Marijuana: 4 Hidden Costs to Consider

Marijuana

“Opportunity cost: Something a person sacrifices when they choose 1 option over another” (1).

For students, the health impact of marijuana use may be understated, and its harms can be sneaky. Beyond the cost of purchase, what is marijuana use costing you?

Hidden cost #1: Your total time in school
If you use marijuanna 2 or more times per month, you may be 66% more likely to miss 1 or more semesters of class (2): This was shown in a study of 1,133 students over a 4 year time period, starting freshman year, even after adjusting for variables such as demographic characteristics, high school GPA, fraternity/sorority involvement, personality/temperament characteristics, nicotine dependence, and alcohol use disorder (2).

Hidden cost #2: Your future income
6 years after graduation, students who used marijuanna infrequently during college were 3.7 x more likely to be unemployed than non-users (3).

Hidden cost #3: Your ability to study
The use of Marijuanna 4 or more times per month may impair brain functioning.
In this study, students demonstrated poorer verbal learning (p<.01), verbal working memory (p<.05), and attention accuracy (p<.01) compared to non users (4).
This might translate to more time studying or less information learned, mistakes, more frustration and angst with school work; and poor academic performance.

Hidden cost #4: Your emotional health
The cost of missing/prolonging school, poor grades due to marijuanna use, reduction in future and current income (money spent on marijuanna could be used for other things), fear of getting caught, and potential legal consequences are all stressful consequences beyond the biological impact of marijuanna use. Is it worth the extra stress?
Biologically, marijuanna can impact depression; while depression can impact marijuanna use (5).
If you can relate to any of this, you may want to ask yourself… Are these costs worth it?
How much better would your life be if you instead addressed your depression, anxiety, stress/time management skills, in healthier ways like counseling, exercise, meditation, improving medical health, etc?
