What field test is used for cocaine?

The Scott Reagent is specifically designed for the field testing of cocaine. When a sample suspected to contain cocaine is treated with Scott Reagent, it undergoes a distinctive color change. Initially, the solution may appear blue indicating the presence of cocaine, and a subsequent step may show the classic double-layer blue color when a specific process is followed, confirming the drug’s identity.

This makes Scott Reagent particularly reliable for identifying cocaine in field situations where quick results are needed. Other tests, like the Marquis Reagent, are generally used for different substances, such as detecting opiates or other narcotics, and the Duquenois-Levine Test is utilized mainly for marijuana. The LSD Test is specifically made for detecting the presence of LSD and would not yield results for cocaine. Thus, the specificity of the Scott Reagent for cocaine makes it the correct choice in this context.
