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.

JAMA Study: U.S. Vape Directories Fail to Sustainably Curb Unlisted Sales as Product Shifts May Redistribute Brand Share 2Firsts Recommended
JAMA Study: U.S. Vape Directories Fail to Sustainably Curb Unlisted Sales as Product Shifts May Redistribute Brand Share 2Firsts Recommended
A study by CDC Foundation researchers found no sustained decline in e-cigarette sales across Alabama, Oklahoma and Louisiana, the first three U.S. states to implement e-cigarette directory laws. Louisiana initially saw a significant sales decline, followed by a rebound and a persistent reduction in product availability. Sales also shifted from nontobacco-flavored disposables toward prefilled cartridges, with Vuse Alto driving much of the increase in menthol cartridges. By April 2025, unlisted products still accounted for more than half of e-cigarette nicotine sales in all three states.

Product | KIWI Launches Spark 2 and Spark 2 Pro in Germany, Two Hardware Tiers Share Backward-Compatible 2ml Pods
KIWI has launched the Spark 2 and Spark 2 Pro refillable pod systems in Germany at official prices of €18 and €29, respectively. Spark 2 uses an 800mAh removable lithium-ion battery in a pen-style body, while Spark 2 Pro features a 1,400mAh removable battery, a box-shaped design and vibration feedback every 20 puffs. Both devices use the same 2ml Spark V2 pods in 0.8Ω and 1.2Ω versions, with AirSync airflow adjustment and a choice between Cotton Tips and conventional Drip Tips. The new pods also remain compatible with the original KIWI Spark.

Australia Extends Illicit Tobacco Crackdown From Tougher Penalties to Customs and Logistics Supply Chains
Australia Extends Illicit Tobacco Crackdown From Tougher Penalties to Customs and Logistics Supply Chains
Australia's federal government introduced a new illicit tobacco enforcement bill on September 10 that would strengthen evidentiary presumptions, representative sampling, seizure and forfeiture procedures, proceeds-of-crime powers and obligations for customs and logistics operators. The proposal follows the Combatting Illicit Tobacco Act 2026, which took effect in August and increased penalties while expanding investigative and asset-recovery tools. Together, the reforms extend Australia's crackdown from tougher criminal sanctions into import, logistics and evidentiary enforcement.

JAMA Issues First U.S. Clinical Guidance on Vaping for Smoking Cessation, Urging Complete Switch From Cigarettes
JAMA Issues First U.S. Clinical Guidance on Vaping for Smoking Cessation, Urging Complete Switch From Cigarettes
JAMA has published a Special Communication offering systematic recommendations for U.S.-based clinicians on the use of nicotine e-cigarettes in adult smoking cessation. Developed by the Harm Reduction Workgroup of the Society for Research on Nicotine and Tobacco’s Treatment Research Network, the paper recommends including e-cigarettes alongside FDA-approved cessation medications in risk-benefit discussions. It cites high-certainty evidence that nicotine e-cigarettes achieve higher quit rates than nicotine replacement therapy and evidence suggesting efficacy comparable to highly effective medications such as varenicline and cytisine. For adults who choose vaping to quit, the authors recommend FDA-authorized products, sufficient nicotine delivery and a rapid, complete transition away from cigarettes rather than prolonged dual use.

Australia Tobacco Tax Debate Spreads Within Labor as NSW Premier Minns Reaffirms Support for a Cut
Australia’s tobacco excise debate is increasingly exposing differences within the governing Labor Party. New South Wales Labor Premier Chris Minns reaffirmed on September 8 that he supports reducing tobacco excise, arguing that current tax settings are pushing consumers toward cheaper black-market cigarettes. Federal Health Minister Mark Butler continues to oppose an excise cut, while Treasurer Jim Chalmers and Assistant Treasurer Daniel Mulino have recently stopped short of ruling out future changes. The divergence follows the opposition Coalition’s proposal to cut tobacco excise by 80%.

Cochrane 2026 Update Adds Nine Trials, Keeps High-Certainty Finding That Nicotine E-Cigarettes Improve Quit Rates Over NRT
Cochrane’s 2026 update of its living review on electronic cigarettes for smoking cessation included 80 randomized controlled trials involving 29,861 adult smokers, with nine trials added in this update. The review retained its high-certainty conclusion that nicotine e-cigarettes increase smoking cessation rates compared with nicotine replacement therapy. In absolute terms, about 10 in 100 people using nicotine e-cigarettes may quit smoking for at least six months, compared with about 6 in 100 using NRT. The review found no clear difference in serious adverse event rates between the two groups, while longer-term safety and the relative effectiveness of newer device types remain less certain.
