Abstract

Background In 2015, almost one-fifth of English adults continued to smoke. Tobacco control policies in the UK are amongst the strongest in Europe, yet smoking prevalence remains stubbornly high, especially in deprived groups. Novel and radical approaches may be needed to control tobacco effectively. The British Medical Association backs a tobacco ban for those born after 2000, and a population-wide tobacco ban has already been implemented in Bhutan. We use microsimulation modelling to quantify the effectiveness and equity of these two radical tobacco policies.Methods IMPACTNCD is a previously validated dynamic stochastic microsimulation developed in R. It simulates the life course and smoking histories of synthetic individuals under alternative scenarios. We used IMPACTNCD to estimate the potential impact of two proposed changes to tobacco control policy in England – a sales ban restricted to those born in or after 2000 and a total sales ban – on a simulated English population over a 30 year time frame. Extrapolating from Bhutan’s implementation, we assumed 50% reductions in smoking initiation rate, active to ex-smoking ratio, and cigarette consumption. We compared both scenarios with a counterfactual that assumed current declining trends in smoking will continue in the future. We conducted a rigorous sensitivity analysis using second-order Monte Carlo simulation, and we report the median and interquartile range of the output distributions.Results The model suggested that under the tobacco-free generation caps scenario, smoking prevalence would fall to 12.4% (12.1% to 12.6%) for men and 7.9% (7.7% to 8.1%) for women, by 2045. This could prevent or postpone approximately 3500 (-4,200 to 11,000) cardiovascular disease cases and some 230 (-3,100 to 3,600) lung cancer cases; resulting in approximately 190 (-2900 to 3400) fewer cardiovascular disease deaths, and 220 (-2,700 to 3,200) fewer lung cancer deaths. Under the total caps scenario, the English smoking prevalence would fall to 7.2% (7.0% to 7.4%) for men and 4.3% (4.1% to 4.5%) for women, by 2045. This could prevent or postpone approximately 90,000 (70,000 to 120,000) cases of cardiovascular disease, some 79,000 (55,000 to 120,000) cases of lung cancer, approximately 14,000 (3,000 to 25,000) fewer cardiovascular disease deaths and some 54,000 (38,000 to 73,000) fewer lung cancer deaths. Both scenarios could reduce socioeconomic health inequalities in cardiovascular disease and lung cancer morbidity and mortality.Conclusion Strengthening existing English tobacco control policies through limiting access could substantially improve effectiveness and equity. Further research is now needed to explore the political and legal feasibility issues.
