MECHANICAL PREPARATION OF CONCENTRATED CANNABIS
IN SALT LAKE CITY, UTAH The DEA Western Laboratory (San Francisco, California) recently received a 2-pound ziplock plastic bag commercially labeled as brown sugar, and containing a light brown, crystalline powder, presumed sucrose (see Photo 13). Hidden within the powder were two smaller ziplock bags, each containing a darker brown material, suspected marijuana (see Photo 14). The exhibit was seized by investigators at an express mailing facility in Salt Lake City, and was submitted by the DEA Salt Lake City Resident Office. The light brown, crystalline powder in the large bag was identified as sucrose. Analysis of the darker brown material in the smaller zip-lock bags (total net mass 55.2 grams) by GC/MS confirmed delta-9-tetrahydrocannabinol (THC, not quantitated); however, no cannabinol, cannabidiol, or cannabichromene was identified. Stereomicroscopic examination showed fragmented trichromes, and it is suspected that the material had been sieved to remove resin and trichromes (see Photo 15). The Western Laboratory has previously received similar exhibits of this form of marijuana.
