All samples were diluted by a factor of 25 in Methanol for HPLC analysis (40 µL sample in 1.00 mL MeOH). The samples were run on an Agilent 1220 HPLC equipped with a variable wavelength detector set to monitor 230 nm. A full description of the RP-HPLC program used for cannabinoid quantification may be found in the supplementary information. The peak integration and analyte concentration was performed in Microsoft Excel. The original file is supplied with the supporting information.
