Abstract (English):	Objectives. To assess how and in what extent the electronic nicotine delivery systems (ENDS) use substituted the consumption of traditional combustible cigarettes (c-cigarettes, c-cig). Materials and Methods. We performed a systematic review of the literature up to August 2019 in scientific databases. Primary outcomes were proportion of complete or partial substitution of conventional to electronic cigarettes and related economic aspects. Secondary outcomes were odds ratio of substitution and country-wise time trends. Results. We retrieved 3,628 references and included 49 studies, providing economic and epidemiological data. Economic studies of cross-price elasticity showed that combustible cigarettes are partially substitutable for electronic cigarettes. Most studies reported that electronic cigarettes consumption prevalence increased over time. Three studies reported a significant reduction of combustible cigarettes consumed per day among dual users (combustible-plus electronic-cigarettes users) versus combustible-cigarettes users. The pooled adjusted odds ratio of quitting combustible cigarettes among electronic cigarettes users versus never or past electronic cigarettes (e-cigarettes, e-cig) users was 1.19 (95% confidence interval 1.09 to 1.30; heterogeneity score 0%). Longitudinal studies showed globally a growing prevalence of electronic cigarettes use, mainly in adolescents. A negative relationship between consumption and price increase of electronic and combustible cigarettes was found. Conclusion. The chance of quitting smoking combustible cigarettes among current electronic nicotine delivery systems users was increased with respect to never- or pastelectronic nicotine delivery systems users. Economic studies reported that electronic cigarette is partially substitutable for combustible cigarettes. [ABSTRACT FROM AUTHOR]
Abstract (Spanish):	Objetivos. Evaluar cómo y en qué medida se produce un intercambio desde los cigarrillos convencionales (CC) a los sistemas electrónicos de administración de nicotina (SEAN). Materiales y métodos. Se realizó una revisión sistemática hasta agosto de 2019. El desenlace primario fue la proporción de un intercambio completo o parcial de CC a los SEAN y sus aspectos económicos. Los desenlaces secundarios como medidas de resultado fueron la probabilidad de intercambio y la tendencia en el intercambio por países. Resultados. Se encontraron 3628 referencias y se incluyeron 49 estudios con datos epidemiológicos y económicos. Los estudios económicos sobre la elasticidad cruzada de precios mostraron que los CC son parcialmente intercambiables por SEAN. La mayoría de los estudios reportaron que la prevalencia del consumo de cigarrillos electrónicos se incrementó con el tiempo. Tres estudios reportaron una reducción significativa de los CC consumidos por día entre fumadores duales (convencionales más SEAN) en comparación con los consumidores de CC. El odds ratio ajustado y combinado de dejar los CC entre consumidores de SEAN en comparación con quienes nunca consumieron o lo hicieron en el pasado fue de 1,19 (IC95%: 1,09-1,30; heterogeneidad 0%). Los estudios longitudinales mostraron una creciente prevalencia del uso de cigarrillos electrónicos, principalmente en adolescentes. Se encontró una relación negativa entre el consumo y aumento de precio de CC y electrónicos. Conclusión. La probabilidad de dejar de fumar CC entre consumidores habituales de SEAN se incrementó respecto a los consumidores que nunca o que solían consumir SEAN. Estudios económicos reportaron que los cigarrillos electrónicos son parcialmente intercambiables por los CC. [ABSTRACT FROM AUTHOR]
