Youth use of hemp-derived cannabis products containing psychoactive Δ8-tetrahydrocannabinol (delta-8-THC) is prevalent in the United States (US). Delta-8-THC is intoxicating, however delta-8-THC products are not subject to warning labeling requirements in many US states. This experiment determined effects of hypothetical cannabis warning labels on perception of delta-8-THC gummies and vape products. A mixed within-between-subject experiment was embedded into a 2023 survey of 3,647 Southern California adolescents.
