We developed a new marijuana field test kit that can discriminate ⊿9-tetrahydrocannabinol (⊿9-THC), cannabidiol (CBD), and cannabinol (CBN) using thin-layer chromatography (TLC). The kit pre-colors the samples at the time of extraction prior to development by TLC, thereby improving the ease and speed of operation at the investigative site. Using this kit, ⊿9-THC in the sample could be detected in approximately 10 minutes.
