title: The pharmacological effect of fractions obtained by smoking cannabis through a water-pipe. II. A second fractionation step.
abstract: The catatonic activity, prolongation of phenobarbital sleeping-time, convulsant action and disruption of nest-building activity was assessed in mice subjected to 4 cannabis pyrolysis products and their tobacco analogues. All but one of the cannabis fractions prolonged the pentobarbital sleeping-time and disrupted the nest-building activity of mice in a way not related to their content in the main cannabinoids. Nest-building activity seems to be the most valid assay we have used so far.
