FDA Authorizes Juul2 E-Cigarette System, Citing Smoker Switching Data

Juul Labs has received marketing authorization from the U.S. Food and Drug Administration (FDA) for its new Juul2 e-cigarette system, including the device and its tobacco- and menthol-flavored pods. The agency's decision, announced Friday, hinges on data demonstrating the products' effectiveness in helping adult smokers transition away from combustible cigarettes.

Basis for Authorization

The FDA's scientific review concluded that authorizing the Juul2 system is appropriate for the protection of public health. The agency highlighted data from Juul's 2023 application showing that a substantial portion of adult smokers completely switched to the new device.

Key findings from the company's studies at six weeks include:

• Tobacco-flavored pod: Between 19.9% and 34.6% of users stopped smoking cigarettes entirely.
• Menthol-flavored pod: Between 28.4% and 49.3% of users stopped smoking cigarettes entirely.

Regulators determined that this benefit to adult smokers was sufficient to outweigh the potential risks associated with the products, including the appeal of menthol flavors to youth.

The Juul2 system is designed to offer a more consistent nicotine delivery experience to better compete with traditional cigarettes. The authorized pods contain a nicotine concentration of 18 mg/mL.

The new device incorporates several technological updates, including advanced thermal regulation, a Pod ID chip to prevent the use of counterfeit pods, and a connected smartphone app for users aged 21 and older. The app provides features such as device tracking and usage insights.

Market Context

This marks a significant regulatory milestone for the privately held vapor company, which received its first FDA authorization for the original Juul System in July 2025. According to the company, Juul Labs is the only major U.S.-based vapor firm not owned by or invested in by a traditional cigarette manufacturer.

Juul Labs assembles and fills its Juul2 pods at facilities in Tennessee and Wisconsin, using e-liquids produced in Maryland.
