ABSTRACT:
Process and a test kit for the detection of drugs of methylenedioxy amphetamine family and derivatives, are disclosed. The process comprises (a) sampling sufficient amount of a material, suspected to be examined comprise of said methylenedioxyphenyl group; (b) admixing said sample with a sufficient amount of a strong acid reagent; and (c) detecting color gradual appearance and determining accordingly the presence of said methylenedioxy amphetamine drugs in predetermined interval of time. The test kit comprises a strong acid reagent; a color vs time chart comprising means for the detection of a specific drug by means of color and time of appearance, a reaction chamber wherein suspected material and said strong acid reagent are admixed and color is indicated; a sampler having means to collect sufficient amount of suspected material to be tested and to insert it to the reaction chamber.
