On June 20, the UK’s Daily Mail reported a significant surge in the usage of high-concentration nicotine e-cigarettes in England, based on a study conducted by University College London (UCL). The study highlights a dramatic increase, particularly among young people, with more than half of the 18 to 24 age group now using the strongest e-liquids.
Findings of the UCL Study
Increase in High-Concentration Usage
Dramatic Rise:
As of January 2024, one-third of e-cigarette users in England are using e-liquids with nicotine concentrations as high as 20 mg/ml. This is a significant rise from the average of 3.8% observed between July 2016 and June 2021.
Age Group Analysis:
The increase is particularly notable among young people aged 18 to 24, with more than half using the strongest e-liquids. However, the rise is also significant among older populations, current smokers, and recent quitters.
Survey and Analysis
Sample Size:
The study surveyed 7,314 adult e-cigarette users in England. Additionally, it analyzed survey data from Wales and Scotland to assess more recent usage patterns from 2022 to 2024.
Categorization:
E-liquids with a nicotine content of 20 mg/ml or above were categorized as high-concentration, which is the legal limit in the UK.
Factors Contributing to the Surge
Introduction of Disposable E-Cigarettes
Popularity Among Youth:
Dr. Sarah Jackson, the lead author of the study, noted that the rise in high-concentration e-cigarettes coincided with the introduction of new disposable e-cigarettes, which often contain nicotine at the legal limit. These disposable e-cigarettes are particularly popular among young users.
Unawareness of Nicotine Concentration
Labeling Issues:
The study found that many e-cigarette users, especially those using disposable and pod devices, are unaware of the nicotine concentration in their e-liquids. This points to a need for better labeling to ensure consumer awareness.
Implications for Public Health and Policy
Potential Health Risks
Exposure to Nicotine:
The sharp increase in the use of high-concentration nicotine e-cigarettes raises concerns about nicotine addiction and potential health risks, particularly for young people.
Use of Harmful Substances:
Taxing e-cigarettes based on nicotine concentration, as proposed by the UK government, might inadvertently lead users to opt for cheaper, lower-concentration products, potentially increasing the amount of e-cigarette use and exposure to harmful substances.
Policy Recommendations
Balanced Approach:
Deborah Arnott, CEO of Action on Smoking and Health (ASH) and co-author of the study, emphasizes the need to reduce the attractiveness of e-cigarettes to minors and increase prices at points of sale. However, she also highlights the importance of maintaining the efficacy of high-concentration nicotine e-cigarettes as smoking cessation tools for adults.
Enhanced Labeling:
Researchers suggest better labeling practices to ensure consumers are aware of the nicotine concentrations in their e-liquids. This can help users make informed choices and mitigate the risk of inadvertent high nicotine exposure.
Future Directions
Legislative Adjustments
Proposed Taxation:
The UK government has proposed setting three tax levels for e-liquids based on nicotine content, with the highest level for those with 11 mg/ml or more nicotine.
Regulation of Disposable E-Cigarettes:
With plans to ban disposable e-cigarettes, experts warn that high-concentration versions may be replaced by reusable models. This transition requires careful regulatory oversight to prevent unintended consequences.
Research and Monitoring
Ongoing Studies:
Continued research is needed to monitor the long-term effects of high-concentration nicotine e-cigarette use and to assess the impact of regulatory measures on smoking behaviors and public health outcomes.
Stakeholder Engagement:
Engaging with stakeholders, including health professionals, policymakers, and the e-cigarette industry, is crucial to developing effective and balanced regulations that protect minors while supporting adult smoking cessation efforts.
