Status Enrolling by invitation

Clinical Trial Summary

Few countries have legislation to reduce the number and types of tobacco retail outlets. The Netherlands plans to ban tobacco sales in supermarkets in 2024. The overall aim of this proposed research is to evaluate the implementation of new legislation to reduce the number and types of tobacco outlets in the Netherlands, up until and including the ban on sales of tobacco in supermarkets.

In a comprehensive policy evaluation, the investigators plan to examine (1) the impact of the policy on the number and types of tobacco outlets, (2) the impact on attitudes and behaviors of smoking adults and non-smoking youth, and (3) the influence of the tobacco industry on the policy process and the retail environment. In addition, the investigators plan to focus on differential effects in disadvantaged neighborhoods, where both smoking rates and tobacco outlet density are typically highest.

The investigators bring together a unique combination of economic, psychological, and journalistic research methods. The investigators examine the impact of the new legislation on the amount and type of tobacco outlets and on the number of smokers by using routinely collected monitoring data. The investigators examine the impact of the legislation on smoking susceptibility of non-smoking youth and on impulse tobacco purchases by smoking adults with yearly quantitative surveys (two surveys before the policy implementation and two after) and with qualitative interviews and discussion sessions. The investigators examine whether these impacts differ for disadvantaged versus non-disadvantaged neighborhoods. The investigators examine what strategies the tobacco industry uses to influence the new legislation, policy processes, and the tobacco retail environment by performing a journalistic investigation, using for example documents obtained by Freedom of Information Act requests, (possibly) leaked documents from insider meetings, and interviews with insiders.

Our research will provide a comprehensive evaluation of the effects of the implementation of the proposed legislative measures. Based on our results, the investigators will formulate recommendations for the Dutch Cancer Society, the Dutch government, and for other countries who consider reducing the number of tobacco outlets; highlight potential areas for further development and improvement within the legislative framework and provide recommendations on how to counter the lobby from the tobacco industry.

Clinical Trial Description

Problem description: Tobacco use is the primary cause of several cancers; among them lung cancer, which is the leading preventable cause of death in the Netherlands. Yet, tobacco use remains high in the Netherlands, with an adult smoking prevalence of 20%, which is even higher in groups with a lower socioeconomic position. Therefore, reducing the smoking prevalence in all groups in society is one of the three priorities in the Dutch National Prevention Agreement. This Agreement was made with the Dutch government and more than 70 societal organizations, including the Dutch Cancer Society. It consists of a range of voluntary agreements and policy measures to reduce smoking prevalence to 5% or less by 2040. Among these measures is the proposal to reduce the number of outlets that sell tobacco. The government has announced a stepwise approach to ban the sales of tobacco products from various types of outlets. The first step is planned for 2022, with a ban on cigarette dispensing machines. This is followed by a ban on the online sale of tobacco in 2023. In 2024, the largest change is planned with a ban on the sales of tobacco for supermarkets, which currently accounts for approximately 40% of tobacco outlets in the Netherlands. The last step is to phase out the sale of tobacco at petrol stations and convenience stores, so that in the end only specialist tobacco shops can sell tobacco products. The reasoning of the Dutch government for this legislation is to protect young (non-)smokers and adult (former) smokers from exposure to tobacco products and with that from the temptation to smoke and to make impulse purchases, ultimately making it easier to quit smoking and less likely to (re-)initiate smoking. It also adds to the denormalization of smoking as it makes tobacco products disappear from common sight. The proposed measures however lack clear goals, such as a target number of tobacco outlets, nor is there any particular attention given to reducing socioeconomic inequalities in smoking through these measures. Moreover, the tobacco industry is known to try to stop, delay, or weaken legislation before it is implemented, and may try to influence the tobacco retail environment.

Research direction: The investigators will do a comprehensive policy evaluation of the new Dutch legislation on tobacco outlets. The investigators examine:

• The effects of the legislation on the number of tobacco sales outlets.

• The effects of the reduced number of sales outlets (if any) on the number of smokers.

• The effects on smoking susceptibility among non-smoking youth.

• The effects on impulse tobacco purchases of smoking adults.

• How these impacts differ for those living in disadvantaged versus non-disadvantaged neighborhoods.

• The strategies that the tobacco industry uses to influence the national legislation on tobacco outlets.

• And the strategies that the tobacco industry uses to influence the tobacco retail environment in the Netherlands.

Aim: The overall aim of this proposed research is to evaluate the implementation of new legislation to reduce the number and types of tobacco outlets in the Netherlands, up until and including the ban on sales of tobacco in supermarkets.

Primary research questions are:

What is the impact of the new legislation on the number and type of tobacco outlets? What is the impact of the new legislation by supermarkets on the number of smokers? What is the impact of the new legislation on smoking susceptibility of non-smoking youth? What is the impact of the new legislation on impulse tobacco purchases by smoking adults? Does this impact differ for smoking adults living in disadvantaged versus non-disadvantaged neighborhoods? What strategies does the tobacco industry use to influence the new legislation and policy processes? What strategies does the tobacco industry use to influence the tobacco retail environment?

Secondary research questions are:

How do non-smoking youth and smoking adults experience the new legislation? To what extent does the new legislation lead to more illegal (online) sales of tobacco and what is the role of the tobacco industry in this? What is the impact of the new legislation on use and marketing of 'reduced risk' products such as electronic cigarettes and heated tobacco?

Expected outcome: Our research will provide a comprehensive evaluation of the effects of the implementation of the proposed measures on the reduction of tobacco outlets. The four organizations that carry out this research have worked closely together in the past on comparable research projects and will ensure that the three parts of the project will come together to provide a comprehensive picture. Based on our results, the investigators will formulate recommendations for the Dutch Cancer Society, the Dutch government, and for other countries who consider reducing the number of tobacco outlets. The investigators will highlight potential areas for further development and improvement within the legislative framework and provide recommendations on how to counter the lobby from the tobacco industry.

Plan of Investigation:

The proposed research consists of three parts:

1. In the first part, the investigators examine the effects of the legislation on the number of tobacco sales outlets. The investigators also study the effects of the reduced number of sales outlets (if any) on the number of smokers. Both are examined separately for disadvantaged and non-disadvantaged neighborhoods. For this work package the investigators rely on existing data on retail locations and smoking prevalence. The investigators use data from 2018 to 2025 to account for existing trends. This part will be carried out by a research institute that specializes in economic analyses (SEO Amsterdam Economic) sand has done previous analyses with sales outlet and smoking prevalence data.

2. In the second part, the investigators examine the effects of the legislation on smoking susceptibility among nonsmoking youth and on impulse tobacco purchases of smoking adults. The investigators also examine how the effects differ for smoking adults living in disadvantaged versus non-disadvantaged neighborhoods. The investigators will conduct yearly, quantitative survey waves from 2022 to 2025 among a cohort of 250 non-smoking youth, 600 smoking adults from disadvantaged neighborhoods, and 600 smoking adults from non-disadvantaged neighborhoods. The investigators will also carry out in-depth qualitative interviews and discussion sessions with non-smoking youth and smoking adults from these three groups. This part will be carried out by a research institute that specializes in mixed-methods addiction research (IVO research Institute) and focuses on vulnerable groups in society, together with a university department of Health Promotion (Maastricht University) that has ample experience with tobacco control policy evaluations.

3. In the third part, the investigators examine the strategies of the tobacco industry to influence both the national legislation on tobacco outlets, and to influence the tobacco retail environment. The investigators use investigative journalism techniques to uncover lobbying strategies and tactics of the tobacco industry and their allies. The investigators use a wide range of sources: documents obtained by FOIA-requests, (possibly) leaked documents from insider meetings, (background) interviews with insiders of the tobacco industry, the government, and the retail sector, the analysis of social media campaigns, financial and marketing data, and observations of tobacco outlets (online and offline). This part will be carried out by an organization of investigative journalists that specializes in the strategies and tactics of the tobacco industry (The Investigative Desk). ;
