In the first paper of this series, a new detection method of marihuana constituents by the thinlayer chromatography with the solvent system of benzene-n-hexane-diethylamine (25 : 10 : 1, v/v) was described. In the present investigation it was studied whether any constituent of the plant allied with marihuana or of tobacco mixed usually in the actual samples interrupt the identification of marihuana or not. It was also investigated if this method could be applied to examination of the smoke of marihuana. As the results, any interruption by the plant extract described above was not recognized in the detection of marihuana. It was also found that cannabidiol, tetrahydrocannabinol and cannabinol were effectively detected in the smoke condensate of marihuana as well as in marihuana resin. Using this new detection method of marihuana, the authors succeeded in identifying the illegally used marihuana samples.
