The chief marketing officer of embattled Juul Labs is leaving the company as part of a broad restructuring plan that also includes the suspension of all broadcast, print and digital product advertising in the U.S. In addition to CMO Craig Brommers, Chief Financial Officer Tim Danaher is leaving Juul as the company cuts 10 percent to 15 percent of its workforce to adjust to limits on sales of its flavored e-cigarette products, according to a person familiar with the matter.
