The Royal College of Physicians Report on E-cigarette Use

According to a report released by the Royal College of Physicians (RCP) on April 23, e-cigarettes are an effective aid for quitting smoking. However, more measures should be taken to reduce the appeal, availability, and affordability of e-cigarettes to non-smokers, as well as minimize their impact on the environment.

The results were summarized into over 50 recommendations, which explored trends in the use of combustible tobacco and e-cigarette products, differences in the health impacts of e-cigarettes on smokers, non-smokers, or both, as well as environmental damage, and the role of e-cigarette use in the expansion of the tobacco industry.

The conclusion of the RCP report is that since the 2016 RCP report, the evidence of the effectiveness of e-cigarette-assisted smoking cessation has become stronger. In recent years, there has been a significant increase in the number of young people and non-smokers using e-cigarettes, so timely remedial measures are needed to curb youth e-cigarette use while not affecting the use of e-cigarettes as a smoking cessation aid for adults. The government should commission regular updates on the evidence of the use and impact of nicotine products to guide policies.

Researchers emphasize that e-cigarettes should be promoted as an effective tool to help smokers quit smoking, particularly focusing on those who stand to benefit the most, such as individuals with mental health disorders or those in socioeconomically disadvantaged positions, or living in social housing.

Researchers reviewed the potential adverse effects of using e-cigarette products on health by examining biomarkers of e-cigarette exposure and harm from data released between 2021 and 2023. They compared e-cigarette users, smokers, dual users (both using e-cigarettes and smoking), and non-users of both products.

Although harmful substance levels of e-cigarette users are found to be lower than smokers in many biomarker analyses, researchers have concluded the need for consensus on methods for studying the health risks of e-cigarettes. This includes determining which biomarkers are most relevant in relative and absolute studies. Larger sample studies are necessary for both e-cigarette users with a history of smoking and those who have never smoked in order to reach accurate conclusions.

When it comes to teenage addiction issues, researchers at the RCP have concluded that standardized plain packaging should be introduced, flavors and brand descriptions should be reduced, and retail display bans should be implemented to decrease teenagers' interest in trying e-cigarettes. Price and tax strategies for e-cigarettes should make the most commonly used and cheapest product by teenage e-cigarette users (disposable e-cigarettes) less affordable, while ensuring that products most likely to be used by adults who smoke or are trying to quit (rechargeable and refillable e-cigarettes) have minimal environmental impact and remain affordable.

The report also suggests increasing prices by imposing a consumption tax and setting minimum prices, prohibiting multiple purchases, but ensuring that they remain a more affordable option for adults who use them to quit smoking. It also recommends limiting the visibility of promotional materials in retail stores and products, as well as restricting promotional activities on social media. At the same time, the report authors are urging regulatory agencies to prevent cigarette manufacturers from influencing national policy-making.
