Fooling a test kit?

[AuraithX]

I read in a bluelight post a few months ago that there is a certain chemical/herbal thing you can put in a pill to make the regnant tester instantly test positive for MDMA.

I think it was either phase_dancer or f&b that said it, anyone have any idea what I'm talking about?

There are quite a few substances that may give the impression MDMA is present when it's not. That's why its advised that several reagents be used to test a pill.
