Marihuana was analyzed for its major constituents, cannabidiolic acid, cannabidiol, tetrahydrocanabinol, and cannabinol, by treating the petroleum ether extract with diazomethane. The methyl esters so produced, together with the unchanged components, were subjected to gas chromatography on a polar silicone column.
