Estimation of the global number of e-cigarette users in 2020.

Introduction:
This text provides an analysis of the regulatory landscape for e-cigarettes and heated tobacco products (hTPs) in various countries. The authors examine the regulatory approaches towards these products and assess their impact on public health. They also highlight the need for a balanced regulatory framework that encourages harm reduction while protecting public health.

Key Points:

* The authors conducted a comparative analysis of e-cigarette and hTP regulations in 12 countries.
* They found that while some countries have adopted a risk-proportionate regulatory approach, others have implemented strict regulations that may limit the potential benefits of these products in reducing harm from smoking.
* The authors argue that a balanced regulatory framework should consider the potential benefits of e-cigarettes and hTPs in reducing harm from smoking while ensuring their safety and preventing their uptake by non-smokers, particularly young people.
* They highlight the importance of evidence-based regulation and the need for regulators to monitor and evaluate the impact of regulations on public health.
* The authors also emphasize the need for international cooperation and harmonization of regulations to ensure that they are proportionate to the risks and benefits of these products.

Main Message:
The text highlights the importance of a balanced regulatory framework for e-cigarettes and hTPs that considers their potential benefits in reducing harm from smoking while ensuring their safety and preventing their uptake by non-smokers. The authors emphasize the need for evidence-based regulation and international cooperation to ensure that regulations are proportionate to the risks and benefits of these products. Overall, the text underscores the need for a nuanced and balanced approach to regulating e-cigarettes and hTPs to maximize their potential for harm reduction while minimizing their potential risks.
