, learning, and inhibitions, according to Science Daily. Lead author and post-doctoral fellow Karen Patte said that it is alarming that teenagers and young adults don't really perceive the harmful effects of marijuana smoking. This calls for a renewed focus on government regulations. Patte also stressed that promoting a healthy transition from youth to adulthood is a sufficient reason to look deeper at the looming marijuana legalization.
