E-cigarette use linked to vision impairment: study
A study found a 34% higher possibility of vision problems for e-cigarette users due to solvents causing oxidative stress.

A study titled "Association Between Electronic Cigarette Use and Visual Impairment in the United States" analyzed data from 1,173,646 adults aged 18 to 50 years old between 2016 and 2018. The results showed that electronic cigarette users were 34% more likely to develop visual impairment compared to non-users, and that their likelihood of developing visual impairment was 14% higher.


The team has demonstrated that solvents in e-cigarette liquids damage tear ducts and cause "oxidative stress" in the body, which is related to impaired vision.


A recent study published in the journal "Nicotine and Tobacco Research" by University of California, Los Angeles emphasized the relative safety of smokeless tobacco products and how transitioning from combustible cigarettes to these products could reduce the risk of cardiovascular disease among smokers.


The link between smokeless tobacco products and heart health


The study was conducted by a team of researchers from the University of California, Los Angeles, the University of California, San Francisco, Boston University, and the University of Texas at Arlington.


As part of the Population Assessment of Tobacco and Health (PATH) study, researchers analyzed data from a nationally representative sample of 4,347 adults who provided urine and blood samples during 2013-14. Of these participants, 3,034 reported using cigarettes only, 338 reported using smokeless tobacco only, and 975 reported never using any tobacco products.


According to compiled data, biomarkers for disease in non-smokers of tobacco products are significantly lower despite similar nicotine levels. "Our findings suggest that, despite higher nicotine content, the concentration of inflammatory and oxidative stress biomarkers is significantly lower in non-smokers of tobacco products compared to smokers," said Mary Rezk-Hanna, assistant professor at the UCLA School of Nursing. She added that the levels of these biomarkers in non-smokers of tobacco products are similar to those of individuals who have never smoked.

Reuters Tracks Big Tobacco’s Shift Beyond Cigarettes as Nicotine Pouches Vie for the Next Growth Curve
As cigarette markets face long-term pressure, major tobacco companies are increasingly turning to nicotine pouches in search of growth beyond combustible tobacco. Reuters has examined whether nicotine pouches can become the next strategic growth platform for companies including Philip Morris International, British American Tobacco and Japan Tobacco. PMI strengthened its position through the acquisition of Swedish Match and its ZYN brand, while BAT and JTI continue expanding their own nicotine pouch portfolios. The category has gained attention because of its smoke-free, device-free format, but regulation, youth-use concerns and market scale will determine whether it can become a long-term growth engine.

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.

STIIIZY Redesign Fails to Escape PAX Labs Patent Import Ban as Section 337 Case Also Involves China ALD
STIIIZY Redesign Fails to Escape PAX Labs Patent Import Ban as Section 337 Case Also Involves China ALD
U.S. Customs and Border Protection ruled that STIIIZY had not shown that the redesigned cannabis-vape products covered by its latest request fall outside an ITC limited exclusion order tied to PAX Labs patents. CBP accepted some of STIIIZY’s claim-construction and non-infringement arguments, but the company did not address two additional claims in the same patent. Earlier STIIIZY redesigned cartridges and certain associated components imported with them had received separate CBP clearance.
