I just tested some pills and they turned up black and orange for the Marquis test. Also did the Mecke and Simon's and they showed green/black and blue respectively. I was thinking that these results mean that it was a speed/mdma combo but on the instructions it states that ,"Marquis reagent will also detect speed, but only in the absence of an ecstasy-like drug" So if the Mecke test showed a positive for MDxx then would this mean that the Marquis results are invalid? This is a dancesafe kit btw...
