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.

Charlie’s Bets on Age-Gating and 678 PMTA Assets as U.S. Vape Enforcement Landscape Shifts
Charlie’s Holdings said in its latest shareholder letter that it is moving to commercialize PACHA products and monetize its PMTA assets as the FDA changes enforcement priorities for unauthorized ENDS products. Thirty PACHA SKUs were previously tentatively identified for a proposed public list of products that the FDA generally does not intend to prioritize for enforcement. Charlie’s is also preparing test-market sales of age-gated flavored disposables and says it currently holds 678 PMTA-related product assets while seeking additional strategic transactions and partnerships.
