Simple field test for marijuana.
A simple, rapid, sensitive, and specific field test for marijuana and its products is described. The test employs an extracting-eluting ssolvent and an inert adsorbent microcolumn coated with Fast Blue B salt as the reagent. One milligram or less of the suspect material can be tested within 1 min. Of greater than nonmarijuana plant samples tested, only nutmeg and its mace responded similarly to marijuana initially. A differentiation was possible by careful evaluation of the colored microcolumn and the elution behavior of the colored products. The test also provides for a confirmatory step, based on spectrophotometric analysis of the colored eluates. The reagent microcolumn was very stable to environmental factors such as moisture, light, and air.
