Abstract

The behavioral and physiologic effects of single, intravenous bolus doses of cocaine in 5 male human subjects were correlated with cocaine levels in saliva and blood. All measures were performed under double-blind conditions. Two test doses of cocaine (15 mg and 40 mg) and one placebo test dose were administered to each subject in a random, cross-over design. Each test day was separated by a minimum of 48 h. Cocaine levels in saliva and blood significantly (p $ 0.05) correlated with responses on self-rating scales for drug sensation (Feel Drug scale), psychotomimetic effects (LSD scale), and feelings of rush (Rush scale). Significant (p $ 0.01) correlations also were obtained with cocaine biofluid levels and pulse rate. The close relationship observed between cocaine saliva levels and cocaine-induced behavior and physiologic effects presents the opportunity for development of a new noninvasive method for detection of current cocaine use.
