The subject invention provides colorimetric test strips and fast screening field test kits for differentiating between cannabinoids in cannabis samples, preferably, for differentiating marijuana from other cannabis plants, e.g., hemp. The fast screening field test kit can also be used for confirming the presence of marijuana in a complex cannabis sample. The colorimetric test strips use a solid substrate (e.g., capillary microextraction of volatiles (CMV) device) for the colorimetric reaction. The non-polar nature of the CMV sorbent does not allow the reaction of FBBB and THC to spread, producing an intense red color in the presence of a plant with high concentration of THC (e.g., marijuana) or an orange color in the presence of a plant with a high concentration of CBD (e.g., hemp).
