The correct type of test to identify ecstasy is the Marquis test. This test is commonly used for presumptive identification of ecstasy (MDMA) and other drugs like amphetamines, opioids, and more. Here's how the Marquis test works:
1. A small sample of the substance suspected to be ecstasy is mixed with a few drops of the Marquis reagent.
2. The color change observed in the mixture indicates the presence of certain substances. For ecstasy, the Marquis reagent typically produces a dark purple/black color.
Remember, while the Marquis test can provide an initial indication of the presence of ecstasy, further confirmation through laboratory testing is necessary for definitive results.
