HARM REDUCTION FAQ

Understanding the science, methodology, and practical role of qualitative analytical kits in community health. Knowledge is the ultimate form of protection.

Yes — an instant deep purple to black reaction with Marquis is the textbook positive for MDMA/MDA. What you're looking for is a rapid, bold color change within the first 5-10 seconds. If it fizzles, stays clear, or produces a weak yellow/orange instead, you likely have a different substance. We always recommend following up Marquis with Simon's reagent to differentiate MDMA (secondary amine → blue) from MDA (no reaction), and Froehde for a third confirmation point.
