Cannabinoids are successfully extracted from a complex brownie matrix using the QuEChERS sample preparation technique, significantly reducing the presence of matrix interferences. The resulting clean samples are analyzed by GC–MS using a specialized deactivated GC column to provide heightened peaks for the cannabinoid compounds.
