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.

Couche-Tard Posts Double-Digit U.S. Same-Store Growth in Other Nicotine Products, Led by Pouches
Alimentation Couche-Tard said U.S. same-store sales in its “other nicotine products” category grew at a double-digit rate in the first quarter of fiscal 2027, led by nicotine pouches, while overall U.S. same-store merchandise revenues increased 1.7%. The company also said its Canadian nicotine business continued to face regulatory pressure and illicit-market headwinds. The U.S. performance coincides with Couche-Tard's participation in efforts to reopen Canadian convenience-store access to authorized nicotine pouches, though the company has not established a direct causal link between the two.
