New Study by Yale University Raises Concerns About E-Cigarettes
Yale study reveals some e-cigarettes may contain potent nicotine-like chemicals, raising health concerns beyond FDA regulation.

According to a report by Newsweek on August 12, a previous study by Yale University found that some e-cigarettes may contain chemical compounds similar to nicotine that could have unknown effects on health.


These nicotine alternatives interact with receptors in the brain, without being subject to FDA restrictions and regulations. As a result, these products are able to be marketed with flavors that appeal to young people and avoid tobacco taxes.


An FDA spokesperson stated that these new chemicals may be more potent than nicotine and could potentially affect the brain development, learning abilities, and memory of adolescents.


FDA Public Affairs Specialist Jim McKinney told Newsweek that...


The FDA is addressing this issue from the perspective of the entire agency and will continue to utilize all resources within its authority to protect the public, especially American adolescents, from potentially harmful addictive products.


McKinney points out that, although more research is needed, some emerging data suggests that these nicotine analogs may be more potent than nicotine itself, which is already highly addictive, altering adolescent brain development and producing long-term effects.


According to research, nicotine analogs are chemical substances that are structurally very similar to nicotine and therefore target the same receptors in the brain. Examples include 6-methyl nicotine and nicotineamide. A study in rodents suggests that 6-methyl nicotine may be more toxic than nicotine. Furthermore, because these compounds are not subject to the same strict regulations as traditional nicotine, the ingredients listed on labels may not always match the actual ingredients in the products.


Dr. Hanno Erythropel, a scientist at the Yale School of Medicine, stated in a press release,


In conclusion, the company is actually trying to evade regulation by introducing new products containing nicotine analogues with unknown health and addiction risks.


In a study published in the journal "JAMA Network," the researcher and their colleagues analyzed two e-cigarette and e-liquid products on the market. The first product, Spree Bar, claimed to contain 5% of 6-methyl nicotine (50 milligrams/gram), while the second product, Nic-Safe, was tested at four concentrations—0, 12, 24, and 36 milligrams/milliliter.


The research results show that both products do not contain the ingredients as specified on their labels. Spree Bar actually contains 90% less 6-methyl nicotine than advertised, while Nic-Safe contains a low concentration of 6-methyl nicotine without it being clearly marked on the label (excluding tested nicotine-free products).


FDA spokesperson Mackinney said that


In general, the FDA does not comment on specific studies, but instead uses them as part of the evidence to further understand specific issues and help achieve its mission of protecting public health. Regarding nicotine mimetics, the FDA is aware that some companies are reported to be producing products that may contain compounds with chemical structures or properties different from nicotine.

Yinghe-Controlled Vape Maker SKE Ordered to Post £569,039 Security as It Pursues Crystal Bar Design Infringement Case in UK
Yinghe-Controlled Vape Maker SKE Ordered to Post £569,039 Security as It Pursues Crystal Bar Design Infringement Case in UK
The UK High Court has ordered Chinese vape manufacturer Shenzhen SKE Technology to provide £569,039 ($776,000) in security for costs in its design infringement proceedings against Vapepen London and other defendants over its Crystal Bar vape product. The court did not accept the defendants’ main argument that recovering costs from a China-based company would face significant enforcement obstacles, but found that SKE had not sufficiently disclosed its own financial position. The order is procedural and does not determine the underlying infringement claims.

Australia Brings in Deloitte to Support Illicit Tobacco and Vape Enforcement Across Data, Processes and Project Delivery
Australia’s Department of Home Affairs has hired Deloitte to provide data analytics, business-process, communications and project-delivery support to the Office of the Illicit Tobacco and E-Cigarette Commissioner. The government says Deloitte personnel do not provide policy advice to the Commissioner or the Australian government, with policy development and decision-making remaining with public officials. The arrangement has nevertheless drawn scrutiny because Deloitte has previously provided professional services to several tobacco and vaping companies.

NAS 2026 | Cliff Douglas: Risk Continuum Should Play a Central Role in Tobacco Policy
Cliff Douglas, a veteran U.S. tobacco-control and public health policy figure, told NAS 2026 that the “continuum of risk” should play a central role in tobacco policy. He called for clearer market pathways, stronger risk communication, differentiated regulation and enforcement, and said possible FDA reforms to PMTA reviews could be a “welcome correction” if they create a more efficient, predictable route for scientifically substantiated lower-risk products.

From Nicotine Salts to Cocrystals: China’s Shenzhen Huabao institute explores a more stable form for sustained nicotine release
From Nicotine Salts to Cocrystals: China’s Shenzhen Huabao institute explores a more stable form for sustained nicotine release
China-based Shenzhen Huabao Collaborative Innovation Technology Research Institute Co., Ltd. has filed a patent application for a nicotine-ascorbic acid cocrystal, exploring a new solid-state form of nicotine. The patent proposes applications across e-liquids, heated tobacco sticks, oral tobacco, chewing tobacco and snuff. In nicotine pouch tests disclosed in the filing, cocrystal formulations showed less than a 6% decline in nicotine content after three months of accelerated storage and a release profile combining early-stage release with sustained delivery over 60 minutes. The filing reflects exploration of nicotine forms beyond conventional nicotine base and nicotine salts.

From December 1, newly manufactured and imported covered devices will be required to carry digital identification codes and be reported as entering circulation. Russia has also issued new operational guidance for imports, marking the transition from a voluntary pilot to phased mandatory implementation.
