The FDA's decision was based on Juul's studies, which demonstrated that its e-cigarettes are less harmful for adult smokers who switch from traditional cigarettes.
This ruling provides a new lease of life for Juul, which has faced years of intense regulatory scrutiny, numerous lawsuits, and significant financial difficulties due to concerns over teen vaping.
Juul will be one of only two companies permitted to sell menthol-flavored vapes in the US following this decision.
The ruling has drawn criticism from parents and anti-tobacco groups, who argue that Juul was responsible for the surge in youth vaping.
