Abstract

The lack of scientific evidence of the safety and efficacy of over-the-counter topical cannabinoid-based cosmetics remains a concern. The current study attempted to assess the quality of cannabinoid-based cosmetic products available on the UAE market. In particular, the study attempted to quantify the presence of undeclared tetrahydrocannabinol, specifically delta-9-tetrahydrocannabinol (THC) and delta-9-tetrahydrocannabinolic acid (THCA), in these products. Methods: A total of 18 cannabinoid-based cosmetics were collected and analysed in this study. GC-MS analysis was used to determine the presence of total undeclared tetrahydrocannabinol. Results: The estimate for the average tetrahydrocannabinol content was 0.011% with a 95% CI (0.004-0.019). Leave-on cosmetics products are more likely to contain total tetrahydrocannabinol compared to rinse-off cosmetics (p = 0.041). Although there was no statistically significant difference in the total tetrahydrocannabinol according to cosmetic category, there was a tendency towards higher tetrahydrocannabinol content in the hand care products, baby products, and body care preparations. Conclusion: The current study reveals the need for producers of cannabinoid-based cosmetic products to issue quality certificates for each batch produced to inform users of the tested levels of tetrahydrocannabinol.
