E-cigarettes and Health: A Comprehensive Review of Evidence on Vaping
E-cigarettes and Health. In recent years, the popularity of electronic cigarettes, or e-cigarettes, has surged, raising concerns about their impact on public health. A recent evidence review, led by academics at King’s College London and commissioned by the Office for Health Improvement and Disparities in the Department of Health and Social Care, sheds light on the health risks associated with nicotine vaping. This eighth in a series of independent reports on vaping, originally commissioned by Public Health England, aims to provide the most comprehensive analysis to date. Here, we explore the key findings of this report, focusing on health risks, prevalence among different age groups, flavors, nicotine levels, and harm perceptions.

Health Risks
The evidence review concludes that in the short and medium term, vaping poses a small fraction of the risks of smoking. However, it emphasizes that vaping is not entirely risk-free, especially for individuals who have never smoked. The evidence primarily relies on data regarding human exposure to vaping, supported by animal and cell studies. The report emphasizes the need for more extended studies assessing the long-term effects of vaping, exceeding 12 months, to provide a more comprehensive understanding of its health implications.

Biomarkers of Toxicant Exposure
The report delves into biomarkers of toxicant exposure, indicating significantly lower exposure to harmful substances from vaping compared to smoking. Biomarkers associated with the risk of cancer, respiratory, and cardiovascular conditions are notably reduced in vapers compared to smokers. However, similar or higher exposure to harmful substances from vaping is observed compared to individuals not using nicotine products. Importantly, the report finds no significant increase in toxicant biomarkers after short-term secondhand exposure to vaping among non-smokers or non-vapers.

Smoking and Vaping Prevalence
Among young people aged 11 to 18 in England, the prevalence of vaping has increased, surpassing smoking rates. Current vaping prevalence stands at 8.6%, while smoking prevalence is 6%. It’s noteworthy that most young people who have never smoked are also not currently vaping. However, the rise of disposable vaping products among current vapers has seen a substantial increase. Among adults, smoking prevalence in 2021 ranged from 12.7% to 14.9%, whereas vaping prevalence ranged from 6.9% to 7.1%, depending on the survey.
-
Flavors
Fruit flavors remain the most popular among both adults and young people who vape, followed by ‘menthol/mint.’ However, the report highlights a lack of evidence regarding the impact of flavorings on health risks. Concerns are raised specifically about vaping products containing the flavoring chemical cinnamaldehyde, calling for regulatory bodies to review its use in e-liquids.
-
Nicotine
While vaping products generally provide lower nicotine levels than smoking, experienced vapers can achieve nicotine levels similar to smokers. The risk and severity of nicotine dependency from vaping are found to be lower than from smoking, but variations exist based on product characteristics, such as device type and nicotine concentration in e-liquids.
-
Harm Perceptions
The evidence review underscores the importance of addressing inaccurate perceptions about vaping. In 2021, only 34% of adults who smoked accurately believed that vaping was less harmful than smoking. Correcting misperceptions is crucial, as people’s perceptions about vaping harms can influence their subsequent vaping and smoking behavior. Effective communication of accurate information regarding the relative harms of vaping can play a pivotal role in dispelling misconceptions, particularly among adults.
The comprehensive evidence review on vaping provides valuable insights into the health risks associated with e-cigarettes. While acknowledging the reduced risks compared to smoking, the report emphasizes the importance of continued research, standardized methodologies, and accurate communication to guide public health policies and interventions. As the landscape of vaping evolves, staying informed and addressing misconceptions will be crucial in promoting a balanced understanding of the health implications of e-cigarettes.
