New research shows that states with legal recreational cannabis had fewer cases of lung injuries related to vaping than other states, according to a study published by JAMA Network Open on Monday. The researchers found no significant difference in the number of e-cigarette or vaping associated lung injury (EVALI) cases in states with legal medical marijuana compared to prohibition states.
To conduct the study, researchers conducted an analysis of data from the Centers for Disease Control and Prevention (CDC) on EVALI cases at the state level, including Washington, D.C. The data was evaluated in conjunction with population figures and information on the prevalence of e-cigarette use for each state.
The study revealed that states with legal recreational marijuana dispensaries had 1.7 cases of EVALI per million people while states that prohibit adult-use cannabis had 8.1 cases per million. States that have only legalized medical marijuana saw 8.8 EVALI cases per one million residents, which while higher than prohibition states was not statistically significant.
“The data suggest that EVALI cases were concentrated in states where consumers do not have legal access to recreational marijuana dispensaries,” the study’s authors wrote. “This association was not driven by state‐level differences in e‑cigarette use, and
