Nicotine Can Improve Intelligence in Elderly Dementia Patients
Nicotine can improve cognitive abilities in elderly patients with dementia, according to scientific research.

Scientific research has shown that nicotine can improve the intelligence of patients with Alzheimer's disease.


The study was conducted by a group of American scientists led by Paul Newhouse from the Vanderbilt University School of Medicine. The core team comprised of 45 males and 29 females aged 76, whose ability to absorb and perceive new information has slightly declined. The volunteers were observed continuously for six months.


Half of the patients received nicotine patches containing 15 milligrams of nicotine daily, while the rest were given a placebo (with no nicotine). Research shows that those who received nicotine saw an improvement in their symptoms during tests for memory, mental clarity, attention, and reaction time. On the other hand, those who received the placebo saw their condition worsen.

Scientists have observed a significant reduction in the amount of nicotine receptors in the brains of individuals with Alzheimer's disease, which negatively impacts their cognitive abilities.

South Korea Constitutional Court Upholds Volume-Based E-Liquid Tax, With Challenged Rates at KRW 370 and KRW 628 per Milliliter
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.

How Large Is France’s Off-Channel Tobacco Market? Logista Says It Has Become Structural, While the Official Estimate Is 17.7% and Some Industry Studies Put It Above 50%
How Large Is France’s Off-Channel Tobacco Market? Logista Says It Has Become Structural, While the Official Estimate Is 17.7% and Some Industry Studies Put It Above 50%
Logista France says tobacco consumption outside France’s official tobacconist network has become a large and structural market phenomenon, but official and industry estimates differ sharply. France’s TAFE study estimates that 17.7% of tobacco consumption escaped domestic taxation in 2023, with most of that volume attributed to cross-border purchasing rather than street sales. Some industry studies use broader off-channel definitions and put the figure above 50%. Meanwhile, French Customs seized 547.94 tonnes of tobacco in 2025, up 12%, showing continued pressure from illicit trade.

U.S. Rep. Krishnamoorthi Questions FDA Over Planned PMTA Rewrite, Seeks Communications With Altria and Reynolds
U.S. Rep. Raja Krishnamoorthi on Oct. 6 questioned the FDA over its plan to reassess and potentially replace the 2021 PMTA regulatory framework, asking the agency to identify provisions it may change or eliminate, state whether current scientific evidentiary standards will be maintained, and disclose communications with Altria, Reynolds and other parties challenging the rule. Krishnamoorthi led a congressional investigation into JUUL and youth vaping in 2019 and has since remained active on e-cigarette regulation and enforcement.

Cochrane 2026 Update Adds Nine Trials, Keeps High-Certainty Finding That Nicotine E-Cigarettes Improve Quit Rates Over NRT
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.

Germany's Bundestag passed amendments to the Tobacco Tax Act on October 15, 2026, setting out annual excise tax increases from 2027 through 2030 for e-cigarette liquids, heated tobacco, cigarettes and other tobacco products. Under the Finance Committee's amended bill, duty on qualifying e-liquids will rise from €0.32/ml in 2026 to €0.44/ml in 2030, an increase of 37.5%. Heated tobacco will retain its tax calculation based on 80% of the corresponding cigarette excise duty. The average price of a 20-cigarette pack is projected to approach €12 by 2030, with some brands potentially reaching €14. The legislation is projected to generate approximately €11.8 billion in additional tax revenue over four years and remains subject to further legislative procedures.
