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.

New Nicotine Products Added to Tax List in Delaware Budget Proposal
Delaware Governor Matt Meyer’s proposed FY2027 budget would significantly raise cigarette and nicotine product taxes to help close a $500 million budget gap and generate new revenue. The cigarette tax would rise from $2.10 to $3.60 per pack, with increases on moist snuff, e-liquids and other tobacco products. Supporters say the move is justified, while small businesses warn of potential sales losses.

Oklahoma DOC to allow inmates to buy nicotine vapes and pouches in 2026
Oklahoma’s Department of Corrections says it will begin allowing inmates to buy single-use nicotine vapes and nicotine pouches through prison canteens in 2026, framing the move as a strategy to reduce contraband-driven debts and prison violence. Officials say inmates will be barred from using personal nicotine products, the devices will be disposable and non-cartridge-based, and the program will be self-funded through inmate purchases rather than taxpayer money.
