E2 may change color in the presence of PMA but so does Marquis, no colorchange with PMA.
So if your pill contains PMA only, either EZ Test Classic or (for instance E2) will do fine.
However, the problem currently is the fact that combinations of drugs appear in one pill, for instance PMA and MDMA which could be deadly (just take a few...)
These kind of combinations can now be detected with EZ Test X-TREME.
