A lawsuit against a cannabis company alleging it uses deceptive marketing tactics to promote high-potency THC vape pens and cartridges to teenagers resulting in cannabis-induced psychosis is the first lawsuit of its kind and could present a legal threat to the growing industry.

The suit claims the cannabis brand STIIIZY IP has marketed to young users while failing to warn about users that the heightened potency of THC products could result in an increased risk of suffering cannabis-induced psychosis. Attorneys from Lieff Cabraser Heimann & Bernstein, Rouda Feder Tietjen & McGuinn and the Ribera Law Firm filed the action in Marin County Superior Court on Wednesday, alleging negligence, design defect, negligent failure to warn, fraud and breach of warranty against STIIIZY.
