2019 ANNUAL
MEETING
FOCUS ON GASTROINTESTINAL PATHOLOGY
FRIDAY HANDOUTS
1
Update on e-Cigarettes
Drew A. MacGregor, MD, FCCP
Departments of Anesthesiology & Medicine
Wake Forest University School of Medicine
E-cigs: is the smoke clearing?
Disclosures
No financial disclosures at all
Personal: both parents smoked like chimneysMother until she died
Father into mid 60s
Huge exposure to second hand smoke
2
Objectives
Review the mechanics of e-cigs & vapes
Potential benefits of e-cigs
Considerable new data of Risks of e-cigs
Review FDA regulations
Where to go from here
So what are e-cigs & vapes?
History
Cigarettes came to be around 1865Washington Duke in Raleigh rolled and sold to
soldiers at the end of the civil war
First cigarette making machine 1881Could make 120,000 per day !
Tobaccoville, NC factory (Reynolds)Produces 350 Million cigarettes per day
3
MAY I ASSUME….
Tobacco-based cigarettes kill peopleNicotine is just one drug
>20,000 toxins formed by burning tobacco
Over 400,000 people die each year in America due to direct toxic effects from cigarettes
No FDA regulation
Tobacco products largely exempt from any regulation, except in those rare circumstances where manufacturers made explicit health claims
June 22, 2009 – Obama signed into law the “Family Smoking Prevention and Tobacco Control Act” allowing the FDA to regulate manufacturing, marketing and sales
What if we don’t use tobacco?
Water-based flavorings
Superheated vapor
Just Steam instead of smoke
Gotta be healthier right??
Electronic Nicotine Delivery SystemsENDS
4
“Not Appealing to Minors”
E-cigs and vapes ARE marketed to kidsAnd that results in SALES !
MAY I ASSUME….
5
6
A researcher, paid predominately by e-cig and vaping manufacturers, might present misleading or incomplete information?
MAY I ASSUME….
The Fight is On
7
Interesting tidbit
First concept patent by Gilbert in 1963Failed because smoking tobacco was considered
“safe” and more “enjoyable”
E-cig invented in 2003 by Hon Lik – a Beijing pharmacist and 3 ppd smokerFather died of lung cancer
What are PG and VG? In simple terms, PG and VG are the odourless liquids
that are combined with flavour and nicotine to create e-juice. They produce vapour when heated, which allow them to be inhaled. The two fluids have a different consistency to each other, and also have a slightly different taste. They have distinct mouth and throat sensations when vaped. Most modern e-liquid uses a combination of the two fluids, though the ratio can vary dramatically. Some vaping set-ups can only work with a certain level of PG and VG. Choosing the wrong PG/VG ratio can put first-timers off so be careful to choose the right level for your equipment.
Interesting facts….
Nicotine vaporizes at about 290C
Coils in e-cigs & vapes reach 500-800CLots of science:“juice” cooling of coil
Inflow air temp and rate
“dry residue” on coilsTry to minimize
Vehicle for the nicotine “e-juice”Propylene glycol (PG)
Vegetable glycerine (VG)
8
How much nicotine?
Tobacco cigarette puff: 1.54 to 2.60 mg
E-cig puff: 0.5 to 15.4 mg
Salt Lake County Health Dept
Tested amount of nicotine in 153 vape juicesAll from local vape / tobacco shops
Content of Nicotine varied:88% less than listed on label
840% more than listed on label
61% varied by more than 10% of label
Other studies creating regulation that will require testing of “Harmful and Potentially Harmful Constituents” - HPHCs
Are We Ready?
9
In this unregulated, exponentially expanding growth industry, we cannot be certain of what is contained in the e-cigs and vapesAnd, what happens when we burn these
chemicals at very high temperatures
And, what the short and long-term effects of these chemical might be
MAY I ASSUME….
E-cigs might be good
Claim by manufacturer: “e-cigs are between 100 and 1,000 times less dangerous”WHO demands recant – no evidence to support
3,500 users questioned (online questionnaire)79% of people who had quit tobacco cigs felt
they would relapse without e-cigs
Another email study 31% were tobacco free at 6 months
66% reported fewer daily tobacco cigarettes
(n=216)
2009
Lawsuit filed fought FDA’s authority to claim that ENDS meet the definition of a combination drug-device product under the Federal Food, Drug and Cosmetic Act.
FDA’s Division of Pharmaceutical AnalysisDetected diethylene glycol and carcinogens,
including nitrosamines in e-cigs.
July 22, 2009 ENDS regulation begins
10
Comparison to Hook You
Toxic Organic Compounds
Just the First Layer
Are We Learning?
11
Conclusion: Because of the associations between diacetyland bronchiolitis obliterans and other severe respiratory
diseases observed in workers, urgent action is recommended to further evaluate this potentially widespread exposure via flavored e-cigarettes
Finally (2016), the FDA Enters
But what does the FDA do?
Main focus is to prevent e-cigs in kids18 year old age limit initiated
Gives manufacturers 2 years to submit tobacco product applicationAnd the FDA has 1 year to review
The FDA is “exploring (if e-cigs are safer than tobacco cigarettes) with respect to tobacco regulation”
12
What the FDA has NOT DONE
Found evidence that e-cigs help you quit
Found evidence that e-cigs are safer
Determined if regulation will decrease use by those under age 18
Created any list of the potentially toxic compoundsIn the juice itself
Produced by heating the juice
Where to go from here
Wide open researchUnlimited chemicals and “additives”
Toxicity studies ongoing
Variables are almost unlimitedTemp
Solutions
Solvents
Residues
They probably are “SAFER”
Nitrosamines and heavy metals lower0.02 – 10% as high as in tobacco cigarettes
Glycols and other solventsSlightly higher than patches and other NDSs
Known toxicity with ingestion, but don’t know about inhalation toxicity
DiacetylIn 51 of nearly 7,000 flavorings tested
Associated with “popcorn lung”
13
Public Health England 2015
Encourages medical licensing as nicotine replacement therapy, stating, “vaping is 95% safer than smoking” and “can help people to quit smoking and reducing their cigarette consumption, even among those not intending to quit and rejecting other support”
Conclusions: No Doubts
No doubt e-cigs are safer than tobacco
No doubt e-cigs are under-regulatedAmount of nicotine
Toxins in juices
Ability to manipulate juices
Purity of components
Electrical components (batteries/chargers)
No doubt e-cigs are marketed to kids
Conclusions: Little Doubt
Starting e-cigs increases rate of smokingEspecially with kids
Vapes/e-cigs create carcinogenic compounds and have inadequately defined risks
Using e-cigs decreases use of tobacco
Using e-cigs can help people quit smoking
14
Conclusions: Unknown
Long-term effects of components:Nicotine
Metals
HPHCsFlavorings
Vegetable glycerin, Propylene glycol
Risks of vapes & e-cigs vs not using at all
Benefits of vapes & e-cigs over cigarettesActual changes in long term consequences???
October 2010Actress Katherine Heigl is arguably the most responsible for bringing vaping into the public eye by openly vaping on live television during an interview with David Letterman. She claims the vape has really helped her get off of cigarettes.

• AS THE DOGS SNIFFED THE LUGGAGE AND THE BUS, THE AGENTS “WENT THROUGH EVERY
LITTLE THING,” ETHERIDGE RECALLS. EVENTUALLY, ONE DOG POKED ITS NOSE INTO HER BAG.
“I HAD SOME CANNABIS OIL, ACTUALLY A VAPE PEN, IN MY TOILETRY CASE AND THEY
FOUND IT. THEY DIDN’T GET MUCH, IT WAS A SMALL AMOUNT.”
Flavored Water, Flavored nicotine, CBD OIL, “CBD OIL” (A.K.A Synthetic Cannabinods), THC OILs (More popular than we think!)
Other Substances…….Alcohol, Vitamins, Illicit drugs……FENTANYL!!9

VAPING SHOPS: GREENSBORO, NC
10
IS NON-NICOTINE E-LIQUID JUST “WATER VAPOR”?
• NO!
• NICOTINE FREE E-LIQUID EXISTS
• BUT…….
• CONTAINS CARBONYLS, VOCS, AND METALS
AND OVERALL HAVE FEWER CHEMICALS THAN CONVENTIONAL CIGARETTES.
• HOWEVER…….
• THREE OF THE FLAVORING CHEMICALS — CINNAMALDEHYDE, O-VANILLIN AND PENTANEDIONE — ALL CAUSED CYTOTOXICITY OR CELL DEATH.
• IT'S YET TO BE DECIDED IF VAPING IS SAFE, OR IF CERTAIN FLAVORS ARE DEFINITELY MORE DANGEROUS THAN OTHERS. BUT YOU SHOULD STILL PROCEED WITH CAUTION.
• CONCENTRATED DOSES OF CANNABIS MADE BY EXTRACTING CHEMICALS FROM THE PLANT, USING SOLVENTS LIKE BUTANE TO HEAT IT UP. YOU ARE LEFT WITH A WAXY, HONEY-LOOKING PASTE THAT YOU PUT INTO AN E-CIGARETTE, WHICH THEN PRODUCES SMOKE THAT YOU INHALE.
• DAB DOSES ARE EXTREMELY HIGH, BETWEEN 40% AND 80% THC.
THIS IS DEFINITELY NOT THE ROUTE TO GO FOR A FIRST TIME USER!!!
• DABS, ALSO KNOWN AS BUTANE HASH OIL (BHO) — WHICH ARE SOMETIMES CALLED "BUDDER," "HONEYCOMB" OR "EARWAX"
• DUE TO THE USE OF BUTANE IN THE CREATION OF THE DAB WHICH IS WELL DOCUMENTED AS OFTEN CAUSING EXPLOSIONS, THERE IS A REAL RISK HERE OF HARMING YOURSELF.
• HEALTH OFFICIALS ARE INVESTIGATING MORE THAN 30 REPORTS SINCE DECEMBER OF ER PATIENTS WITH SERIOUS SYMPTOMS INCLUDING ALTERED MENTAL STATES, HALLUCINATIONS, SEIZURES, LOSS OF CONSCIOUSNESS AND RAPID HEARTBEATS.
• “PEOPLE SHOULD BE AWARE THAT PRODUCTS LABELED AS CBD OIL MIGHT CONTAIN OTHER SUBSTANCES,” SAID STATE HEALTH DIRECTOR BETSEY TILSON, MD, MPH. “THE SYMPTOMS WE ARE SEEING THAT RESULT IN THESE EMERGENCY DEPARTMENT VISITS ARE NOT TYPICAL FOR CBD OIL USE.”
• NO DEATHS HAVE BEEN REPORTED, AND HEALTH OFFICIALS HAVE NOT LINKED A SPECIFIC BRAND OR SOURCE WITH THE ER VISITS.
• SIMILAR CBD OIL-RELATED SYMPTOMS HAVE BEEN REPORTED AT MEDICAL FACILITIES AT FORT BRAGG AND CAMP LEJEUNE, WHERE MILITARY HEALTH AUTHORITIES HAVE ALSO RAISED CONCERNS.
Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide.
28
• NOT GENERALLY ASSOCIATED WITH VAPING, BUT IT IS CONNECTED TO SYNTHETIC
CANNABINOIDS
• THE NC OCME TOXICOLOGY LABORATORY HAS A QUALITATIVE METHOD FOR THE
DETERMINATION OF BRODIFACOUM, BROMADIOLONE, DIFENACOUM, AND WARFARIN.
• AT THIS TIME, ONLY CASES CONSISTENT WITH COAGULOPATHY SHOULD BE
• THIS STUDY CHARACTERIZED COMMERCIALLY AVAILABLE E-LIQUIDS WITH NO ADVERTISED CONTENT.
• DESIGNER DRUGS SUCH AS MDMB-FUBINACA CAN BE FOUND IN COMMERCIALLY AVAILABLE ELECTRONIC CIGARETTE PRODUCTS.
• THIS DRUG WAS DEMONSTRATED TO AEROSOLIZE AND, THEREFORE, HAS THE POTENTIAL FOR RESPIRATORY DELIVERY.

RECENT 5F-ADB DETECTION IN MULTIPLE U.S. MILITARY SPECIMENS BY THE DOD NEW AND EMERGING DRUGS SURVEILLANCE PROGRAM
• RELATED TO THE PRODUCT BLACK MAGIC SMOKE
• THE SPECIAL FORENSIC TOXICOLOGY DRUG TESTING LABORATORY
DETECTED 28 URINE SPECIMENS THAT CONTAINED 5F-ADB METABOLITE
• WITH A 2.8% PREVALENCE RATE FOR A SPECIFIC LOCATION. NO
OTHER SYNTHETIC CANNABINOIDS WERE PRESENT
SOFT Meeting 2018 MN S50 by Lynn M. Wagner AFME, Dover AFB, DE
31
5F-ADB VS. THC
• ‘super-strength’ synthetic cannabinoids
• K2, Spice, and similar drugs are often referred to as fake marijuana, which can entice people to try it. But what people don’t realize is that these synthetic products contain chemicals that are much more potent than THC
• 5F-AMB and 5F-ADB are 90 and 300 times, respectively, more potent than THC as full agonists for the human CB1 receptor
• Cases present with psychomotor agitation, confusion, anxiety and psychosis.
• FROM A PUBLIC HEALTH PERSPECTIVE, CONCERNS OF LACK OF DATA ON RISKS RELATED TO VAPING RECREATIONAL DRUGS WARRANT ATTENTION
• A CULTURE OF VAPING IS EMERGING THAT INCLUDES THE PERCEIVED POSITIVE ATTRIBUTES OF VAPING CANNABIS AND THE MARKETING OF VAPING DEVICES NOT JUST FOR NICOTINE USE.
• THIS NOVEL CULTURE COULD INCREASE THE PREVALENCE OF USE; DECREASE THE AGE OFONSET OF USE AND LEAD TO MORE PROBLEMATIC USE OF CANNABIS AND OTHER RECREATIONAL DRUGS VIA VAPING DEVICES.
VIALS OF E-LIQUIDS AND/OR MYSTERIOUS AROMAE-CIGARETTES OFTEN DON'T SMELL BAD; HOWEVER, MOST E-LIQUIDS HAVE FLAVORS IN THEM THAT USUALLY SMELL LIKE CANDY, MINT, VANILLA, FRUIT, ETC.
UNFAMILIAR HANDHELD GADGETSE-CIGARETTES COME IN VARIOUS SHAPES. THE MOST COMMON ONES RESEMBLE A PEN. IF YOU COME ACROSS A PEN THAT ISN'T A PEN OR OTHER UNFAMILIAR GADGET, BE AWARE THAT IT COULD BE A VAPORIZER. LOOK FOR HOLES ON EACH END.
BATTERIES AND CHARGERSVAPERS NEED TO CHARGE THEIR VAPORIZERS ON A REGULAR BASIS. WHILE SOME E-CIGS CAN BE CHARGED WITH A USB CABLE, MOST OF THE POWERFUL E-CIGS LIKE BOX MODS SUPPORT 18650 BATTERIES. IF YOU SEE UNFAMILIAR BATTERIES, TAKE A LOOK AROUND AND YOU MIGHT FIND A VAPING DEVICE.
METALLIC WIRES AND COTTON WICKSIF YOU FIND ORGANIC COTTON, EMPTY PLASTIC VIALS OR THIN METALLIC COILS, THIS IS YET ANOTHER RED FLAG.
DISCARDED ATOMIZERSTHE ATOMIZERS ARE A VITAL PART OF E-CIGS AS THEY TURN E-JUICE INTO VAPOR. HOWEVER, AFTER A WHILE USUALLY BURN OUT. IF YOU COME ACROSS A DISCARDED ATOMIZER IN THE TRASH CAN, IT'S A PRETTY CLEAR INDICATION OF VAPING.

NICOTINE HISTORY
• FOR CENTURIES, GARDENERS HAVE USED HOME-MADE MIXTURES OF TOBACCO AND
WATER AS A NATURAL PESTICIDE TO KILL INSECT PESTS
• THE SMOKING OF PIPES AND CIGARS SPREAD QUICKLY THROUGHOUT THE 1600S.
• IN 1828, WILHELM HEINRICH POSSELT, A DOCTOR, AND KARL LUDWIG REINMANN, A
CHEMIST, BOTH FROM GERMANY, FIRST ISOLATED NICOTINE FROM THE TOBACCO
PLANT AND IDENTIFIED IT AS A POISON.
• NICOTINE IS ISOLATED FROM THE TOBACCO PLANT NICOTIANA TABACUM AND
SUSTAINS TOBACCO ADDITION
• THE TOBACCO INDUSTRY EXPLODED IN 1880 WHEN A MACHINE WAS FIRST
Nicotiana tabacum comes from the nightshade family
46
NICOTINE ADME
• NICOTINE CAN BE RAPIDLY ABSORBED THROUGH THE SKIN, ALVEOLI, OR OROPHARYNGEAL MUCOSA,
AS WELL AS THROUGH THE GASTROINTESTINAL MUCOSA AFTER INHALATION, INGESTION, OR DERMAL
CONTACT
• UPON ENTERING THE ARTERIAL CIRCULATION, NICOTINE QUICKLY MOVES TO THE BRAIN AND IS
SUBSEQUENTLY TRANSFORMED INTO TO A NUMBER OF METABOLITES.
• QUANTITATIVELY, THE MOST IMPORTANT METABOLITE OF NICOTINE IS COTININE. IN HUMANS,
ABOUT 70–80% OF NICOTINE IS CONVERTED TO COTININE.
NC OCME TOX CAN DETECT BOTH NICOTINE AND COTININE IN SCREENING METHODS47
NICOTINE TOXICITY
• LOW NICOTINE DOSES STIMULATE THE NEURAL AND CARDIOVASCULAR SYSTEMS
• AWAKENING EFFECT WITH INCREASED HEART RATE AND BLOOD PRESSURE
• HIGH DOSES SUPPRESS THE VITAL SYSTEMS
• BURNING SENSATION IN THE MOUTH AND THROAT, NAUSEA, VOMITING, ABDOMINAL PAIN,
HEADACHE, CONFUSION, DIZZINESS, WEAKNESS, MIOSIS, URINATION AND DEFECATION.
• INGESTION OF HIGHER DOSES LEADS TO ARRHYTHMIAS, BRADYCARDIA, CONVULSIONS,
COMA, RESPIRATORY FAILURE, RAPID PROGRESSION TO HYPOTENSION, AND DEATH
• A LETHAL DOSE OF NICOTINE HAS BEEN ESTIMATED TO BE AS LESS AS 40MG IN ADULTS AND 1
MG/KG IN CHILDREN. HOWEVER, IT IS RECOMMENDED THAT CHILDREN WHO HAVE INGESTED
0.2 MG/KG OR MORE OF NICOTINE BE SEEN BY A PROFESSIONAL48
17
• ELI JAMES "EJ" HOTALING, WHO WOULD HAVE TURNED 2 ON MAY 17, IS THE FIRST CHILD IN THE COUNTRY TO DIE FROM ACCIDENTALLY SWALLOWING THE TOXIC INGREDIENT IN ELECTRONIC CIGARETTES, ACCORDING TO THE AMERICAN ACADEMY OF PEDIATRICS.
• UNCAPPED BOTTLE CONTAINING A NICOTINE SOLUTION ON A LOW TABLE IN THE DINING ROOM
• IT WAS LABELLED HEARTLAND VAPES, 100 MILLIGRAMS, POLICE SAID. THE COMPANY, BASED OUT OF OKLAHOMA CITY, IS A DISTRIBUTOR AND MANUFACTURER OFELIQUIDS AND INGREDIENTS. ON THE COMPANY'S WEBSITE, CHILDPROOF CAPS FOR BROWN, GLASS BOTTLES LIKE THE ONE DESCRIBED BY POLICE ARE AVAILABLE FOR SALE SEPARATELY FROM THE INGREDIENTS AND CONTAINERS.
• PARTIALLY INGESTED BOTTLE OF WHISKEY, 2 EMPTY 15ML VIALS OF CONCENTRATED NICOTINE (100 MG/ML, ALL PRESCRIPTION MEDS HAD APPROPRIATE PILL COUNTS
• BP 74/53 PULSE 106 BPM, RESPIRATION 14 BREATHS/MINUTE, PUPILS FIXED AND DILATED
• MYOCLONIC JERKING, ABSENCE OF CORNEAL, GAG, AND COUGH REFLEXES
• TOX: PLASMA NICOTINE AND COTININE > 1,000 NG/ML
• E-LIQUID BOTTLES WERE NOT TESTED
• DIED 3 DAYS POST-INGESTION
50
• 32-YEAR-OLD MALE ADMITTED TO THE HOSPITAL FOLLOWING CARDIAC ARREST
• INGESTED NICOTINE-CONTAINING E-LIQUID WHILE UNDER THE INFLUENCE OF ALCOHOL.
• HE WAS DESCRIBED AS AGITATED, AND COLLAPSED WITHIN 1 H OF INGESTION OF THE NICOTINE LIQUID.
• HE WAS SHOWN TO HAVE SUFFERED BRAIN HYPOXIA, ATTRIBUTED TO PROLONGED CARDIOPULMONARY RESUSCITATION.
• DRANK APPROXIMATELY 20ML FROM A BOTTLE CONTAINING 72MG/ML NICOTINE LIQUID, LEADING TO A TOTAL INGESTION OF 1440 MG
• A SERUM SAMPLE TAKEN 24 H AFTER COLLAPSE CONTAINED NICOTINE AT A CONCENTRATION OF 1600 NG/ML OF NICOTINE.
51
18
• NO REGULATIONS REGARDING CHILDPROOF BOTTLING AND PACKAGING OR WARNING SIGNS ON LIQUID NICOTINE PRODUCTS
• PARENTS OF CHILD PROVIDED 5ML OF LIQUID NICOTINE MISTAKING IT FOR COLD MEDICINE (CONCENTRATION: 10 MG/ML)
• WHEN THE EMERGENCY MEDICAL TECHNICIANS ARRIVED, SHE WAS FOUND TO HAVE PULSELESS ELECTRICAL ACTIVITY. SPONTANEOUS CIRCULATION WAS RESTORED AFTER APPROXIMATELY 40 MINUTES OF CARDIOPULMONARY RESUSCITATION.
• THE COTININE LEVEL IN HER URINE WAS 1,716 NG/ML.
• DESPITE INTENSIVE SUPPORTIVE CARE, SEVERE ANOXIC BRAIN INJURY WAS FOUND ON COMPUTED TOMOGRAPHY AND THE CHILD ULTIMATELY DIED.
• THIS FATALITY HIGHLIGHTS THE NEED FOR PUBLIC HEALTH EFFORTS TO MINIMIZE SUCH ACCIDENTS.52
PUBLIC HEALTH RISK OR BENEFIT?
• "WE ARE FORTUNATE TO KNOW THE RISKS OF CIGARETTE
SMOKING, BASED ON DECADES OF EPIDEMIOLOGICAL RESEARCH."
WARNER SAID. "IT COULD TAKE YEARS BEFORE WE KNOW THE
FULL HEALTH IMPACT OF VAPING, IF INDEED WE EVER WILL.
The ONLY thing that belongs in your lungs is fresh clean air. Everything else is going to have some negative effects on your lungs and your overall health. Try to get healthy!

Postmortem Forensic Toxicology:An Update on North Carolina’s Opioid Crisis prescription opioids to heroin to fentanyl
Sandra C. Bishop‐Freeman, Ph.D. F‐ABFTNC OCME Deputy Chief Toxicologist
NORTH CAROLINA SOCIETY OF PATHOLOGISTSAnnual Meeting April 12th , 2019
1
Training Outline
1. Office of the Chief Medical Examiner Toxicology Laboratory
2. Dramatic Increases in overdose deaths with heroin and non‐pharmaceutical grade fentanyl
3. Upward trends for stimulants used in combination with illicit opioids
4. Emerging illicit drug combinations: unknown powders, counterfeit mimic tablets
These views are my own and do not reflect the views of the State of North Carolina or any other agency I have worked for in the past!
‐Sandra C. Bishop‐Freeman, Ph.D. F‐ABFT
2
Introduction
• The opioid epidemic explosion is a public health crisis.
• This presentation is filled with facts from the state of North Carolina.
• The certification of opioid deaths has risen significantly in the past few years.
• “Upon the death of any person resulting from violence, poisoning, accident, suicide, or homicide; occurring suddenly when the deceased had been in apparent good health or when unattended by a physician; occurring in a jail, prison, correctional institute, or in police custody; or occurring under any suspicious, unusual or unnatural circumstance, the medical examiner of the county in which the deceased is found shall be notified…” N.C. General Statutes § 130A‐383
5
1. North Carolina Office of the Chief Medical Examiner
• Clinical tests are being used for diagnosis or treatment.▫ Results are only presumptive and qualitative▫ Typically in urine (which is historical in nature)
• Forensic toxicology results are done with the purpose of being used as evidence in legal proceedings, and have a number of stringent requirements because of that purpose.▫ Results are quantitative, screening and confirmation is the gold standard▫ Analysis may need to occur in a variety of specimens within one decedent
2. Dramatic Increases in overdose deaths with heroin and non‐pharmaceutical grade fentanyl
Pain, addiction, trafficking
Pills Heroin Fentanyl Fentalogs
12
5
• Postmortem Interpretation is the most challenging▫ Elevated due to overuse or drug‐drug interactions?
▫ Tolerance will play a huge role
• Medication history is crucial when concentrations are in the upper normal or “in‐between” range▫ The NC Controlled Substances Reporting System (CSRS)
▫ Current prescription info (what, how much, what is left)
• Scene Evidence and recent behavior also could be a deciding factor▫ Other prescription or over‐the‐counter meds?
The Opioid‐dependent Chronic Pain Patient
Example• Oxycodone ER tablets
• 10 mg orally BID
• 60 pills• 10 remaining
• Prescribed 6 days ago• Belonged to decedent
13
Opioid/Benzodiazepine Combo Death
NC OCME data on deaths involving benzodiazepines in combination with opioids
▫ Physicians should check the Controlled Substances Reporting System (CSRS) to verify that patients aren’t taking a prescription opioid before prescribing a benzodiazepine.
NC OCME data on gabapentin‐related deaths
14
1000% in heroin‐related deaths from 2010‐2017
Heroin currently supplemented with fentanyl or fentalogs (fentanyl analogs)
Data set for 2018 is not complete, nowhere back to numbers from early 2010s
Case Study: LC Expanded Screen (LC/ion‐trap MS, Orbitrap)
Presumptive Positive for 6‐MAM, morphine, Oxycodone, Clonazepam Metabolite, Furanylfentanyl,4‐ANPP and below quantitation (BQL) codeine and hydromorphone
NC OCME Certified Toxicology Report

Heroin/Fentanyl/Analogs : MIXTURES
Heroin is often supplemented with varying amounts of fentanyl and/or fentanyl analogues, which explains the increasing numbers of cases positive for both.

Oct‐16 Nov‐16 Jan‐17 Mar‐17 Apr‐17 Jun‐17 Aug‐17
NC OCME Carfentanil
• Carfentanil is considered 100x the potency of fentanyl
• “The side effect of carfentanil is death”
• 52 confirmed and quantitated cases in our OCME Database Oct 2016‐2018
• No cases so far in 2019
10
3. Upward trends for stimulants used in combination with illicit opioids
Recent data from NC OCME
28
Increase in Cocaine found in addition to Fentanyl
• “We’re seeing a dangerous trend of drug dealers and cartels cutting various drugs with fentanyl and increasingly it’s a recipe for death”
• It’s quite possible that this is happening way up stream over the head of dealers
• “Nobody wants to kill off their customer.”
• At NC OCME, 35.6% of fentanyl/analogue‐related deaths also involved cocaine in 2017, compared to 30.6% in 2016.
29
• Meth served as an opioid substitute, provided a synergistic high (i.e., the roller coaster effect), and balanced out the effects of opioids so one could function “normally”
• Helped alleviate opioid withdrawal symptoms, most likely
because of their dual action on dopamine reward systems in the brain
• Methamphetamine‐related deaths increased by 1178.6% from 2010 to 2018 at NC OCME
Synthetic drugs can be altered at a molecular level such that they fall outside current legal definitions of prohibited substances. Sometimes called either “legal highs” or “new psychoactive substances”.
• When all else fails, where I can I find drugs at 3 a.m.?▫ Grocery Stores, Pharmacies, etc.
35
• The recommended daily adult dosage is between 4‐16 mg per day• Users seeking an opioid‐like high from this drug reportedly take it inexcess of 200 mg per dose!!!
• Often seen with diphenhydramine and omeprazole (P‐gp inhibition) • Mid‐2012 to early 2015: 19 cases where loperamide was implicated in COD• Estimate for 2017 is 24 cases• Estimate for 2018 is 22 cases• This is problem is NOT going away!!
13
Synthetic Cannabinoids
• THC and metabolites are not currently analyzed in the NC OCME Tox Lab
• ‘super‐strength’ Select synthetic cannabinoids are recently added to our menu.
• K2, Spice, and similar drugs are often referred to as fake marijuana, which can entice people to try it.
• 5F‐AMB and 5F‐ADB are 90 and 300 times, respectively, more potent than THC as full agonists for the human CB1 receptor
• Patients may present with psychomotor agitation, confusion, anxiety and psychosis.
THC vs. 5F‐ADB
Infant and Toddlers Exposed to Potent Opioids
• “One Pill Can Kill”• Cases were presented at the American Academy of Forensic Sciences meeting• We have had several potent opioid cases in North Carolina including pills such as oxycodone, oxymorphone, prescriptions like methadone and fentanyl patches and illicit drugs such as heroin, fentanyl, and fentalogs including carfentanil
