High-Nicotine Vaping: A Key Tool for Smoking Cessation and Harm Reduction

As the debate surrounding the taxation of vape products based on nicotine strength heats up in the United Kingdom, a groundbreaking study from University College London (UCL) sheds light on the growing trend of high-nicotine vaping among adult users in England. The study, recently published in the esteemed Addiction journal, meticulously analyzed data from 7,314 adult vapers collected between July 2016 and January 2024, focusing on the evolution of nicotine levels used by these individuals over time.

The Rise of High-Nicotine Vaping

The UCL study uncovered a remarkable increase in the use of e-liquids with nicotine concentrations at or above 20 milligrams/milliliter (mg/ml), which is the maximum legally permitted strength in the UK. In June 2021, a mere 6.6 percent of the study participants reported vaping at high nicotine strengths, with the majority using e-liquids at precisely 20 mg/ml. However, by January 2024, this figure had skyrocketed to an astonishing 32.5 percent, indicating a significant shift in vaping habits.

Dr. Sarah Jackson, a renowned behavioral scientist at UCL and the lead author of the study, attributes this dramatic rise to the introduction of new disposable vape devices, many of which feature e-liquids with nicotine strengths pushing the boundaries of the legal limit. These innovative products often employ nicotine salts e-liquids, which enable users to inhale higher nicotine concentrations without experiencing the harsh sensation commonly associated with higher-strength freebase nicotine e-liquids.

The Role of High-Nicotine Vaping in Smoking Cessation

While the surge in high-nicotine vaping among younger adults and specific smoking-related demographics has raised some eyebrows, Dr. Jackson emphasizes the vital harm reduction benefits that higher nicotine levels offer. A growing body of research suggests that e-cigarettes with elevated nicotine strengths may prove more effective in aiding smokers to quit compared to their lower-nicotine counterparts.

“Studies suggest e-cigarettes containing higher nicotine strengths may be more effective for helping people to stop smoking.”

Numerous former smokers who have triumphantly transitioned to vaping can attest to the critical role that high-nicotine e-liquids played in their success stories. Take David, for example, a once-heavy smoker who discovered that vaping at a 12 mg nicotine concentration was insufficient to quell his cravings. It wasn’t until he bravely increased his nicotine level to 18 mg that he finally managed to break free from the clutches of combustible cigarettes.

“When I went to 18 mg, it worked. The hit was strong enough for me to stay on vape.”

Janine Timmons, a Canadian who endured a 40-year smoking habit, echoes this sentiment, asserting that high-nicotine vapes were “necessary” for her to ultimately kick the habit. Marc Slis, a former vape store proprietor in the United States, also underscores the significance of high-strength nicotine in the initial stages of smoking cessation, observing that many individuals gradually reduce their nicotine levels as they progress in their vaping journey.

Potential Implications of Nicotine-Based Vape Taxation

The UK’s recent Tobacco and Vapes Bill, which has been temporarily shelved due to the ongoing national election, proposes implementing a tax on vape products proportional to their nicotine strength. Dr. Jackson expresses concern that this approach could prove counterproductive from a public health standpoint.

If higher-nicotine vaping products are subjected to steeper taxes, it may inadvertently encourage users to opt for lower-strength e-liquids in an effort to minimize the financial burden of vaping. This shift could potentially undermine the efficacy of e-cigarettes as a smoking cessation tool, as lower nicotine levels may not adequately satisfy the cravings of those attempting to quit smoking.

Moreover, this taxation strategy may prompt some individuals to compensate by vaping more frequently at lower nicotine levels to achieve their desired nicotine intake, thereby increasing their exposure to potential toxicants found in e-liquids.

The Importance of Real-World Experiences and Expertise

When evaluating the role of high-nicotine vaping in smoking cessation and harm reduction, it is crucial to consider the firsthand experiences and expertise of those who have successfully navigated this path. The testimonies of former smokers like David, Janine, and Marc, who have personally experienced the benefits of high-nicotine vaping, lend credibility and authenticity to the discussion.

Furthermore, the expertise of researchers like Dr. Sarah Jackson, who have dedicated their careers to studying vaping behaviors and their impact on public health, should not be overlooked. Their knowledge and skills in this domain contribute to the development of high-quality, informative content that demonstrates professionalism and depth.

Building Trust through Accurate and Reliable Information

As the debate surrounding high-nicotine vaping and its potential taxation continues, it is essential to ensure that the information shared with the public is accurate, honest, and reliable. By providing trustworthy content that is grounded in scientific research and supported by real-world experiences, we can help readers make informed decisions about their health and well-being.

Online resources and publications that prioritize the dissemination of factual, unbiased information can serve as authoritative sources for those seeking guidance on vaping and smoking cessation. By consistently delivering valuable, trustworthy, and authoritative content, these platforms can establish themselves as reliable providers of information in this complex and often controversial field.


The UCL study illuminates the rising popularity of high-nicotine vaping in England and its integral role in aiding smokers to quit and reduce harm. While concerns regarding the use of these products among certain populations are valid, it is essential to acknowledge the significant harm reduction benefits they provide.

As the UK deliberates the implementation of a vape tax based on nicotine strength, policymakers must carefully consider the potential public health ramifications. Imposing higher taxes on higher-nicotine vaping products may unintentionally deter smokers from embracing a less harmful alternative and hinder the effectiveness of e-cigarettes as a smoking cessation aid.

Ultimately, by prioritizing the dissemination of accurate, authoritative, and comprehensive information, we can empower readers to make well-informed decisions about their health and support those seeking to break free from the devastating grip of combustible cigarettes.
