To vape or not to vape? That question is fueling a heated debate in Geneva, where over 1,400 delegates are discussing the World Health Organization’s tobacco control treaty and the global “tobacco epidemic.”
E-cigarettes, heated tobacco and nicotine pouches have prompted warnings about new health risks and concern that the tobacco industry is promoting products that addict young non-smokers. At the same time, some doctors and public health experts argue these products may be less harmful than traditional cigarettes — which kill up to half of long-term users — and could help current smokers quit. The outcome matters: smoking rates have fallen, but about 1.2 billion people still use tobacco worldwide, roughly 80% in low- and middle-income countries.
WHO recently published a forceful position paper rejecting e-cigarettes as a cessation tool and urging strict regulation. The agency says the industry is “misappropriating” harm reduction language to mass-market harmful products and warns of mounting evidence of harm without proof of net public health benefit. WHO Director-General Tedros Adhanom Ghebreyesus emphasized industry profit motives over health. Officials note high use among children — an estimated 15 million worldwide — and warn flavors, packaging and marketing risk creating a new generation addicted to nicotine.
Medical groups echo those concerns. The International Pediatric Association warned in Pediatrics that e-cigarette use is associated with cardiovascular, metabolic, respiratory, oral diseases and cancer, and that dual users face greater risks than cigarette smokers alone. Critics say e-cigarettes could reverse decades of progress in tobacco control.
Advocates of harm reduction counter that completely prohibiting or demonizing these products ignores addiction’s complexity. Dr. Derek Yach, who helped draft WHO’s tobacco treaty, says the historic “quit or die” message failed to recognize nicotine addiction and that alternatives like e-cigarettes — which deliver nicotine without burning tobacco — may reduce exposure to the cancer-causing agents produced by combustion. Yach, whose advocacy for these products led some former colleagues to shun him, led the Foundation for a Smoke-Free World (later renamed and restructured), a group once funded by the tobacco industry — a connection that deepened controversy.
The U.K.’s National Health Service has embraced e-cigarettes as a cessation aid, and independent academics such as Mike Cummings argue safer alternatives deserve consideration for current smokers. Cummings says many researchers advocating harm reduction have been marginalized and that restricting debate about alternatives is “anti-science” censorship. He notes that industry funding of some groups complicates the conversation but argues it shouldn’t automatically disqualify evidence.
Opponents see the dispute as familiar industry tactics to divide public health efforts. Critics point to past industry claims — filtered cigarettes, low-tar products — that later proved deceptive. Tim McAfee, former head of the CDC’s Office on Smoking and Health, calls promotions of supposedly safer cigarettes an “unutterable scam” and views e-cigarette marketing as a smokescreen.
Scientific uncertainty remains. Products vary widely in design, nicotine delivery and emissions. Concerns have included exposure to metals from heating elements and other toxicants; studies have reached differing conclusions. WHO cautions against generalizing across diverse products and says long-term risks will become clearer only with time.
The debate centers on whether potential benefits for existing smokers outweigh risks to non-smokers, especially youth, and whether industry’s involvement renders harm-reduction claims suspect. Some call for rigorous, independent research and open debate to guide policy; others say precautionary regulation is essential to prevent new waves of addiction and disease.
