3 Synthetic Analog Problem DEA Temporary Placement of JWH-018, JWH-073, JWH-200, CP47,497 and CP47,497 C8 homolog, MDPV, Mephedrone, Methylone on Schedule 1 H.R. 1254: Synthetic Drug Control Act of 2011 AK S 17: Classifies certain synthetic cannabinoids as schedule IIA controlled substances. AL H 158, S 207 and S 208: Relates to schedule I controlled substances; provides legislative findings relating to controlled substance analogs; adds cathinone compounds, certain named chemical compounds of synthetic cannabinoids, and controlled substance analogs to the schedule I controlled substances list subject to regulation and penalties in the same manner as other controlled substances. AZ S 1043: Relates to dangerous drugs; relates to definition. 3 AZ H 2388: Adds AM-2201 and JWH-122 to the definition of dangerous drugs and to schedule I. Relates to authority to define the chemical composition of controlled substances included in drug schedules; provides for authority to include chemical variations of those substances as necessary; provides consideration of a substance s potential for abuse, pharmacological effect, current scientific knowledge and the risk to public health; requires written report; exempts the board of pharmacy from rulemaking requirements. CA A 2420: Provides that every person who possesses, under circumstances that do not include possession for sale as proscribed pursuant to existing law, 28.5 grams or less of any synthetic cannabinoid or any synthetic stimulant compound, or any synthetic stimulant derivative is guilty of an infraction punishable by a specified fine. HI S 1305: Adds HU-210, JWH-018, JWH-073 to controlled substances provisions.

17 How does it work?

18 GC-IR System optics 18

19 Polystyrene Calibration Infrared beam NIST Traceable polystyrene film for daily calibration test Acquisition of solid phase transmission spectra through ZnSe disc

20 Disc Track Pointer Infrared beam fixed in position Start Sample 2 RT= 0.0 min End Sample 2 RT= 20.0 min ZnSE Disc rotates counterclockwise Records linear position and rotary position for For every spectra

21 Cryogenic LN2 IR Detector Interferometer PCB Sample deposit ZnSe window M C T ABB Bomem Vacuum chamber 21 Precision Vacuum Backplate Optical path

22 Heated Transfer line

23 GC-IR/MS

24 24 Loading the sample disk

25 Sample collection mechanism DiscovIR VACUUM CHAMBER, (10-4 torr) Resistive Heaters +/-5 o C Disc auto load/unload 25 4 inch diameter ZnSe disc, washable & reusable Holds 50 hours of chromatography in spiral track Auto location, Checks for sample, Post dep. analysis

26 Data Acquisition and Instrument Control software based on Thermo GRAMS 26

27 Chromatogram Trace Spectrum Trace Spectrum Trace 27

28 QA/QC / Performance Qualification Voltage check to ensure detector is working properly Noise check to ensure proper signal/noise ratio NIST traceable polystyrene scan is performed A test mix (amphetamine, phentermine, pseudoephedrine, caffeine, cocaine and alprazolam) enables : GC check (proper separation) IR detector (proper identification)

29 Example of a Daily Test Mix Chromatogram

30 Typical Case Work Sample Preparation Sample preparation Sample can be extracted/prepared as if analyzing via GC/MS MeOH (dilute and shoot type) Basic CHCl3, Basic Hex, Acidic CHCl3 Acidic Hex Normal GC/MS vials can be used no real change of procedure needs to be employed

53 Library search of JWH-15 versus library of 40 cannabinoids results in quality score of 0.97

54 Tryptamines

55 Clandestine Tablets Most clandestine tablets are mixtures Can obtain an infrared spectra for each component With the DB-35 column can separate BZP, TFMPP and MDMA (see figures 4-7) Isomer determination for MDMA, TFMPP and CPP (to name just a few)

58 Why use DiscovIR-GC? Resolve and identify mixed analytes in a single instrument and procedure. GC-FTIR provides two analytical methods in one operation. High resolution solid phase spectra Self-cleaning IR disk. No need to manually clean off old samples. Automatic operation up to 50 hours: Autosampler-compatible. Spectral identification library software. Nanogram sensitivity. Flow splitting: can interface with existing GC MS instrumentation. Real-time or post-run data collection. Allows re-analysis of deposited samples

59 Substances Routinely Analyzed via GCIR system Methamphetamine (includes clan lab, powder and residues) Amphetamine Codeine cough syrup Heroin Morphine (residues from spoons, straws, syringes etc) Cocaine Clandestine tablets Oxycodone (residues from spoons, straws, syringes, etc) Tryptamines and phenethylamines Bath Salts Cannabinoids
