probably not. there is a specific Marquis reagent just for testing for cocaine. it is not the same as is in EZ Test. maybe there is a reaction buti doubt you could depend on it...
oh i found this... this list was collated by phreex and hasn'tbeen independently verified. http://www.bluelight.ru/ubb/Forum14/HTML/000234.html
basically it means you can't really tell.

hmmm hasn't anyone heard of web search engines?
here's what i did to find this in 5 seconds...
typed www.google.com
typed "cocaine marquis reagent kit" in the search field.
clicked on the top result: http://www.crime-scene.com/ecpi/serology_drug.html
5 seconds in total... and this is what i do everytime someone asks me a question like that... and i, as the middle man, don't mind being cut out
update: the 6th link down gave me it's proper name: "Cobalt-Thiocyanate Reagent"
