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.

FDA Revises Import Alert 98-07 Rules, Bringing May Enforcement Priorities Into Unauthorized ENDS Detentions
FDA Revises Import Alert 98-07 Rules, Bringing May Enforcement Priorities Into Unauthorized ENDS Detentions
The U.S. Food and Drug Administration has revised the rules under Import Alert 98-07 to incorporate its May 2026 enforcement-priority policy for certain electronic nicotine delivery systems marketed without premarket authorization. The alert continues to allow detention without physical examination, or DWPE, for ENDS lacking required marketing authorization, while directing field divisions to apply the May risk-based framework. When necessary, detention or refusal decisions must also undergo review by the FDA's Center for Tobacco Products. Products including PACHA and Vuse Pro have already emerged as industry examples of the May policy, although enforcement discretion does not constitute FDA marketing authorization.

Arizona Turns to a 50% Retail Vape Tax as Tobacco Tax Revenue Falls 47% From 2008
Arizona Turns to a 50% Retail Vape Tax as Tobacco Tax Revenue Falls 47% From 2008
Arizona's First Things First is pushing for an excise tax equal to 50% of the retail price of vaping products, estimating that the measure could generate about $100 million annually. The agency says its tobacco-tax revenue has fallen 47% from 2008 levels. Arizona has attempted to broaden its nicotine tax base in each of the past two years: a 2025 bill proposed a 50% wholesale-price tax, while a 2026 measure shifted to a 50% retail-price tax covering alternative nicotine products and vapor products. Separately, the state enacted HB 4001 this year to establish a new licensing and sales framework for alternative nicotine products.

Canada Health Minister Says She Is Not Considering Looser Nicotine Pouch Retail Rules as PMI-Linked Group Pushes for Wider Access
Canada Health Minister Says She Is Not Considering Looser Nicotine Pouch Retail Rules as PMI-Linked Group Pushes for Wider Access
Canadian Health Minister Marjorie Michel says she is not considering loosening retail restrictions on nicotine pouches. Canada regulates pouches containing 4 mg or less of nicotine per unit as non-prescription nicotine replacement therapy and requires newer NRT formats such as pouches to be sold from behind pharmacy counters. Meanwhile, Unsmoke Canada, linked to Philip Morris International's Canadian business, is pushing to allow pouches in convenience stores and other general retail outlets. Health Canada also acknowledges continued unauthorized sales, while recent research shows rising pouch use among Canadian youth aged 16 to 19.

Wisconsin Vape Directory One Year On: Retailer Reports Four Store Closures and 70% Staff Cuts
Wisconsin Vape Directory One Year On: Retailer Reports Four Store Closures and 70% Staff Cuts
Wisconsin's electronic vaping device directory has been fully enforced for more than a year, and local vape retailers say the reduced range of eligible products has contributed to declining sales, store closures and layoffs. Johnny Vapes owner Ben Hall said he has closed four of seven locations and cut about 70% of his staff. State law bars the sale of vaping devices not listed on the Wisconsin Department of Revenue directory and allows penalties of $1,000 per day for each unlisted device sold or offered for sale. In April 2026, the U.S. Court of Appeals for the Seventh Circuit allowed enforcement of the law to continue.

At the 2026 New Approaches Summit in New York, FDA Center for Tobacco Products Director Bret Koplow said the PMTA pathway is “predicated on tobacco harm reduction.” He outlined four CTP priorities: youth prevention, helping adults quit or switch to lower-risk products, improving relative-risk communication, and reducing unauthorized products. Koplow also addressed flavored e-cigarettes, public risk perceptions, industry credibility and efforts to make PMTA reviews more efficient and predictable.
