Flum vape

FLUM is the leading single-use e-cigarette brand in the California market of the United States. However, all of its products have not been authorized by the US FDA, and their sales in California are illegal. As a result, the importer and the founder of FLUM are currently facing legal proceedings.

⚖️ Regulatory and legal disputes

Legal proceedings: In January 2025, the California Attorney General filed a lawsuit against FLUM's manufacturer, Flumgio Technology Inc., the importer, and its founder, Zaoyu Zhu (Zhu Early).
Law enforcement action: The FDA has sent warning letters to retailers selling FLUM products, and local authorities in California have also been conducting investigations.
