INTRODUCTION: ∆-8 tetrahydrocannabinol (THC) is a psychoactive cannabinoid and structural isomer of ∆-9 THC that is technically legal under United States Federal law. Commercial ∆-8-THC products being sold are currently unregulated. This study aims to (1) describe the advertising and labeling of Δ-8 THC retail products; (2) compare the advertised amount of Δ-8 THC for each product to that found during independent laboratory analysis; and (3) evaluate the presence and amount of other cannabinoids in those products.
METHODS: Twenty ∆-8 THC products were purchased from retail stores in Pittsburgh, PA, USA. Samples were analyzed to determine cannabinoid content using a validated UPLC-MS/MS method. Descriptive statistics were calculated for all variables. Spearman's rank order correlation was calculated for the labeled ∆-8 THC content compared to ∆-8 THC content found on our analysis. Differences in continuous variables were compared using ANOVA, Wilcoxon Rank Sum, or Kruskal-Wallis tests.
RESULTS: ∆-8 THC was detected in 95% (N=19) of the sample products. A weakly positive correlation (Spearman's rho =0.40) was found between the advertised ∆-8 THC content and our analysis results. Factors associated with decreased difference in these variables included (1) solid matrix (chocolate, gummies) and (2) absence of a "lab-tested" label. Δ-9 THC was found in 35% (N=7) of the products, and CBD was found in one.
CONCLUSION: A majority of the products analyzed contained ∆-8 THC in amounts that could cause intoxication. The range of ∆-8 THC content on independent analysis was wide and weakly correlated to the advertised content. ∆-8 THC, ∆-9 THC, and CBD were the only cannabinoids detected.
