Abstract

The University of Missouri used high pressure liquid chromatography plus mass spectrometry for a quantitative analysis of marijuana metabolites in blood and breath. A breath collector was developed for road-side sampling of human breath and subsequent laboratory analysis. The group also detected a previously unreported marijuana metabolite which is present in blood and breath for at least five days after smoking.
