Abstract

In order to properly document the botanical features present in a sample submitted as suspected marijuana and to reduce the problems of the disposal of the hazardous wastes produced with the use of the Duquenois-Levine Test, a protocol is described that involves recording the morphological features of Cannabis found in a sample and two thin-layer chromatography systems for determining the cannabinoids present. This protocol provides more information on a sample than was obtained with other, previous protocols involving the Duquenois-Levine Test.
