E-cigarette use increases addiction risk, study finds.
E-cigarette use for smoking cessation increases addiction risk, according to studies by Ohio and Washington universities.

A new study in Cleveland, Ohio suggests that using electronic cigarettes to quit smoking may lead to addiction for users. Similarly, a recent study from the medical school at Washington University in St. Louis found that those who use e-cigarettes to quit smoking are at an increased risk for addiction to both. Researchers said that since e-cigarettes contain nicotine, they are just as addictive as traditional cigarettes.

This study examined electronic health record data from approximately 112,000 smokers seeking outpatient treatment at a hospital between 2018 and 2020. During the study period, the number of smokers who also started using e-cigarettes doubled, from 0.8% in the first year to over 2% in the second year. About one-fifth of "dual-use" smokers did successfully quit within a year, with slightly higher success rates than those who only smoked cigarettes. However, the study found that about two-thirds of smokers who used both cigarettes and e-cigarettes were still smoking after one year. Dual-use smokers who used traditional smoking cessation methods were more likely to quit.

Australian Coalition Unveils Illicit Tobacco Plan With 80% Excise Cut and Legal, Taxed Vapes and Nicotine Pouches
Australian Coalition Unveils Illicit Tobacco Plan With 80% Excise Cut and Legal, Taxed Vapes and Nicotine Pouches
Australia’s Coalition has unveiled a national illicit-tobacco policy that would cut tobacco excise by 80% and create legal, regulated and taxed adult markets for vaping products and nicotine pouches if it wins government. The plan proposes an excise of A$0.50 per millilitre of e-liquid and A$0.025 per milligram of nicotine in pouches, alongside A$200 million in additional enforcement and a A$60 million three-year public-awareness campaign. The Coalition says the package would narrow the price advantage of illicit products and undermine organised crime, while Labor and public-health groups warn that dramatically cheaper cigarettes could reverse long-term declines in smoking.

Juul Sublicense Reshapes Vuse Alto Patent Bill as Court Ends R.J. Reynolds’ 5.25% Royalty Obligation to Altria
Juul Sublicense Reshapes Vuse Alto Patent Bill as Court Ends R.J. Reynolds’ 5.25% Royalty Obligation to Altria
According to Law360 on August 31, 2026, a federal judge in North Carolina ruled that a patent sublicense between R.J. Reynolds Vapor Co. and Juul Labs Inc. relieves Reynolds of its obligation to continue paying royalties to Altria Client Services LLC over Vuse Alto. A jury had previously found that Vuse Alto infringed three Altria patents and awarded approximately $95.2 million in past damages, after which Reynolds was ordered to pay an ongoing royalty equal to 5.25% of positive net sales. The new ruling finds that a valid sublicense can eliminate future infringement, potentially ending what Altria described as hundreds of millions of dollars in future royalties.

Australia Adds 6-Methylnicotine to Schedule 9 Prohibited Substances, Effective October 1
Australia Adds 6-Methylnicotine to Schedule 9 Prohibited Substances, Effective October 1
Australia's Therapeutic Goods Administration published a final decision on September 25 to classify 6-methylnicotine as a Schedule 9 prohibited substance under the Poisons Standard, effective October 1, 2026. TGA said the chemical has been reported in e-cigarette liquids sold in Australia and marketed as nicotine-free or nicotine alternatives, while evidence also indicates its use in preparations such as oral pouches. The government originally proposed a Schedule 7 classification but ultimately adopted the stricter Schedule 9 designation, citing acute toxicity, dependence risk, use in unapproved consumer products and misleading marketing.
