Why did the FDA ban Juul products?
The Juul ban follows a two-year review of the company’s applications to continue selling its e-cigarette device and menthol and tobacco pre-filled cartridges.
he agency denied the applications, saying they “lacked sufficient evidence regarding the toxicological profile of the products to demonstrate that marketing of the products would be appropriate for the protection of the public health.”
The FDA said it hasn’t received information to suggest an immediate hazard associated with the use of Juul products, but “there is insufficient evidence to assess the potential toxicological risks of using the JUUL products.”
“As with all manufacturers, JUUL had the opportunity to provide evidence demonstrating that the marketing of their products meets these standards,” Michele Mital, acting director of the FDA’s Center for Tobacco Products, said in a statement. “However, the company did not provide that evidence and instead left us with significant questions.”
Conclusion
Juul vaping products have been viewed as particularly problematic for teens and young adults. The company’s wide variety of sweet flavors such as mango and other fruits appealed to a wider customer base. Many young people were more interested in sweet vaping products than those that taste like cigarettes, and Juul devices look much like a USB flash drive, making it easier for students to use vaping products in classrooms and other school areas.
