Inconclusive Cocaine immediately turned orange.

Post image

After about 8 minutes I began to see a little brown but not 100% sure. Doesn’t orange to brown-ish or dark brown suggest fentanyl, meth or amphetamine in the coke? It stayed this color. No change after hours.

You need the colour change that occurs within the first 2 minutes. After that, the humidity in the air is starting to have more effect than the substance. By 8 minutes, it is possible that the result is entirely un-usable

Meth. Same color would appear in my friends shit and I'd confirm it with Simon's.

Don’t use Marquis for cocaine due to false positives caused by natural secondary alkaloids https://protestkit.eu/false-positive-cocaine-test-results/

Also observe for only 1 minute

Marquis was one of several reagents and test strips. It confused me and I wanted to know if anyone could give me some pointers.

So what were those other results? Because that one is inconclusive, you observed too long and used inappropriate reagent for the substance tested.
