A presumptive colour test for use on seized illicit materials has been developed for the detection of synthetic NBOMEs, a group of phenethylamine derivatives with potent hallucinogenic effect on consumption. The test is comprised of three reagents which are applied dropwise (3 drops each), sequentially, to a small sample of the unknown material in a well-plate. Within 5 min, the unknown substance will turn bright blue if a synthetic NBOME compound is present (positive), or will remain colourless for the reagent control (negative)
