CLANDESTINE DIMETHYLTRYPTAMINE (DMT) LABORATORY
SEIZED IN HOLLYWOOD, CALIFORNIA

The Los Angeles Police Department’s Scientific Investigation Division (SID; Los Angeles) recently received two gallons of an aqueous, dark brown solution, presumed to be a natural product extract containing N,N-dimethyltryptamine (DMT; see Photo 1, Label A), and one liter of a clear solution suspected to be a solution of purified DMT (Label C). The exhibits were recovered from a clandestine laboratory located at a residence in Hollywood, California by the Los Angeles Police and the SID’s Hazardous Chemicals Team. A glove box and filter apparatus (not shown) were also seized. Of note, several of the first responding officers were made ill by chemical odors while securing the laboratory. The dark brown solution was basified with 10 percent ammonium hydroxide, and extracted with chloroform; analysis of the extract by GC/MS confirmed DMT (not quantitated, but estimated to be roughly 5 percent in the original solution). Analysis of the clear solution by GC/MS and color testing (Marquis (brown) and nitroprusside (negative)) confirmed DMT in naphtha (not quantitated, but again estimated to be roughly 5 percent). The off-white, crystalline powder labelled as “B” shows DMT that was extracted from the dark brown solution and recrystallized from chloroform. The laboratory operator was apparently isolating DMT via naphtha extraction of a natural product, possibly Mimosa hostilis root. This is believed to be the first ever DMT clandestine laboratory in Los Angeles.

"GANJA BUTTER" IN FAYETTEVILLE, ARKANSAS

The Arkansas State Crime Lab (Little Rock) recently received a multi-exhibit submission including: A) A plastic storage container containing a cloudy brown liquid (430.0 mL) with brown sediment (see Photo 2) and three plastic storage containers containing a bi-layer consisting of a soft green solid (top) and a cloudy brown liquid (bottom), suspected to be a prepared form of marijuana called “ganja butter” (see Photo 3); and B) Five sugar cubes and a white crystalline substance (a crushed sugar cube), all suspected to contain LSD (no photos). The items were seized by the Fayetteville Police pursuant to a warrant search of a local residence (no further details). The suspects in the case provided the arresting officers with a copy of the recipe they used to prepare the “ganja butter.” The cloudy brown liquids had no odor, whereas the green solids had the odor of sour milk. The layers were sampled and tested separately. After acid/base workup, filtration, and extraction with methylene chloride, the extracts were analyzed by GC/MS and TLC. The brown cloudy liquid with sediment was confirmed to contain a small amount of Δ9-tetrahydrocannabinol (THC; not quantitated). All three green solids from the bi-layer exhibits (total net mass 928.7 grams) were also confirmed to contain THC (not quantitated but a moderate loading based on the TIC). However, the liquids from the bi-layer exhibits (total net volume 756.0 milliliters) were found to contain no controlled substances. The green, solid material was not plant material, but rather was the residue of the butter after the cook. This was the first submission of this type to the laboratory. The six sugar samples all fluoresced when viewed under UV light. After acid/base workup and extraction with methylene chloride, analysis by GC/MS and TLC confirmed LSD in five of the six exbibits (not quantitated, but a low concentration based on TIC); one of the cubes had only trace LSD, not confirmed. The laboratory receives LSD sugar cubes roughly once a year.

VERY LARGE SEIZURE OF ECSTASY TABLETS (INCLUDING FAKES)
AT THE BLAINE PORT OF ENTRY, WASHINGTON

The DEA Western Laboratory (San Francisco, California) recently received 11 large, heat-sealed evidence envelopes containing a large number of tablets (total net mass approximately 72 kilograms), suspected Ecstasy (see Photo 4; closeups not available). The exhibits had been concealed in a false gas tank of a vehicle entering at the Blaine, Washington Port of Entry, and were seized by Immigration and Customs Enforcement agents. One envelope contained 8,729 green, biconvex tablets with a Batman logo (average mass 256 milligrams), 3,605 pale blue, flat beveled tablets with a dolphin logo (average mass 177 milligrams), and 164 pale blue, flat beveled tablets with a heart logo (average mass 178 milligrams). Analysis of the tablets by GC/MS and Marquis color testing confirmed MDMA in the green tablets (45.7 milligrams per tablet), but indicated no controlled substances in any of the blue tablets. Further analyses of the blue tablets by GC/FID affirmed no controlled substances and no basic or neutral soluble components. The tablets in the other 10 envelopes all contained MDMA. This was one of the largest ever submissions of Ecstasy tablets (but also the first submission in some time of Ecstasy tablet fakes) to the Western Laboratory.

HEROIN SMUGGLED IN SANDALS IN MEMPHIS, TENNESSEE

The DEA North Central Laboratory (Chicago, Illinois) recently received one single and one intact pair of women’s sandals, each containing a rectangular package of hard brown material hidden in their heels, suspected heroin (see Photo 5). The exhibits were seized by U.S. Immigration and Customs Enforcement personnel at an express mail hub in Memphis, Tennessee, and were en route from Mexico to Illinois. The sandals displayed no signs of tampering; the packets were wrapped in clear plastic and black carbon paper. Analysis of the brown material (total net mass 528.1 grams) by GC/FID, GC/MS, FTIR, and color tests confirmed 55 percent heroin hydrochloride, along with acetylcodeine, acetylmorphine, and papaverine (minor alkaloids not quantitated). This is believed to be the first submission of heroin smuggled in sandals to the North Central Laboratory.

UNUSUAL COCAINE BRICK IN NEW YORK, NEW YORK

The DEA Northeast Laboratory (New York, New York) recently received a kilogram size brick of compressed brown powder containing small white specs, suspected cocaine (see Photo 6). The brick was seized in New York City by agents from the New York Field Division (details not provided). Analysis of the powder (total net mass 1005 grams) by GC/MS, GC/FID, and FTIR/ATR confirmed 72.3 percent cocaine hydrochloride, adulterated with procaine hydrochloride, hydroxyzine, and diltiazem (adulterants not quantitated). The white specs were not isolated for separate analysis. The brick was somewhat unusual in its coloration, mixture of pharmaceutical adulterants, and presence of white specs. This is the first such submission to the Northeast Laboratory.

UNUSUAL CLANDESTINE AMPHETAMINE LABORATORY IN GUADALAJARA, MEXICO

The DEA Special Testing and Research Laboratory (Dulles, Virginia) recently received three exhibits from a clandestine amphetamine laboratory in Guadalajara, Mexico (seizure details not provided). One exhibit was an off-white, lumpy powder, while the other two were amber to canary yellow, crystalline powders (see Photo 7). Analysis of the white powder (total net mass 17.5 grams) by GC/MS, FT/NMR, CE/UV, and FT/IR indicated 100 percent d,l-amphetamine hydrochloride. Analysis of the two yellow powders (total net mass 16.3 grams) by the same methods indicated 99 percent 1-phenyl-2-nitropropene. The synthetic route was not determined (there are several published procedures that detail the conversion of the 1-phenyl-2-nitropropene to either phenylacetone or directly to amphetamine). These are the first submissions of these types to the Special Testing and Research Laboratory.

SHAM COCAINE IN RICHMOND, VIRGINIA

- Packaged as "Room Odorizers" -

The DEA Mid-Atlantic Laboratory (Largo, Maryland) recently received 5 ziplock plastic bags, all labelled as “N St Room Odorizer” and containing white powder and bricks of compressed white powder, all suspected to be sham cocaine (see Photos 8 and 9). The bricks were irregularly shaped and had no logos. The exhibits were confiscated by DEA agents during a traffic stop in Richmond, Virginia, and it is suspected that they were going to be employed as a “drug rip,” because there is a cocaine shortage in the Richmond area. Analysis of the powder by GC, MS, and IR indicated a mixture of benzocaine and lactose in four of the bags (total net mass 4,007 grams), and a mixture of benzocaine, procaine, caffeine, and mannitol in the fifth bag (total net mass 1,027 grams); the various components were not quantitated. The Mid-Atlantic Laboratory has encountered similar mixtures of non-controlled substances packaged as room odorizers in two other cases.
