Fast analysis of cannabis samples without prior sample preparation or chromatography was performed using desorption atmospheric pressure photoionization‐mass spectrometry (DAPPI‐MS). The MS 2 spectra of the molecular ions of tetrahydrocannabinol (THC) and cannabidiol (CBD) formed in DAPPI‐MS showed distinct product ions, unlike the protonated molecules formed with other ambient mass spectrometry techniques, making possible the reliable identification of THC from cannabis samples.
