Four completely different kinds of evidence that vaping increases adult smoking cessation

While a contentious debate persists within the tobacco control community as to whether vaping decreases cigarette smoking, those supporting the affirmative side of the debate have the unusual good fortune of being able to draw on four completely different kinds of evidence in support of their position. These include (i) randomized controlled trials, (ii) population studies (including analyses of population-wide aggregated data and individual-level survey data); (iii) market behavior (including cigarette and e-cigarette sales data and stock market reactions); and (iv) economic studies finding that vaping and cigarette smoking are substitutes (some noting unintended adverse consequences of policies intended primarily to reduce youth vaping). This presentation will highlight the implication of having such diverse types of evidence all sharing the same conclusion about vaping’s impact on smoking cessation. Additionally, the presentation will examine the strengths and limitations of these bodies of evidence
