    Hi all, perhaps this sub can use some nice examples of reagent testing tips 'n tricks =)

    Let's start with false positives! For example did you know that the Scott reagent (Cocaine Test) gives a false positive with A-PHP, A-PIHP and PV9?

    These cathinones are known for serious nasty side effects, are extremely potent stimulants with tendencies for psychosis and binges. The police use Scott as a single-reagent Cocaine kit, but don't try to do the same with unknown powders! Always test your Coke with more than a single reagent.

    Do you have examples of other substances easily mistaken with a reagent test? We will be posting on regular basis in this thread.

    So here we have another one, according to the Slovenian Police MDPHP gives a complete false positive (unless you are a pro) for MDMA.

    What's even more interesting is that we have some MDPHP, confirmed by LC/MS-QTOF analysis and it does NOT react that dark, though. Can anyone try to confirm?
