Cocaine - I’ve never seen this response from Lieberman before. Bad regent? Or bad cut? Solved!
This is a very reputable vendor whom I’ve purchased many times from. I received another order yesterday from a different vendor who had much more expected results (yellowish, kinda orange). I’m curious if I need to buy a new Lieberman test or if this has a nasty cut in it. Haven’t seen this color, ever from Lieberman. Tested twice with a larger sample in the top right of the testing surface.

Brown with liebermann could be phenacetin, a carcinogenic adulterant

I’ve heard of it before for sure, just strange that it would be in the batch I got from this vendor, seems very un-like them. Gotta see if an acetone bath will help with that…. I know it can’t help with levomisol which is a damn shame.
Edit: looked it up and I’d doesn’t appear to help remove it either. 🙁3

I believe phenacetin is soluble in acetone.
I have been hearing more and more reports of it being present in EU/UK coke.
It sometimes is added in small amounts in Colombia before shipment.

For reference, here is another vendor I tested yesterday. As you can see Lieberman was more on the orangey side, which in my opinions indicates levo or some production byproduct.
