Cochrane Lab Reports on Harm Reduction in Heated Tobacco Products
New Cochrane lab research suggests that switching from traditional cigarettes to HTPs may lower the risk of certain illnesses.

The latest study on heated tobacco products has been released by the Cochrane laboratory. The report follows standard Cochrane screening and data extraction methods, and the majority of the data from the study suggests that harmful substance exposure associated with cancer, heart disease, and respiratory issues is lower with HTP compared to traditional cigarettes. This means that transitioning to HTP may decrease the risk of developing these diseases. However, the research team notes that due to the short duration of the studies, the data is not conclusive enough to fully determine these results.


Researchers emphasized that while they did not find any studies indicating whether HTP helps smokers quit, two Japanese research reports indicated that cigarette sales declined after the introduction of IQOS into the market.


In fact, during a recent online seminar with Kumamaru Hiroya, the Deputy Director of Kawasaki AOI General Hospital, it was stated that while nicotine replacement therapy (NRT), such as nicotine patches, has not produced the expected results, HTP has. Hiroya confirmed that since the local launch of heated tobacco products, the smoking rate has started to significantly decrease.


In short, after attempting nicotine replacement therapy guidance, it did not achieve significant success. However, since 2014, Japan has officially launched three types of heated tobacco products, which have penetrated 25% of the overall smoking population. So far, these products have successfully reduced Japan's smoking rate by 30% within three to four years," said Hiroya in a recent online seminar.


HTP's Aerosol Particles


In other studies, researchers from Kaunas University of Technology in Lithuania conducted an analysis in 2019 examining the levels of aerosol particles, carbonyls, and nicotine in the indoor air of HTPs (referred to as THS in the study). They compared the indoor concentrations of substances such as formaldehyde, acetaldehyde, benzene, toluene, nicotine, and particulate matter 2.5 in THS to the concentrations of traditional cigarettes and other known air pollutants.


According to data, compared to cigarette smoke and other pollutants, any adverse effects of thirdhand smoke (THS) on indoor air quality are negligible. "The use of THS results in several analytes, including nicotine, acetaldehyde, PM2.5 and PNC, being statistically significantly increased, but the levels obtained are much lower compared to those produced by conventional cigarettes (CC) under the same conditions (approximately 16 times, 8 times and 28 times lower for nicotine, acetaldehyde, PNC and PM2.5, respectively).


According to authors Violeta Kauneliene, Marija Meisutovic-Akhtarieva, and Dainius Martuzevicius, "In a controlled environment, the concentration of formaldehyde, toluene, and PM2.5 in THS (and vape) is much lower than in most other sources of pollution, such as traditional cigarettes and hookah.

Special Report | How Capital Is Reassessing the Global Tobacco and Modern Nicotine Industry: Lessons from a New York Forum
Capital is reassessing the global tobacco and modern nicotine industry as heated tobacco, vaping and nicotine pouches reshape demand, profitability and regulation. At the 2026 New Approaches Summit in New York, investors and analysts examined whether smoke-free growth can sustain earnings, how regulation shapes startup value, and whether shareholder engagement can be more effective than divestment. The debate points to a broader shift: tobacco transition is increasingly becoming a capital-allocation, governance and valuation question.

New Zealand Associate Health Minister Casey Costello Warns on Illicit Cigarettes as Legal Tobacco Sales Halve Over Decade
New Zealand Associate Health Minister Casey Costello said legal tobacco sales in the country have fallen by more than half over the past decade, with sales declining more than 20% in 2025 compared with the previous year. She warned that the decline may not fully reflect lower smoking rates, as increased availability of illicit cigarettes could also be contributing. The government said it would continue strengthening tobacco and vape retail enforcement while monitoring the impact of illicit tobacco on public health and tax revenue.

South Korea Constitutional Court Upholds Volume-Based E-Liquid Tax, With Challenged Rates at KRW 370 and KRW 628 per Milliliter
South Korea's Constitutional Court has upheld fixed taxes on nicotine-containing e-cigarette liquids based on solution volume, ruling that challenged provisions imposing KRW 370 per milliliter in individual consumption tax and KRW 628 per milliliter in tobacco consumption tax do not violate the Constitution. The cases stemmed from historical disputes involving importers that reported nicotine as being extracted from tobacco stems rather than leaves. South Korea has since broadened its tobacco definition to include synthetic nicotine, while current tax laws provide reduced rates for certain products not derived from tobacco.
