What is the color of the Marijuana test kit?

Explanation:
The color change you look for with cannabis in field presumptive tests comes from the Duquenois-Levine reaction. When cannabinoids are present, this reagent turns purple. So the marijuana test kit should read purple. Keep in mind this is a presumptive result—lab confirmation is needed for a definite identification. The other colors listed don’t match the standard cannabis reaction for these common kits.
