Does Regulation Change What People Believe About Nicotine? - Fernando Briseno

Movimiento Pro-Vecino conducts a multinational research project that investigates how regulatory environments influence public perceptions of nicotine risk. The study focuses on a key but often overlooked question: whether public beliefs about the risks of nicotine products are shaped not only by scientific evidence or public communication, but also by regulatory signals. Across many countries, a large share of the population believes that nicotine itself is the main cause of smoking-related disease. However, scientific evidence distinguishes clearly between the harms caused by combustion in cigarettes and the pharmacological effects of nicotine as an addictive substance. Despite decades of research and public health messaging, confusion about nicotine’s role remains widespread. This raises an important research question: how are these beliefs formed, and what factors influence them? One possible explanation is that regulation itself acts as a signal to the public. When products such as e-cigarettes are banned or heavily restricted, individuals may interpret these policies as evidence that such products are extremely harmful. However, there is very little causal evidence on how regulatory information affects risk perception. To address this gap, the project uses a randomized survey experiment conducted in three Latin American countries: Mexico, Argentina and Chile. Participants in the survey are randomly assigned to either a control group or a treatment group. The treatment group receives a brief informational card explaining the current regulatory status of vaping products in their country before answering the same questions. This design allows researchers to identify the causal effect of regulatory knowledge on perceived risk. For more information, visit: www.econhealthinsights.org and www.provecino.org.mx
