The exchange of illicit cocaine for money by drug dealers is an everyday occurrence in cities in the United States. There is ample opportunity during the exchange, storage, and use of cocaine for paper currency to become contaminated. Because currency is exchanged frequently, it is likely that contaminated currency would be found in common use. We examined ten single dollar bills from several cities in the United States for the presence of cocaine. Individual bills were extracted with methanol… Expand

The Quantitation of Cocaine on U.S. Currency: Survey and Significance of the Levels of Contamination
To investigate the extent of contamination of currency samples, a mathematical model was developed based on the background survey that indicates the likelihood of drawing a bill in specific concentration ranges that had significantly higher contamination than currency in general circulation. Expand

Screening for cocaine on Euro banknotes by a highly sensitive enzyme immunoassay.
A comparison between the amount of cocaine extracted by cotton swabbing of one square centimeter of the banknote showed a good correlation for lower contamination levels, and a sensitive direct competitive immunoassay showed high sensitivity of detecting pg of cocaine per 1cm2 of one banknote.

We developed a sensitive and specific assay for the simultaneous measurement of cocaine, cocaethylene, six of their metabolites, and anhydroecgonine methyl ester, a pyrolysis product, in biologicalExpand
Free‐base cocaine smoking
Six healthy male, paid subjects smoked 50 mg of free‐base cocaine in a specially designed glass pipe under a rigidly controlled smoking protocol and the cocaine free base inhaled induced psychological and cardiovascular effects similar to, or slightly more intense and pleasurable than, the effects of 20mg of cocaine HCl (18 mg of cocaine base) taken intravenously by the same subjects.
