This study presents a comprehensive method for the analysis of gas chromatograph (GC)-amendable pesticides in Cannabis flower. Furthermore, this method uses dispersive solid phase extraction (dSPE) to help mitigate matrix effects that are common in the flower extract. Three selected reaction monitoring (SRM) transitions were used for each target pesticide. This study was focused on developing a robust and sensitive method for GC amendable pesticides in Cannabis flower for use in the state of California. However, LC-MS/MS would also be required to analyze the complete California pesticide list.
