Potential Risks of Long-Term E-Cigarette Use

Potential Risks of Long-Term E-Cigarette Use
Studies on the potential dangers of long-term e-cigarette use vary, with some suggesting a 5% risk of potential harm.

Some studies have not quantified the potential risks of long-term use of electronic cigarettes. Others believe that while the dangers of e-cigarettes are 95% lower than traditional cigarettes, the remaining 5% represents a conservative estimate of potential risks from flavorings and ingredients over the long term. Some still insist that it is not possible to draw definitive conclusions today. According to one study, most tested models showed low levels of toxicity, and therefore do not pose a danger to users.


However, the author explains that this is not a reliable measure as the number of models and amounts of e-liquid in the market continue to increase without testing [4]. Ultimately, for the World Health Organization, the toxicity of e-cigarettes may be lower than tobacco, but according to them, there is no evidence to suggest the effectiveness of e-cigarettes in quitting smoking [5]. The view that conflicts with the Cochrane organization's point of view is that e-cigarettes are almost twice as effective as other nicotine replacement products (patches, gum, etc.) in quitting smoking.


In the end, the results from these different studies may vary and have different interpretations, but almost all the research agrees on one point: the current results are encouraging.

EU Vape, Heated Tobacco and Nicotine Pouch Tax Reform Reaches Ministerial Talks: Sweden Opposes Proposed 2032 Minimum of 50% of Retail Price or €50/kg for Nicotine Pouches
EU Vape, Heated Tobacco and Nicotine Pouch Tax Reform Reaches Ministerial Talks: Sweden Opposes Proposed 2032 Minimum of 50% of Retail Price or €50/kg for Nicotine Pouches
EU finance ministers are scheduled to discuss tobacco excise reform on November 9, 2026, seeking agreement on higher minimum duties for conventional tobacco and a common EU minimum tax framework covering e-cigarettes, heated tobacco and nicotine pouches. A November 5 Council document identifies nicotine pouch taxation as the main outstanding issue. The Irish Council presidency proposes phased increases, reaching 50% of retail selling price or €50 per kilogram in 2032. Sweden has formally said it cannot support the current compromise, objecting to both the proposed nicotine pouch tax burden and the adjustment of minimum rates based on national purchasing power. The package also addresses cross-border personal-use reference quantities, raw tobacco controls and the continued exclusion of traditional tobacco snus.
