The Wall Street Journal reported the FDA could reveal its decision as soon as Wednesday. The rejection would come following a review lasting two years of data presented by the company.
The vaping company has sought authorization for their tobacco- and menthol-flavoured e-cigarettes to remain on the US market.
The FDA first looked into Juul four years ago when its flavours and marketing strategy were blamed for a spike in vaping among underage individuals.
The company has since been trying to get back the trust of the authorities as well as the public. Juul restricted its marketing efforts and ceased the sale of sweet and fruit-flavoured e-cigarettes in 2019.
