Color Test Reagents/Kits for Preliminary Identification of Drugs of Abuse (pdf)

From National Institute of Justice - Law Enforcement and Corrections Standards and Testing Program - U.S. Department of Justice.

A document by the drug warriors detailing reactions to common legal and illegal substances with 12 (!) different field test kits. Requires some cross-tabulation to read the charts and doesn't include any new research chemicals on the market since 2000. Mandelin is reagent A.4, Marquis is reagent A.5, Mecke is reagent A.10, and Simon's is reagent A.12. This is what the FBI, DEA, and US Sherriffs use to identify suspected drugs they've found, and what they recommend to local and state law enforcement agencies.
