“…To the extent that ENDS use, especially exclusive use trends continue, the impact of eliminating Mexico's ENDS ban is likely to be less than projected by our estimates because those likely to use ENDS may have already become regular users. Currently, ENDS use occurs predominantly among individuals who concomitantly use cigarettes (80% of males and 90% of females who use ENDS in 2021) (85), while the prevalence among never tobacco users is very low (31), indicating that the ban may have discouraged smokers from switching entirely to ENDS use, potentially due, at least partially, to the lack of legally available products and current cigarette policies. SAVM follows a conservative approach and does not distinguish dual use from exclusive smoking and assumes the same cessation and switching patterns and health risks among dual users as among exclusive smoking (86,87).…”

Objective To develop the Mexico Smoking and Vaping Model (Mexico SAVM) to estimate cigarette and electronic nicotine delivery systems (ENDS) prevalence and the public health impact of legalizing ENDS use. Methods SAVM, a cohort-based discrete-time simulation model, compares two scenarios. The ENDS-Restricted Scenario estimates smoking prevalence and associated mortality outcomes under the current policy of an ENDS ban, using Mexico-specific population projections, death rates, life expectancy, and smoking and e-cigarette prevalence. The ENDS-Unrestricted Scenario projects smoking and vaping prevalence under a hypothetical scenario where ENDS use is allowed. The impact of legalizing ENDS use is estimated as the difference in smoking- and vaping-attributable deaths (SVADs) and life-years lost (LYLs) between the ENDS-Restricted and Unrestricted scenarios. Results Compared to a national ENDS ban, The Mexico SAVM projects that legalizing ENDS use could decrease smoking prevalence by 40.1% in males and 30.9% in females by 2049 compared to continuing the national ENDS ban. This reduction in prevalence would save 2.9 (2.5 males and 0.4 females) million life-years and avert almost 106 (91.0 males and 15.5 females) thousand deaths between 2025 and 2049. Public health gains decline by 43% to 59,748 SVADs averted when the switching rate is reduced by half and by 24.3% (92,806 SVADs averted) with a 25% ENDS risk level from that of cigarettes but increased by 24.3% (121,375 SVADs averted) with the 5% ENDS risk. Conclusions Mexico SAVM suggests that greater access to ENDS and a more permissive ENDS regulation, simultaneous with strong cigarette policies, would reduce smoking prevalence and decrease smoking-related mortality. The unanticipated effects of an ENDS ban merit closer scrutiny, with further consideration of how specific ENDS restrictions may maximize public health benefits.

“…Las asociaciones encontradas son relevantes pues en un estudio reciente de Zavala-Arciniega et al (2021), se encontró que los usuarios mexicanos con patrón de consumo dual (cigarro-e y cigarro convencional) tuvieron un perfil de riesgo más elevado dado que presentaban mayor dependencia al cigarro. Por otro lado, se sabe ampliamente que el consumo de cigarros convencionales depende de una gran cantidad de factores, por ejemplo, Ferrel et al (2016) resaltan algunos de tipo psicosocial que incluyen la presión social, una familia disfuncional y la falta de habilidades sociales.…”

La economía conductual evalúa la eficacia relativa de reforzamiento de nicotina mediante tareas de compra hipotética de cigarros. Esta variable es considerada una diferencia individual que predice cambios en el consumo a lo largo del tiempo. Una curva de demanda de cigarros clasifica el grado en que el consumo es insensible al incremento del precio (elasticidad), así como la interacción entre productos cualitativamente distintos como el cigarro convencional y cigarro electrónico. Se administraron tareas de compra a 38 fumadores que consumían en promedio ocho cigarros por día, se examinó el nivel de ajuste del consumo de cigarros al modelo exponencial de la demanda. Se evaluaron los productos por separado y la demanda cruzada. El promedio de cigarros reportado mostró un adecuado ajuste al modelo exponencial (R2 = .99). La demanda cruzada de cigarros electrónicos fue de 0.0026 (sustitución), sin embargo, no fue significativa. Los índices de demanda fueron predictores del patrón de consumo y puntaje de dependencia a la nicotina. Se concluyó que la preferencia de cigarros electrónicos depende de su disponibilidad y precio en relación con los cigarros convencionales. Los índices de demanda son variables importantes para el entendimiento del consumo de sustancias y el mantenimiento de la adicción.

“…There is limited work that has attempted to identify the correlates of dual use of cigarettes and e-cigarettes. 19 - 21 One study found that depressive symptoms and adverse childhood experiences (ACEs) were associated with all trajectories of dual use. 19 Piper et al found that dual users were more likely to be younger and white and did not differ in their intentions to quit smoking.…”

Many Canadians use nicotine products such as cigarettes and e-cigarettes. A particular subpopulation of concern is post-secondary students given they have a higher prevalence of use. Many correlates of cigarette smoking and e-cigarette use have been identified. However, less focus has been on examining the correlates of cigarette smoking, e-cigarette use and dual use. This study explores the correlates of different nicotine modality use in post-secondary students. Using data from the Canadian Campus Wellbeing Survey (CCWS; n = 27,164), a multi-level nominal regression assessed the correlates of nicotine modality use. In comparison to individuals who were <20, individuals 20-24 (OR = .448, 95% CI .321, .625), 25-29 (OR = .140, 95% CI .093, .212), 30-34 (OR = .076, 95% CI .046, .125) and over 35 (OR = .041, 95% CI .024, .071) had lower odds of e-cigarette use compared to cigarette smoking. Identifying as a woman (OR = 1.553, 95% CI 1.202, 2.006), non-heterosexual (OR = .642, 95% CI = .485,0.851), current cannabis user (OR = 1.651, 95% CI 1.296, 2.104), and being an international student (OR = .350, 95% CI .251, .487) also impacted the odds of e-cigarette use vs only cigarette smoking. When considering dual use vs cigarette smoking, individuals aged 20-24 (OR = .491, 95% CI .337, .717), 25-29 (OR = .221, 95% CI .137, .357), 30-34 (OR = .163, 95% CI .091, .292) and over 35 (OR = .122, 95% CI .065, .230) had lower odds than individuals <20. Current cannabis use (OR = 1.680, 95% CI = 1.209, 2.138), binge drinking (OR = 1.885, 95% CI 1.384, 2.568), and international student status (OR = .689, 95% CI .476, .996) also impacted cigarette smoking vs dual-use. Overall, a minority of young adults (11.5%) at post-secondary institutions in our sample use nicotine products, and the higher prevalence of e-cigarette use warrants continued monitoring. Health promotion campaigns addressing e-cigarette use are required. Additionally, tailored intervention efforts could prioritize the treatment needs of international students studying in Canada.
