MARIHUANA CONTACT TEST, EVALUATION AND DEVELOPMENT
A colorimetric swab test for detecting human contact with marihuana was evaluated. The test was found to be capable of detecting only 83% of marihuana smokers immediately after smoking and was also demonstrated to be subject to a wide range of possible interferences. An alternative test was developed using thin-layer chromatography as the method for detecting marihuana constituents from a skin swab. This test detected 86% of the smokers immediately after smoking and was not demonstrated to be subject to any interferences. Recommendations are presented on practical uses for this test.
