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.

Japanese Addiction Psychiatrist Says Complete Abstinence Is Not Always the Goal of Harm Reduction | 2Firsts Interview
Japanese Addiction Psychiatrist Says Complete Abstinence Is Not Always the Goal of Harm Reduction | 2Firsts Interview
Complete abstinence is not always the goal of addiction treatment under a harm-reduction approach, Japanese psychiatrist Tomohiro Shirasaka told 2Firsts in Manila. In the interview, he discussed patients' quality of life, Japan's shift towards heated tobacco products, and the challenges of quitting smoking for people with mental illness. Drawing on addiction treatment work in the Philippines, he advocated support rather than punishment and questioned whether fear-based health warnings effectively address the reasons people continue smoking.

UK ONS Data: Vaping Rate Among Women Aged 25–34 Reaches 18.3%, Compared With 14.4% for Men
The vaping rate among women aged 25 to 34 in Great Britain reached 18.3% in 2025, up from 13.7% in 2024 and 8.3% in 2020, according to data from the Office for National Statistics (ONS). The figure was the highest for this group since records began in 2014 and exceeded the 14.4% recorded among men of the same age. Adults aged 25 to 34 also overtook those aged 16 to 24 as the age group with the highest vaping prevalence. Overall, about 5.4 million adults in Great Britain used e-cigarettes in 2025, broadly unchanged from the previous year.

Malaysia's Poisons Board Backs New Vape Nicotine Exemption After Unanimously Opposing 2023 Proposal
Malaysia's Poisons Board Backs New Vape Nicotine Exemption After Unanimously Opposing 2023 Proposal
Malaysia's Poisons Board has endorsed Health Minister Dzulkefly Ahmad's proposal to exempt liquid nicotine used in vaping products from the Poisons List, according to a November 2, 2026, report by CodeBlue. The Board unanimously opposed a similar proposal in 2023, but the government proceeded with the exemption. The Kuala Lumpur High Court invalidated the 2023 decision in May 2026, and the government withdrew its appeal in August. No new ministerial order has been published. The development raises questions about the interaction between Malaysia's two regulatory frameworks and the treatment of RM354.51 million in excise duties collected on e-cigarette and vape products between May 2023 and June 11, 2026.

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.

Special Report | From New York to Washington: How FDA’s Tobacco Center Is Reworking Product Review
FDA’s Center for Tobacco Products is reshaping how it approaches tobacco product review. Based on 2Firsts’ on-site reporting in New York and Washington, this report traces CTP’s emerging direction: stronger links between PMTA and tobacco harm reduction, more category-specific review, greater emphasis on decision-relevant science, more predictable timelines and expanded use of sPMTA for product modifications. CTP also acknowledged major constraints, including just nine PMTA review teams, persistent backlogs and limits on hiring capacity.
