ELFBAR: What tobacco harm reduction means for Germany's health system

200,000 synthetic individuals3 scenarios2026 to 2040Report in German and English

Situation

ELFBAR, one of the world's largest providers of alternative nicotine products, needed robust evidence on the health and economic effect of smokers in Germany switching to less harmful products. A question where every number gets politically scrutinised.

Approach

Socio economic microsimulation of 200,000 synthetic individuals modelled on German demographics, smoking prevalence, disease risks and healthcare costs. Validated through expert interviews in pharmacology, addiction research and statutory health insurance, international benchmarks from the UK, Sweden and New Zealand, sensitivity analysis and academic quality assurance by IU International University.

Result

Savings in direct healthcare costs from 2026 to 2040: approx. €15bn pessimistic, €48bn realistic, €75bn optimistic. Plus measurable gains in quality adjusted life years and concrete policy recommendations. Report in German and English.

Impact: a reference study in Europe. First presented at a closed policy roundtable in Berlin, co hosted with IU International University of Applied Sciences, to decision makers from politics, health insurance and academia. Study lead Dominic Multerer, with Prof. Dr. Florian Hummel (IU) and Dr. Bernhard Schropp (microsimulation).Read the study (PDF, German) Published by ELFBAR
