- Abstract
This research investigated using Fast Blue B (FBB) [o-Dianisidine bis (diazotized) zinc double salt] to develop fingerprints contaminated by the active constituents of Cannabis sativa L. Cannabis-contaminated fingerprints were placed on various porous and nonporous surfaces and were processed with FBB. Specificity tests (using 50 volunteers) and 100-day aging tests were conducted on white paper. The FBB solution developed the contaminated fingerprints on each surface, as well as on all samples during the aging test. The specificity tests had no false-positive reactions, which suggests the potential use of FBB in cases where an association of the actual drug handling, versus drug container handling, is desired.
