Research Recommendations: Multidisciplinary Teams

1.	Cross-institutional collaborations integrating the expertise from a variety of different fields are needed to uncover cause-and-effect relationships.
2.	Given the rapidly evolving product landscape, streamlined timelines are essential, with the potential for rapid turnaround and response to changing epidemiologic patterns of vaping-associated lung injury.
3.	Identifying and clarifying approaches that allow researchers to study THC-containing products will be critical to enabling further progress toward identifying EVALI pathogenesis. Because many cannabis-associated products are prohibited by federal law, it is daunting for researchers to access and study these materials. Given this challenge, strategies to promote research in this area, such as changing federal restrictions on marijuana, THC, and CBD research, are essential to make any meaningful progress on establishing cause-and-effect relationships.
4.	Define combined pulmonary exposures (THC vaping plus conventional tobacco, etc.) and conduct studies modeling each combination for evidence of interactions and synergistic effects.

Definition of abbreviations: CBD = cannabidiol; EVALI = e-cigarette or vaping product use–associated lung injury; THC = tetrahydrocannabinol.
