Association of State Marijuana Legalization Policies for Medical and Recreational Use With Vaping-Associated Lung Disease

Author Insights: Bariatric Surgery May Lead to Increases in ...“From June 2019 to January 2020, over 2500 cases of electronic cigarette (e-cigarette)– or vaping–associated lung injury (EVALI) were reported to the Centers for Disease Control and Prevention (CDC).

Some states have legalized marijuana and THC-containing products for recreational use. Many other states allow purchases for qualifying medical purposes. In remaining states, all forms of consumption and distribution are illegal, and individuals who use THC likely obtain it from the black market. If black-market THC products are responsible for EVALI, then case rates may be lower in recreational marijuana states.

The goal of this cross-sectional study was to measure whether states where marijuana is legal have lower rates of EVALI compared with states where it is illegal.

Recreational marijuana states had among the lowest EVALI rates of all states.

The data suggest that EVALI cases were concentrated in states where consumers do not have legal access to recreational marijuana dispensaries. This association was not driven by state-level differences in e-cigarette use, and EVALI case rates were not associated with state-level prevalence of e-cigarette use.

One possible inference from our results is that the presence of legal markets for marijuana has helped mitigate or may be protective against EVALI.”
