Adopting countries should coordinate evaluation so the evidence is undeniable.","summary":"Banning tobacco sales to anyone born after a set year, as the UK Tobacco and Vapes Bill does with a rising age of sale, could end smoking within a generation, so this idea forms an international consortium of adopting countries to pre-register outcome measures and evaluate the policy together. New Zealand repealed its version in 2024, so the evidence needs to be undeniable; age-of-sale laws such as Tobacco 21 in the US already reduce initiation, and a generational ban progressively removes the peer-supply loophole. Measures include smoking initiation by birth cohort, illicit market share and retail compliance. The test is a pre-registered synthetic-control evaluation. Being tested at scale, it addresses the bottleneck Prevention we already have is not deployed.","asOf":"2026-09-08","links":[{"label":"UK Tobacco and Vapes Bill (page moved; nearest live section)","url":"https://www.gov.uk/government/collections/"}],"tags":[],"related":[],"cancers":["nsclc"],"sections":["prevention"],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-prevention-adoption"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"A rising age of sale reduces smoking prevalence among the first affected birth cohorts by at least half relative to synthetic controls within five years.","rationale":"Age-of-sale laws already reduce initiation (Tobacco 21 in the US); a generational ban progressively removes the peer-supply loophole.","test":"Pre-registered synthetic-control evaluation.","maturity":"being-tested-at-scale","actor":"policy","cost":"small","horizonYears":6},"route":"/ideas/idea-prev-smokefree-generation-evaluation/","neighbours":{"cancer":[{"id":"nsclc","kind":"cancer","name":"Non-small-cell lung cancer","route":"/cancers/nsclc/"}],"section":[{"id":"prevention","kind":"section","name":"Prevention & Risk","route":"/fronts/prevention/"}],"bottleneck":[{"id":"b-prevention-adoption","kind":"bottleneck","name":"Prevention we already have is not deployed","route":"/bottlenecks/b-prevention-adoption/"}],"paper":[{"id":"paper-doll-hill-smoking-lung-cancer-bmj-1950","kind":"paper","name":"Doll and Hill 1950: the case-control study that tied smoking to lung cancer","route":"/key-papers/paper-doll-hill-smoking-lung-cancer-bmj-1950/"},{"id":"paper-doll-peto-50-year-doctors-bmj-2004","kind":"paper","name":"Fifty years of the British Doctors Study: smokers lose ten years of life, quitting gives most of it back","route":"/key-papers/paper-doll-peto-50-year-doctors-bmj-2004/"}],"idea":[{"id":"idea-nl-alcohol-minimum-pricing-cancer-endpoints","kind":"idea","name":"Evaluate alcohol minimum unit pricing against cancer incidence","route":"/ideas/idea-nl-alcohol-minimum-pricing-cancer-endpoints/"}],"roadmap":[{"id":"prevention-roadmap","kind":"roadmap","name":"Cancer prevention roadmap: tobacco control and vaccines → biomarker-guided chemoprevention → interception in carriers","route":"/roadmaps/prevention-roadmap/"}]}}
