Odor impact of volatiles emitted from marijuana, cocaine, heroin and their surrogate scents.

Somchai Rice1, Jacek A Koziel1.   

Abstract

Volatile compounds emitted into headspace from illicit street drugs have been identified, but until now odor impact of these compounds have not been reported. Data in support of identification of these compounds and their odor impact to human nose are presented. In addition, data is reported on odor detection thresholds for canines highlighting differences with human ODTs and needs to address gaps in knowledge. New data presented here include: (1) compound identification, (2) gas chromatography (GC) column retention times, (3) mass spectral data, (4) odor descriptors from 2 databases, (5) human odor detection thresholds from 2 databases, (6) calculated odor activity values, and (7) subsequent ranking of compounds by concentration and ranking of compounds by odor impact (reported as calculated odor activity values). For further interpretation and discussion, see Rice and Koziel [1] and Rice [2].

Specifications table Value of the data This data is the most comprehensive summary of volatiles emitted from real and surrogate scents of marijuana (221, 78), cocaine (153, 15), and heroin (41, 19), respectively, to date. This data includes organoleptic percepts from 2 known databases, odor detection thresholds from 2 benchmark databases, significant ions from mass spectral data, and calculated odor activity values (OAVs, if available) for each compound. This data shows rank of drug volatiles by concentration in relation to the rank by odor impact (as calculated OAV). Odor activity value data can open up new ways of forensic drug analysis. Data from previous research on canine odor detection thresholds (ODTs) is reported for further insight, highlighting differences with human ODTs and needs to address gaps in knowledge.

Data

CAS Registry Number

A CAS Registry Number is a unique numeric identifier that corresponds to only one substance. The CAS has no chemical significance, but can be used as a link to more information about a specific chemical substance [3]. CAS number is useful to identify a compound that has multiple synonyms. CAS numbers were used in all data tables in this report.

Odor Detection Threshold (ODTs)

Published ODT values are not fixed numbers, but are set to represent the lowest concentration that 50% of the population can detect [4]. For the purposes of calculating odor activity values, standardized human ODTs from Devos et al. [5] were used when available. The compilation from Devos et al. contained a total of 2075 ODT values in air for 641 chemical compounds, gathered from 372 references. ODTs were weighted and averaged [5]. If ODT for a compound was not given in Devos et al., the LRI Database [6] was used. LRI database contains 1500+ records on ODT and odor percepts [6]. ODTs for canines were compiled from previous literature. See Rice and Koziel [1] for full discussion on human and canine ODTs. ODTs were used in reporting data in Table 1, Table 2, Table 3, Table 4, Table 5.

If two references of ODTs are available, ODT from Devos, et al. [5] is used to calculate OAV. RT = Retention Time. ODT = Odor Detection Threshold. Code, see Section 1.5. Models = significant ions used for identification/semi-quantitation, # before colon is number of significant ions, #’s after colon are m/z. Net % match as calculated using AMDIS and target specialty mass spectral libraries. PAC = Peak Area Counts, and refers to relative abundance as given by the mass spectral detector. OAV = Odor Activity Value, and is calculated as ratio of PAC: OAV. Underlined items highlight the compounds found in Pseudo Scent Marijuana. + Compounds indicate confirmation with reference standards, matching retention time and spectra.

If two references for ODTs are available, ODT from Devos, et al. [5] is used to calculate OAV. RT = Retention Time. ODT = Odor Detection Threshold. Code, see Section 1.5.

If two references for ODTs are available, ODT from Devos, et al. [5] is used to calculate OAV. RT=Retention Time. ODT=Odor Detection Threshold. Code, see Section 1.5. Models=significant ions used for identification/semi-quantitation, # before colon is number of significant ions, #’s after colon are m/z. Net % match as calculated using AMDIS and target specialty mass spectral libraries. PAC = Peak Area Counts, and refers to relative abundance as given by the mass spectral detector. OAV = Odor Activity Value, and is calculated as ratio of PAC: OAV. Underlined items highlight the compounds found in Pseudo Scent Heroin. + Compounds indicate confirmation with reference standards, matching retention time and spectra.

Column retention time in chromatography

Column retention time (RT, min) is the time between sample introduction via thermal desorption in the gas chromatography (GC) inlet and the analyte peak reaching the mass spectrometer and/or sniff port at the end of the analytical column. It was not appropriate to use retention indexes (Kovats RI) for identification because: (1) the non-polar and polar columns were connected in series when analyzing in multidimensional GC; (2) use of indices of medium polarity column could lead to large errors for compounds that are affected by one of the columns more than the other. Known retention times of standards previously analyzed on this system were used for compound identification, and indicated by + symbol in Table 3, Table 4, Table 5. RTs are also reported in Table 3, Table 4, Table 5.

Aroma descriptors

Aroma descriptors were compiled from Flavornet and The Good Scents Company. Flavornet has aroma descriptors from 738 compounds, compiled from studies using GC-olfactometry [7]. The Good Scents Company is dedicated to providing organoleptic information to the flavor, food and fragrance industry [8]. Aroma descriptors from these 2 databases were used in reporting data in Table 3, Table 4, Table 5.

Sample code

Aromas were characterized by human nose from volatiles emitted into the headspace of illicit marijuana, cocaine, and heroin. Various states of seizure were examined: (1) 50 kg of marijuana in a cloth military style duffel bag (Sample Code A1–A3); (2) 1 g marijuana packaged in a plastic zip-top sandwich bag (Sample Code A4–A5); (3) 1 g old, desiccated marijuana with no packaging (Sample Code A6–A7); (4) plastic zip-top sandwich bag with 1 g marijuana removed (Sample Code B1–B4); (5) 1 g crack cocaine packaged as tear drops (Sample Code D1); (6) 1 g cocaine adulterated with Levamisole (Sample Code D2); (7) 1 kg evidence pack containing cocaine (Sample Code D3); (8) 1 g cocaine in an opened plastic bag (Sample Code D4–D5); (9) 1 g heroin seized in 1997 (Sample Code F1); (10) 1 g heroin seized in 2010 (Sample Code F2). Sigma Pseudo™ Narcotic Scent Marijuana formulation (Fluka, #P7309) (Sample Code C1–C3), Sigma Pseudo™ Narcotic Scent Cocaine formulation (Fluka, #P2423) (Sample Code E1), and Sigma Pseudo™ Narcotic Scent Heroin formulation (Fluka, #P2548) (Sample Code G1) were purchased from Sigma-Aldrich (St. Louis, MO). These sample codes were used in reporting data in Table 3, Table 4, Table 5.

Target mass spec libraries, models, and net % match, peak area counts

AMDIS (NIST, Gaithersburg, MD) software was used for identification of unknown compounds. Six specialty mass spectral libraries were used for compound identification: NISTEPA (1086 compounds in the EPA’s ‘list of lists’), NISTDRUG (739 compounds in the Canadian AAFS Toxicology Section MS Database Committee and the Association of Official Racing Chemists libraries), NISTFF (991 compounds in the Philip Morris Flavor and fragrance collection), NISTTOX (1213 compounds represented in Finnigan Corporation’s Toxicology library), NISTFDA (415 compounds in an FDA collection of mass spectra), and NISTCW (62 compounds relevant to detection of chemical weapons). A model is the mass-to-charge ratio (m/z) of a deconvoluted peak, and are listed in order of highest to lowest relative abundance. For example, under a ‘Models’ column heading, 2: 58 88 signifies 2 models with m/z 58 and 88 were used for identification. Net % Match is the final match quality value (100=perfect match) between the deconvoluted component and the target library spectra. The minimum match value was set at 65 for all analysis of this data. Peak area counts (PAC) refers to the relative abundance of the analyte, or the area under the chromatographic peak. The mass detector was assumed to have equal response factors for each compound, for the purposes of calculating OAV. These parameters were used in reporting data in Table 3, Table 4, Table 5.

Odor activity values (OAV)

OAV is defined as the unit less ratio of concentration of a compound in gas phase to the odor detection threshold. For illustrative purposes, the PAC was used for the concentration value of each compound. See Rice and Koziel [1] and Rice [2] for further discussion on OAV. This ratio was used to calculate the OAVs reported in Table 3, Table 4, Table 5.

Ranking definitions

Compounds from each drug were ranked by concentration (highest concentrated=ranked #1) and then by calculated OAV (highest odor impact=ranked #1). In most cases, there was no apparent correlation between chemical concentration and odor impact, i.e., rank #1 by concentration did not usually rank as 1 by OAV. This ranking and sorting was used to report data in Table 6, Table 7, Table 8.

Methodology

Carboxen/PDMS, 85 μm Stable-flex, 24 gauge SPME fibers were used (Sigma-Aldrich, St. Louis, MO, USA). Briefly, experimental conditions were as follows: drugs were placed in separate, pre-cleaned and oven-baked 16 ounce mason jars with modified lids. The Carboxen/PDMS SPME fibers were exposed to the headspace and volatiles were passively extracted; equilibration time was the same as extraction time (1 h at ambient temperature). When the extraction step was completed, the SPME fiber was retracted, wrapped in pre-baked aluminum foil, placed in a pre-cleaned mason jar, and transported back to the laboratory in a cooler on ice. In the laboratory, fibers were stored as described above in a 4 °C refrigerator pending placement into the heated injection port of the MDGC-MS-O for thermal desorption and analysis. MDGC-MS-O analysis was performed on an Agilent 6890 GC, with a restrictor guard column, non-polar capillary column (BP-5, 56 m × 530 μm inner diameter × 1.00 μm thickness, SGE, Austin, TX, USA) and polar capillary column (BP-20, 25 m × 530 μm inner diameter × 1.00 μm thickness, SGE, Austin, TX, USA) connected in series. Outflow from analytical column was held at 7.0 cc/min. Sample flow was split 3:1 via open split interface to the sniff port and mass spectrometer, respectively, as determined by restrictor column inner diameter. Desorption time was 2 min in splitless mode at 270 °C under flow of helium carrier gas (99.995% purity). Analysis of the same fiber immediately after sample injection, revealed no carry over, with all compounds desorbed in the initial analysis. The oven temperature was programmed as follows: 40 °C for 3.00 min, then increased to 220 °C at a rate of 7.00 °C per min, and held for 11.29 min (40 min total run time). The carrier gas was set at constant pressure at the midpoint (junction point of the non-polar and polar column) at 5.8 psi. Transfer line to the MS was set at 240 °C; transfer line to the sniff port was set at 240 °C with humidified air set at 8.00 psi. MS heated zones were 150 °C for the quadrupole and 230 °C for the source. Mass spectrometer parameters were electron impact (EI), electron energy set to 70 eV, with acquisition range m/z 33–280. The instrument was tuned daily and analysis of column blanks did not show any contaminating compounds. Analysis of blank trip fiber (an unloaded SPME fiber taken to the site and back, stored with fibers to be analyzed) at the end of each sampling run did not demonstrate contaminating compounds. VOCs were identified tentatively using the Automatic Mass Spectral Deconvolution and Identification System (AMDIS) (National Institute of Standards and Technology, Gaithersburg, MD) and six specialty mass spectral libraries provided derived from the NIST05/EPA/NIH mass spectral database. Known retention times of standards previously analyzed on this system were used for identification. Chemical standards available in house were analyzed to match retention times and mass spectra of unknown compounds. Select reference standards were used for identification, purchased from Sigma-Aldrich (St. Louis, MO, USA). These standards are indicated with ‘+’ in Table 3, Table 4, Table 5. Each sample (as outlined in Section 1.5) was collected on a single SPME fiber, each fiber sample was analyzed by one panelist. The same panelist analyzed all samples with volatiles from each drug and surrogate scent formulation.
