Paper Abstract

Reports that money in general circulation is contaminated with cocaine have resulted in contaminated money theories purporting that any person carrying currency could potentially initiate a drug dog alert. Field tests on dozens of different drug detector dogs with widely varying breeds, ages and training regimes show a consistent threshold level of 1 - 10 (mu) g of methyl benzoate spiked along with cocaine on U.S. currency or 0.1 - 1 ng/sec methyl benzoate diffusion required to initiate an alert. No other substance studied to data has initiated consistent responses by the drug dogs studied.
