Thirty-six states have legalized medical marijuana and 14 states have legalized the use of marijuana for recreational purposes. In this paper, we review the literature on the public health consequences of legalizing marijuana, focusing on studies that have appeared in economics journals as well as leading public policy, public health, and medical journals. Among the outcomes considered are: youth marijuana use, alcohol consumption, the abuse of prescription opioids, traffic fatalities, and crime. For some of these outcomes, there is a near consensus in the literature regarding the effects of medical marijuana laws (MMLs). As an example, leveraging geographic and temporal variation in MMLs, researchers have produced little credible evidence to suggest that legalization promotes marijuana use among teenagers. Likewise, there is convincing evidence that young adults consume less alcohol when medical marijuana is legalized. For other public health outcomes such as mortality involving prescription opioids, the effect of legalizing medical marijuana has proven more difficult to gauge and, as a consequence, we are less comfortable drawing firm conclusions. Finally, it is not yet clear how legalizing marijuana for recreational purposes will affect these and other important public health outcomes. We will be able to draw stronger conclusions when more post-treatment data are collected in states that have recently legalized recreational marijuana.

The Public Health Effects of Legalizing Marijuana

BACKGROUND AND OBJECTIVES
Eight states and Washington, DC have implemented regulations mandating a minimum ratio between treatment staff and patients receiving hemodialysis in a facility in an effort to improve the quality of hemodialysis treatment. Our investigation examines the association between minimum staffing regulations and patient mortality for four states and hospitalizations for two states that implemented these rules during our sample period.


DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS
We utilized a synthetic difference in differences estimation to analyze the effect of minimum staffing ratios on hemodialysis treatment quality, measured by deaths and hospitalizations for end-stage renal disease patients. We used data gathered by the US Renal Data System and aggregated at the state level.


RESULTS
We are unable to find evidence that mandated dialysis staffing ratios area associated with a reduction in mortality or hospitalizations. We estimate a slight reduction in deaths per 1000 patient hours and a slight increase in hospitalizations, but neither are statistically significant.


CONCLUSIONS
We were unable to find evidence that minimum staffing ratios for hemodialysis facilities are associated with improved patient outcomes. Our findings highlight the need for future work, studying the impact of these regulations at the facility level.

Estimating the effect of dialysis staffing ratio regulations on mortality and hospitalizations for Medicare hemodialysis patients.


Background. We extend the model introduced by Anderson et al. [M.D. Anderson, D.I. Rees, J.J. Sabia, American Journal of Public Health 104, 2369-2376] to evaluate the public mental health implications of new developments in marijuana policy, such as recreational marijuana access and additional years of data on suicide mortality.

Methods. We obtained state-level suicide data from the National Vital Statistics System9s Mortality Detail Files for 1999-2018. We used panel regression analysis to examine the association between suicides per 100 000 population and both medical and recreational marijuana access. Three specifications of the equation were employed as a robustness test.

Results. After adjusting for economic conditions, alcohol taxes and consumption, time effects, state fixed effects, and state-specific linear time trends, the legalization of recreational marijuana was associated with a 2.9% (95% confidence interval [CI] = -5.6, -.03) reduction in the suicide rate for the most rigorous specification, but didn9t pass the robustness check at the P < .05 level for the other two specifications. However, recreational marijuana legalization was associated with a 5.4% reduction (95% CI = -9.4%, -1.4%) in suicide rates for males in the 40 to 49 age group, passing the robustness check for all specifications.

Conclusion. Suicide rates among men in the 40 to 49 age group fell after recreational marijuana legalization compared with those in states that did not legalize, which is consistent with the results found by Anderson et al. for medical marijuana when that same population was younger.
There was no consistent relationship between medical marijuana legalization and suicide rates for any population. Additionally, mental health indicators at the state level were unaffected by either recreational or medical marijuana legalization. We confirm the findings of Anderson et al. (2014), observing no consistent relationship between marijuana legalization and observable mental health outcomes. However, suicide rates increase at lower rates on average relative to other states following recreational marijuana legalization.

The Relationship Between Cannabis Legalization, Suicide and Mental Health Remains Unchanged After Recreational Access

BACKGROUND AND OBJECTIVES In 2005, the New Jersey Department of Health enacted a rule requiring that an administrator or designate always be present in a hemodialysis clinic and that the individual may not be involved in patient care activities at any time. Our investigation examines the effect of this unique rule on patient mortality and hospitalizations and is meant to inform the public policy discussion. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS We utilized a synthetic control estimation to analyze the effect of this rule on patient mortality in New Jersey. We also compared trends for hospitalizations in New Jersey to other similar states. RESULTS We find no evidence that the law affected patient mortality or the number of hospitalizations for Medicare patients in New Jersey. CONCLUSIONS The New Jersey law poses substantial costs to hemodialysis clinics and we find little evidence of any measurable benefit to patients.
