One major health shift affecting over one hundred million vapers globally

A new study published in the journal Addiction has found that nicotine e-cigarettes are more effective for smoking cessation than traditional methods such as patches or gum.

Researchers at Oxford University conducted a meta-analysis to provide clear and consistent data supporting these devices as successful aids.

A 2024 review noted that an additional 2 to 5 people out of every 100 successfully quit smoking when using e-cigarettes compared to other therapies.

Angela Difeng Wu, senior researcher at Oxford, said: "We hope this overview and Evidence and Gap Map can lay to rest some claims that evidence is mixed regarding the impacts of nicotine e-cigarettes on smoking abstinence."

Despite the reduction in toxins, a February 2026 study confirmed the following:

• Vapers are still exposed to various carcinogenic chemicals.
• Long-term health impacts remain evolving and inconclusive due to the relative novelty of the products.
• Current data regarding serious health complications is insufficient to draw firm conclusions.

Global concerns and impact on children

The World Health Organization remains a vocal critic, arguing that these products are hooking children on nicotine and undermining tobacco control progress. Estimates for 2025 show:

• Over 100 million vapers exist globally.
• 15 million children aged 13-15 are included in these figures.

Ongoing controversies and perceived uncertainties continue to hamper international health policies and individual clinical decisions.

While switching from combustible tobacco reduces exposure to cancer-causing chemicals, the lack of long-term data persists as a significant concern for health officials worldwide.
