The Future of Nicotine Research: What We Most Need to Know
What are the most urgent unanswered questions in nicotine science? A research agenda for the next decade, organized by the questions whose answers would most affect policy and practice.
The nicotine research agenda for the next decade is not a list of every unanswered question. It's a prioritized set of questions whose answers would most affect policy and practice. Here are the most urgent: What are the long-term health effects of daily vaping over decades? (Answerable through long-term cohort studies of vapers, with careful control for past smoking.) What is the net population effect of flavor restrictions on smoking and vaping rates? (Answerable through rigorous policy evaluation using quasi-experimental methods.) How effective are nicotine pouches for smoking cessation compared to vaping and NRT? (Answerable through randomized trials.) What are the health effects of chronic nicotine pouch use over decades? (Answerable through long-term cohort studies, ideally in Sweden where oral nicotine use is established.)
How can risk information about nicotine products be communicated to maximize informed choice while minimizing youth initiation? (Answerable through communication experiments and real-world messaging trials.) What are the effects of differential taxation of nicotine products on switching behavior and population health? (Answerable through natural experiments in jurisdictions that implement differential tax structures.) How can smoking cessation be integrated into mental health, substance use, and chronic disease care? (Answerable through implementation science and health-services research.) What are the most effective strategies for preventing youth nicotine initiation in an environment of rapidly evolving products and marketing channels? (Answerable through prevention-intervention trials and policy evaluation.)
These questions are all answerable with current methods. The barriers are not scientific but institutional: the funding, the data access, and the political will to ask and answer them. The research agenda is clear. What's needed is the investment to execute it.
