The Marquis test is the original Ecstasy testing kit and was the first ever available to the public. It is the first step in the EZ test range to indicate the presence of Ecstasy. The Marquis test will turn a different colour for any of the Ecstasy-like substances MDMA, MDA, MDE, MBDB, DXM, 2C-B, Amphetamine plus also DOB, DOI, Methylone, Butylone, Naphyrone and Opiates. The information sheet and colour chart included, should correspond to these various substances.
