Juul will let go up to 500 people by the end of 2019, somewhere between 10% and 15% of its workforce.
A company spokesperson confirmed the numbers in a Tuesday Wall Street Journal report.
Its chief marketing officer Craig Brommers is also leaving. The company said Tuesday that he asked to leave to "pursue other opportunities," and that it is eliminating the CMO position altogether.
The company told FOX Business that it had been hiring 300 people a month this year -- until September.
"As the vapor category undergoes a necessary reset, this reorganization will help JUUL Labs focus on reducing underage use, investing in scientific research, and creating new technologies while earning a license to operate in the U.S. and around the world," new Juul CEO K.C. Crosthwaite said in the statement.
When Crosthwaite took over, the company announced several new initiatives meant to calm the increasing legal, governmental, public and media maelstrom over vaping-related deaths, including stopping all U.S. advertising.
Juul is currently the target of various state and federal investigations for allegedly marketing its products to underage consumers.
"To right-size the business, the workforce will be reduced between now and the end of the year," the company said. "The reduction will be across various departments while some will continue to grow including teams working on PMTA and product."
