E-cigarette leader Juul shipped around one million mint-flavoured pods that were "contaminated," and then failed to inform customers or issue a recall once it realized the problem, according to a lawsuit filed by a former executive.
It comes as the vaping industry is facing tough scrutiny amid a mysterious epidemic of lung conditions linked to e-cigarette use that has killed 34 people and sickened around 1,500 in recent months.
In the lawsuit filed in a federal court in California on Tuesday, ex-senior vice president for finance Siddharth Breja's legal team wrote he was sacked for "whistleblowing" by objecting to the contaminated pods shipment and other unsafe conduct like selling expired or near-expired products.
The claims were termed "baseless" by the company, which told AFP that Breja was terminated "because he failed to demonstrate the leadership qualities needed in his role."
