The case traces back to September 2024, when a woman named Jenna Combel filed suit in state court claiming she suffered paralysis and nerve damage from inhaling nitrous oxide she purchased from Tahoe, among other defendants, between 2019 and 2023. In her complaint, Combel described nitrous oxide inhalation as producing euphoric, dissociated, and out-of-body experiences, and alleged that the substance is commonly sold and used as a recreational drug known as whippets, poppers, or laughing gas. She sued Tahoe and twenty other alleged distributors and manufacturers.
