test results...

[gaze]

Alright, I need some opinions:

I tested a pill with the marquis (eztest) and it turned black. Rather than move through the blue/purple stages, though, it looked brown first, then black and appeared to be "muddy" or brownish around the edges (especially when spreading the liquid out over the plate, trying to find blue)

When I tested it with the Simons, it turned bright blue instantly.

So am I dealing with a methbomb here or is it possible that it's mdma based on the black/brown eztest results? I know that other (mdxx) pills I've tested have turned pretty obviously purple before appearing black so I just wanted to get an idea of what you guys thought.

thanks!

MDMA + meth seems pretty likely, but it's impossible to call it for sure. It wouldn't be a bad idea to test your marquis reagent with an aspirin - it's working properly if the reaction color is red.

Thanks, I actually just looked at ecstasydata and they've updated their site with a pill that looks and weighs exactly the same as the one I tested (same geographic area)

would ephedrine cause a false "brown" positive?

According to PhreeX's list (the only source I can find which lists a Marquis RXN for ephedrine), that could be. He listed the RXN for ephedrine as being "yellow to yellowish brown."

The document I'm referring to used to be posted in this forum once upon a time, but seems to be gone now.

That document was an excellent resource, i think there's a similar list in one of the pill testing pages at erowid. edit: hereitis, but it doesn't include ephedrine. http://www.erowid.org/chemicals/mdma/mdma_faq_testing_kits.shtml

Maybe a bluelight mod can dig up phreex's list??

There's very little on it not listed in more detail in the Erowid document. Also, it contains at least one error, claiming a Marquis reaction for cocaine, which, according to Easy E, should not cause a reaction.
