description: The legalization of marijuana has emerged as a critical public policy issue, with far-reaching implications for health, education, and government programs at both the state and federal levels. The three essays of this dissertation show that medical marijuana legalization (MML) has a negative effect in each of these areas. The first essay shows, that the enactment of MMLs can exacerbate the crisis of overdose deaths in the United States. The study analyzes three key areas: the rate of overdose deaths caused by both legal and illegal drugs, the impact of MML on social norms regarding the perceived harm of marijuana, and an investigation into the gateway theory by examining the use of other addictive drugs. I find that MMLs increase deaths attributed to overdose by 21.5% population. MMLs s also indicate increase the number of deaths due to prescribed opioids by 44.6%, and deaths from all opioids (heroin and cocaine in addition to prescribed opioids) by 37.2 % Results suggest an overall increase in the use of marijuana, primarily due to lower perceived risk among adolescents. Additionally, results show an increase in hospital admissions due to substance abuse. The analysis suggests that legalizing medical marijuana may exaggerate the current problem of drug overdose in the United States. The second essay examines the impact of improved access to medical marijuana, measured by the proximity of schools to the nearest dispensary, on the academic performance of high school students in California. Students in schools farther from a marijuana dispensary have higher academic performance as measured through AP, ACT, SAT scores, and average GPA, and lower number of suspensions due to violence and illicit drug use. To show this, I construct the first geocoded dataset on marijuana dispensary and high school locations, use newly developed difference-in-differences estimators that rule out any bias due to heterogeneous treatment effects over time, and explore dynamic responses. This essay reveals the importance of ensuring a largest possible distance between schools and dispensaries to protect adolescents from the potential harm caused by medical marijuana. Finally, the third essay shows that in the long term, MMLs increase the number of disabled workers who receive Social Security Disability Income (SSDI) because of mental health issues. SSDI is a major social insurance program that provides benefits to workers who become disabled, and understanding how policy changes in other areas may impact this program is important. In this study, there were important differences between the results of a two-way fixed effects model and a new model by Callaway and Santa’Anna. MMLs, in theory, could either increase or decrease the number of SSDI recipients, and traditional fixed effects models suggest both could be at play; however, only the negative effect is robust to correction for heterogeneous effects. This highlights the need for future research to understand the true impact of medical marijuana legalization
