According to Law360, cannabis vape company Stiiizy Inc. is facing another California state-court lawsuit alleging it markets high-THC vape products to teens, contributing to what the complaint calls a nationwide “cannabis-induced psychosis” (CIP) “epidemic.”

The plaintiff, suing anonymously as John Doe RC, says he was a 17-year-old high school senior in 2024 when he began using Stiiizy products, drawn by the company’s marketing and the products’ standing among his peers. He alleges he later suffered CIP-related effects, including mood swings, depression, aggressive behavior and a suicide attempt.

The complaint alleges Stiiizy uses flashy colors, flavor-style names such as “Purple Punch,” “Dreamsicle,” and “Gelato,” and advertising featuring young, attractive women to appeal to teenagers. It also claims the company’s website uses a weak age-gate system that requires only a “Yes” click when users are asked whether they are over 21.

The lawsuit further highlights potency, alleging Stiiizy vape pods reach THC concentrations as high as 92%, and argues that high-potency THC products are linked to CIP risk while the company fails to adequately warn consumers. The complaint also references figures asserting CIP-related emergency room visits rose to 1,053 in 2019 from 682 in 2016, and contends teens face heightened risk due to ongoing brain development.

Law360 reports this is the ninth similar lawsuit filed against Stiiizy by the same group of attorneys, with eight in Los Angeles County and one in Marin County. The claims include negligence, failure to warn, defective design, negligent misrepresentation, fraudulent concealment and fraud, seeking damages for past and future economic and noneconomic losses.
