ABSTRACT

Introduction: A recent law (DCTO-2020-883-APN-PTE-Law No. 27,350. Regulation) passed in Argentina put an end to the ban imposed for the last 60 years on cannabis cultivation within the country. The law permits restricted access to cannabis derivatives for medicinal, therapeutic, and palliative use by individuals and communities, allowing self- and community-based cannabis production. This is cause for concern in view of the lack of quality controls for cannabis derivatives. The several varieties of cannabis grown in Argentina have different chemical profiles and are processed in a variety of ways-mostly by alcohol extraction or maceration at different temperatures and for different amounts of times-making the cannabinoid content of these preparations highly variable. Determining the characteristics of home- and community-grown cannabis products will facilitate the implementation of public policies conducive to their safety and improvement. Objective: The aim of this study was to determine the cannabinoid chemotypes used for therapeutic purposes in Argentina and evaluate whether the cannabinoids present in homemade derivatives are comparable to those in commercially available products. Materials and Methods: High performance liquid chromatography with ultraviolet and diode array detector (HPLC/UV-DAD) analysis of 436 samples (oils, resins, and inflorescences) was carried out to determine the identity and concentration of five cannabinoids: tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiolic acid (CBDA), cannabidiol (CBD), and cannabinol (CBN). From three different sources, the samples represent the type of medical cannabis preparations to which patients have access. Results: The results indicate that the medium-to-low cannabinoid concentration in a significant number of homemade oil samples is similar to that found in commercial products. Most of the samples have a THC/CBD ratio >1 or only contain THC. Acidic cannabinoids were detected in homemade preparations, but were not reported in package inserts of commercial products. Conclusions: Our results indicate that despite their considerable variability, homemade preparations as a whole show cannabinoid levels and profiles equivalent to the commercially available products commonly used for medicinal, therapeutic, and palliative purposes in Argentina.
