Reddit mentions of NIK Drug Test Kit - M Methaqualone (Box of 10)

Hi, I'm not saying I don't believe you because you seem very knowledgeable about this subject, but I have an anecdote that contradicts what you're saying and I'd be interested to hear your explanation for why this happened. I ordered "methaqualone" from a vendor on SR2 about 6 months ago (FlatBushZombies, he pulled an exit scam and is no longer vending I'm pretty sure) and I used a NIK reagent test kit like this one.. It turned blue indicating a positive result for the presence of methaqualone and the information sheet that came with the test said that a false positive would only occur if there was PCP present which I doubt was the case based on my experience when I took it. Did I just get lucky and get the real deal or can certain analogues also test positive on tests like that?
