In this study, we developed and validated a liquid chromatography tandem mass spectrometry (LC-MS/MS) method for the simultaneous determination of eight phytocannabinoids in various cannabidiol (CBD) products from Japanese market. This method was combined with electrospray ionization in positive mode and sample preparation with QuEChERS. Three types of commercial products such as honey, chocolate, and gummies were used to perform accurate quantification with unified protocol of LC-MS/MS and QuEChERS. The limit of detection and quantification were 5-20 µg g
