Drug Decriminalization, Fentanyl, and Fatal Overdoses in Oregon.

Importance: With the implementation of Measure 110 (M110) in 2021, Oregon became the first US state to decriminalize small amounts of any drug for personal use. To date, no analysis of the association of this law with overdose mortality has fully accounted for the introduction of fentanyl-a substance that is known to drive fatal overdose-to Oregon's unregulated drug market. Objective: To evaluate whether the decriminalization of drug possession in Oregon was associated with changes in fatal drug overdose rates after accounting for the rapid spread of fentanyl in Oregon's unregulated drug market. Design, Setting, and Participants: In this cohort study, the association between fatal overdose and enactment of M110 was analyzed using a matrix completion synthetic control method. The control group consisted of the 48 US states and Washington, DC, all of which did not decriminalize drugs. The rapid spread of fentanyl in unregulated drug markets was determined using the state-level percentage of all samples reported to the National Forensic Laboratory Information System that were identified as fentanyl or its analogues. Mortality data were obtained from the Centers for Disease Control and Prevention for January 1, 2008, to December 31, 2022. Data analysis was performed from fall 2023 through spring 2024. Exposures: Measure 110 took effect in Oregon on February 1, 2021. Main Outcomes and Measures: The primary outcome assessed was fatal drug overdose rates per half-year. A changepoint analysis also determined when each state experienced a rapid escalation of fentanyl in its unregulated drug market. Results: In this analysis, rapid spread of fentanyl in Oregon's unregulated drug supply occurred in the first half of 2021, contemporaneous with enactment of M110. A positive crude association was found between drug decriminalization and fatal overdose rate per 100 000 per half year (estimate [SE], 1.83 [0.47]; P < .001). After adjusting for the spread of fentanyl as a confounder, the effect size changed signs (estimate [SE], -0.51 [0.61]; P = .41) and there was no longer an association between decriminalization and overdose mortality in Oregon. Sensitivity analyses were consistent with this result. Conclusions and Relevance: In this cohort study of fatal drug overdose and the spread of fentanyl through Oregon's unregulated drug market, no association between M110 and fatal overdose rates was observed. Future evaluations of the health effects of drug policies should account for changes in the composition of unregulated drug markets.

Trends in Nonfatal Overdose Rates Due to Alcohol and Prescription and Illegal Substances in Colombia, 2010‒2021.

Objectives. To examine drug overdoses in Colombia by type of substance, sex, age, and intent using data from a health surveillance system from 2010 to 2021. Methods. We characterized data by year, type of substance, and sociodemographic variables. We calculated age-adjusted overdose rates by substance type, sex, age groups, and intent. We used Poisson regression models to examine trend differences across sex and age groups. Results. Age-adjusted rates of drug overdoses increased from 8.51 to 40.52 per 100 000 during 2010 to 2021. Men, compared with women, had higher overdose rates for every substance, except for opioids and psychotropics. Drug overdose rates involving cannabis and stimulants increased steadily until 2017 but decreased afterward. Overdose rates involving psychotropic medication increased greatly during 2018 to 2021, mainly because of intentional overdoses in young women. Conclusions. Overdoses involving illegal drugs decreased in recent years in Colombia; however, the continuous increase in intentional psychotropic overdose rates highlights the need for prevention efforts to curb this trend. Health surveillance systems are an important tool that can guide overdose prevention efforts in countries with limited data resources.

Trends in toxicological findings in unintentional opioid or stimulant toxicity deaths in Québec, Canada, 2012-2021: Has Québec entered a new era of drug-related deaths?

INTRODUCTION: We aimed to describe rates and toxicological findings of unintentional opioid and stimulant toxicity deaths, 2012-2021. METHODS: The dataset included accidental deaths determined by the Coroner to be due to opioids or stimulants. We calculated annual crude mortality rates and described combinations of drugs identified in toxicological examinations of these deaths. We described temporal trends in the detection of specific opioids, stimulants, benzodiazepines (including novel benzodiazepines), gabapentinoids and z-drugs in deaths due to opioids and stimulants. RESULTS: Mortality rates increased over time, reaching their peak in 2020 and remaining high in 2021. In deaths due to opioids, there was a decline in the proportion of deaths involving pharmaceutical opioids after 2019, and a corresponding increase in the proportion of deaths with fentanyl detected. Benzodiazepines were often present in deaths due to opioids, with novel benzodiazepines increasing rapidly from 2019 onwards. Cocaine was the most frequently detected drug in deaths due to stimulants, but amphetamine/methamphetamine was detected in around half of all stimulant deaths from 2016 onwards. DISCUSSION AND CONCLUSIONS: Despite availability of a multitude of overdose prevention interventions, mortality rates due to drug toxicity have increased in Québec. Toxicological findings of these deaths suggest concerning shifts in the illicit drug market, with Québec potentially having entered a new era of elevated overdose mortality. Intervention scale-up is essential, but unlikely to be sufficient, to reduce drug-related mortality. Policy reform to address the root causes of drug toxicity deaths, including an unpredictable drug supply, strained health systems and socio-economic precarity, is essential.

Intoxications involving methoxyacetylfentanyl and U-47700: a study of 3 polydrug fatalities.

Novel synthetic opioids (NSOs) represent an emerging group of novel psychoactive substances, acting as agonists at the opioid receptors. NSOs include fentanyl-related compounds, e.g. methoxyacetylfentanyl (MeACF), and non-fentanyl analogs, e.g. "U compounds" including U-47700. Here we present three cases of death involving MeACF and U-47700, with particular reference to preliminary data on pharmacokinetics and tissue distribution.After a complete post-mortem examination, general unknown screenings and analysis of drugs of abuse were performed on postmortem samples by immunoassays, gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. To quantify the analytes of interest in post-mortem blood and tissues, the standard addition method was used. A toxicological significance score (TSS), weighing the role of the NSO in each death case, was assigned.Case 1 died at the hospital after consumption of U-47700, methadone (serum levels: 2,600 ng/ml and 37 ng/ml), tilidine and benzodiazepines. In case 2, U-47700 (204 ng/ml) together with methadone (290 ng/ml), flubromazepam (480 ng/ml) and diazepam (300 ng/ml) were detected in peripheral blood. In case 3, methoxyacetylfentanyl (266 ng/ml), furanylfentanyl (4.3 ng/ml) 4-ANPP (15 ng/ml) and alprazolam (69 ng/ml) were quantified in femoral blood. In all cases, the NSO likely contributed to the death (TSS = 3).NSOs appear to be often consumed in the setting of polydrug intoxications, especially in combination with other opioids and benzodiazepines, which often exert synergistic effects. The standard addition method remains the most reliable in post-mortem analysis and toxicological results should always be evaluated together with circumstantial and autopsy data.

County-level industrial composition of the labor force and drug overdose mortality rates in the United States in 2018-2021.

BACKGROUND: Drug mortality risks vary among industries, creating distinctive geographic patterns across US counties. However, less is known about how local labor market structure relates to drug overdose mortality amid the synthetic opioid era in the United States. This study investigates the relationship between industry-specific job composition and drug overdose mortality at the county level while exploring how fentanyl's presence in illicit drug supplies may moderate the relationship. METHODS: Data were derived from the National Center for Health Statistics' Multiple Cause of Death files for the rates of drug overdose mortality of any intent, linked with four other sources on industry-specific job shares, drug supply, and county-level sociodemographic characteristics and opioid prescribing rates from the US Census Bureau, the CDC, and the Drug Enforcement Administration. Negative binomial regression models were employed to examine associations between county industry-specific job composition and drug overdose mortality, with tests for moderating effects of state-level fentanyl seizure rates. RESULTS: Our models indicate negative associations between job shares of manufacturing, retail trade, and educational services industries and drug overdose mortality. Positive associations were found for arts/entertainment/recreation and public administration. State-level fentanyl seizure rates had moderating effects on administrative/support/waste management/remediation (A/S/WM/R) and educational services. CONCLUSION: Counties with a higher concentration of arts/entertainment/recreation and public administration jobs need targeted efforts to mitigate drug-related overdose risks. Additionally, areas with higher concentrations of A/S/WM/R service jobs, particularly where fentanyl seizure rates are higher, may require proactive harm reduction strategies for reducing overdose risks.

An ecological study of the correlation between COVID-19 support payments and overdose events in British Columbia, Canada.

BACKGROUND: Pandemic income support payments have been speculatively linked to an increased incidence of illicit drug poisoning (overdose). However, existing research is limited. METHODS: Collating Canadian Emergency Response Benefit (CERB) payment data with data on paramedic attended overdose and illicit drug toxicity deaths for the province of British Columbia at the Local Health Area (LHA) level, we conducted a correlation analysis to compare overdose rates before, during and after active CERB disbursement. RESULTS: There were 20,014,270 CERB-entitled weeks identified among residents of British Columbia for the duration of the pandemic response program. Approximately 52 % of all CERB entitled weeks in the study were among females and approximately 48 % were among males. Paramedic-attended overdoses increased uniformly across the pre-CERB, CERB and post-CERB periods, while illicit drug toxicity deaths sharply increased and then remained high over the period of the study. Correlation analyses between overdose and CERB-entitled weeks approached zero for both paramedic-attended overdoses and illicit drug toxicity deaths. CONCLUSIONS: These findings suggest that attributing the pandemic increase in overdose to income support payments is unfounded. Sustained levels of unacceptably high non-fatal and fatal drug poisonings that further increased at the start of the pandemic are reflective of complex pre-existing and pandemic-driven changes to overdose risk.

The impact of an unsanctioned compassion club on non-fatal overdose.

OBJECTIVES: In 2022, the Drug User Liberation Front opened an unsanctioned compassion club in Vancouver where members could purchase illicit drugs that had been rigorously tested to ensure quality and a lack of potentially fatal contaminants. We sought to evaluate the impact of access to this novel safer supply intervention on non-fatal overdose. METHODS: Data were obtained from 47 club members via surveys completed at 3-month intervals between August 2022 and October 2023. We conducted multivariable generalized estimating equations (GEE) analyses to examine the association between club enrolment and the outcomes of: (1) any non-fatal overdose; and (2) any non-fatal overdose involving naloxone administration. RESULTS: The final sample, including 47 study participants, contributed a total of 225 observations and 44.4 person-years of follow-up during the study, and a median follow-up duration of 12.2 months (quartile 1 - 3: 10.4 - 14.7) per participant. In multivariable GEE analyses, enrolment in the compassion club was associated with reduced likelihood of non-fatal overdose (Adjusted Odds Ratio [AOR] = 0.51, 95% Confidence Interval (CI): 0.26 - 0.99) and non-fatal overdose involving naloxone administration (AOR = 0.37, 95% CI: 0.16 - 0.84) after adjusting for potential confounders. DISCUSSION: In this study, enrolment in an unsanctioned compassion club was found to be associated with reductions in any type of non-fatal overdose and non-fatal overdose involving naloxone administration. These findings highlight the need for ongoing research on safer supply interventions, as well as the potential of non-medicalized compassion clubs to complement existing safer supply programming and reduce overdose events.

A Series of 8 Illicit Fentanyl Intoxication Deaths in Infants and Toddlers.

ABSTRACT: We report 8 children younger than 2 years who died from acute illicit fentanyl intoxications in Connecticut between 2020 and 2022.The Connecticut Office of the Chief Medical Examiner (CT OCME) investigates all unexpected, violent, and suspicious deaths in Connecticut. The CT OCME's electronic database was searched for fentanyl deaths by age. All underwent autopsies and toxicology testing.The ages ranged from 28 days to 2 years (mean age, 12 months). The causes of death involved acute fentanyl intoxications with 1 having xylazine, 1 having para-fluorofentanyl, and 1 having cocaine and morphine. All the manners of death were certified as homicide. The postmortem fentanyl blood concentrations ranged from 0.40 to 46 ng/mL. Most of the children were found unresponsive after being put to sleep. Three were co-sleeping with adults (2 in bed; 1 on a recliner). There was a known history of parental/caregiver drug abuse in 7 of 8 of the fatalities.We summarize the key investigative, autopsy, and toxicological findings. As illicit fentanyl use increases, there is a potential for infant exposure and death. The investigation and certification of these deaths and the role of intentional administration versus inadvertent exposure due to caregiver neglect in the context of the certification of the manner of death are described.

Causes of death among people who used illicit opioids in England, 2001-18: a matched cohort study.

BACKGROUND: In many countries, the average age of people who use illicit opioids, such as heroin, is increasing. This has been suggested to be a reason for increasing numbers of opioid-related deaths seen in surveillance data. We aimed to describe causes of death among people who use illicit opioids in England, how causes of death have changed over time, and how they change with age. METHODS: In this matched cohort study, we studied patients in the Clinical Practice Research Datalink with recorded illicit opioid use (defined as aged 18-64 years, with prescriptions or clinical observations that indicate use of illicit opioids) in England between Jan 1, 2001, and Oct 30, 2018. We also included a comparison group, matched (1:3) for age, sex, and general practice with no records of illicit opioid use before cohort entry. Dates and causes of death were obtained from the UK Office for National Statistics. The cohort exit date was the earliest of date of death or Oct 30, 2018. We described rates of death and calculated cause-specific standardised mortality ratios. We used Poisson regression to estimate associations between age, calendar year, and cause-specific death. FINDINGS: We collected data for 106 789 participants with a history of illicit opioid use, with a median follow-up of 8·7 years (IQR 4·3-13·5), and 320 367 matched controls with a median follow-up of 9·5 years (5·0-14·4). 13 209 (12·4%) of 106 789 participants in the exposed cohort had died, with a standardised mortality ratio of 7·72 (95% CI 7·47-7·97). The most common causes of death were drug poisoning (4375 [33·1%] of 13 209), liver disease (1272 [9·6%]), chronic obstructive pulmonary disease (COPD; 681 [5·2%]), and suicide (645 [4·9%]). Participants with a history of illicit opioid use had higher mortality rates than the comparison group for all causes of death analysed, with highest standardised mortality ratios being seen for viral hepatitis (103·5 [95% CI 61·7-242·6]), HIV (16·7 [9·5-34·9]), and COPD (14·8 [12·6-17·6]). In the exposed cohort, at age 20 years, the rate of fatal drug poisonings was 271 (95% CI 230-313) per 100 000 person-years, accounting for 59·9% of deaths at this age, whereas the mortality rate due to non-communicable diseases was 31 (16-45) per 100 000 person-years, accounting for 6·8% of deaths at this age. Deaths due to non-communicable diseases increased more rapidly with age (1155 [95% CI 880-1431] deaths per 100 000 person-years at age 50 years; accounting for 52·0% of deaths at this age) than did deaths due to drug poisoning (507 (95% CI 452-562) per 100 000 person-years at age 50 years; accounting for 22·8% of deaths at this age). Mirroring national surveillance data, the rate of fatal drug poisonings in the exposed cohort increased from 345 (95% CI 299-391) deaths per 100 000 person-years in 2010-12 to 534 (468-600) per 100 000 person-years in 2016-18; an increase of 55%, a trend that was not explained by ageing of participants. INTERPRETATION: People who use illicit opioids have excess risk of death across all major causes of death we analysed. Our findings suggest that population ageing is unlikely to explain the increasing number of fatal drug poisonings seen in surveillance data, but is associated with many more deaths due to non-communicable diseases.

Trends in and Characteristics of Drug Overdose Deaths Involving Illicitly Manufactured Fentanyls - United States, 2019-2020.

During May 2020-April 2021, the estimated number of drug overdose deaths in the United States exceeded 100,000 over a 12-month period for the first time, with 64.0% of deaths involving synthetic opioids other than methadone (mainly illicitly manufactured fentanyls [IMFs], which include both fentanyl and illicit fentanyl analogs).* Introduced primarily as adulterants in or replacements for white powder heroin east of the Mississippi River (1), IMFs are now widespread in white powder heroin markets, increasingly pressed into counterfeit pills resembling oxycodone, alprazolam, or other prescription drugs, and are expanding into new markets, including in the western United States† (2). This report describes trends in overdose deaths involving IMFs (IMF-involved deaths) during July 2019-December 2020 (29 states and the District of Columbia [DC]), and characteristics of IMF-involved deaths during 2020 (39 states and DC) using data from CDC's State Unintentional Drug Overdose Reporting System (SUDORS). During July 2019-December 2020, IMF-involved deaths increased sharply in midwestern (33.1%), southern (64.7%), and western (93.9%) jurisdictions participating in SUDORS. Approximately four in 10 IMF-involved deaths also involved a stimulant. Highlighting the need for timely overdose response, 56.1% of decedents had no pulse when first responders arrived. Injection drug use was the most frequently reported individual route of drug use (24.5%), but evidence of snorting, smoking, or ingestion, but not injection drug use was found among 27.1% of decedents. Adapting and expanding overdose prevention, harm reduction, and response efforts is urgently needed to address the high potency (3), and various routes of use for IMFs. Enhanced treatment for substance use disorders is also needed to address the increased risk for overdose (4) and treatment complications (5) associated with using IMFs with stimulants.

Impact of co-ingestion of ethanol on the clinical symptomatology and severity of patients attended in the emergency department for recreational drug toxicity.

OBJECTIVE: Investigate whether there are differences in the drugs involved, symptomatology and severity of drug intoxication in patients with co-ingestion of alcohol attended in hospital emergency departments (ED). METHOD: Patients attended in 11 Spanish EDs due to drug intoxication were included. Sociodemographic and clinical characteristics were collected. A combined adverse event of cardiorespiratory arrest, need for intubation, and admission to intensive care or death was considered as the primary indicator of severity. The symptomatology and severity were compared adjusted for age, sex and type of drug based on whether or not ethanol had been co-ingested. RESULTS: 3925 patients (alcohol co-ingestion: 2290, 58.3%) with a mean age of 33 (±11) years were included, and 25% were women. Co-ingestion of alcohol was observed in younger patients, in EDs in areas with high leisure tourism, on holidays and during the early morning hours. It was also more frequent in individuals intoxicated by amphetamine derivatives (66.2%) and cocaine (65.7%), and was more frequently associated with a reduction in consciousness (odds ratio [OR] = 2.13, 95% confidence interval [CI] 1.69-2.67) and agitation/aggressiveness (OR = 1.22, 95% = 1.04-1.43). A combined adverse event was observed in 114 patients (2.9%) with no differences between individuals co-ingesting or not ethanol (3.1% vs. 2.7%; OR = 1.11, 95% CI = 0.74-1.65). CONCLUSION: Co-ingestion of alcohol is more frequent in individuals intoxicated by cocaine and amphetamines and predisposes a greater reduction in the level of consciousness or agitation, although there are no differences in the severity of the episodes of drug intoxication.

Conclusión: Considerando que tanto el consumo como el tráfico de drogas se mantienen como un importante problema de salud pública y que sus consecuencias pueden ser devastadoras, es importante tener conocimiento sobre el tema.

Aim: To present the case of a patient with acute cocaine intoxication in the context of body packing syndrome, taking into consideration its medical-surgical and legal aspects. Materials and Method: A clinical record with anonymity protection was obtained, from a patient who was admitted to the emergency room and who was subsequently operated on and managed at Hospital El Pino in San Bernardo, Chile. Results: Patient underwent a gastrotomy, an enterotomy and a colotomy after being stabilized from a cardiorespiratory arrest in the emergency room. He was transferred to the Intensive Care Unit (ICU) where he evolved unfavorably. Discussion: Body packing is an infrequent clinical entity that, in a few cases, may develop severe complications that require immediate medical-surgical treatment, in addition to notification to authorities. Conclusion: Considering that both drug use and traffick remain as an important public health concern and that as its consequences may be devastating, it is important to have a knowledge on the subject.

Spatiotemporal Analysis of the Association Between Pain Management Clinic Laws and Opioid Prescribing and Overdose Deaths.

Pain management clinic (PMC) laws were enacted by 12 states to promote appropriate opioid prescribing, but their impact is inadequately understood. We analyzed county-level opioid overdose deaths (National Vital Statistics System) and patients filling long-duration (≥30 day) or high-dose (≥90 morphine milligram equivalents per day) opioid prescriptions (IQVIA, Inc.) in the United States in 2010-2018. We fitted Besag-York-Mollié spatiotemporal models to estimate annual relative rates (RRs) of overdose and prevalence ratios (PRs) of high-risk prescribing associated with any PMC law and 3 provisions: payment restrictions, site inspections, and criminal penalties. Laws with criminal penalties were significantly associated with reduced PRs of long-duration and high-dose opioid prescriptions (adjusted PR = 0.82, 95% credible interval (CrI): 0.82, 0.82, and adjusted PR = 0.73, 95% CI: 0.73, 0.74 respectively) and reduced RRs of total and natural/semisynthetic opioid overdoses (adjusted RR = 0.86, 95% CrI: 0.80, 0.92, and adjusted RR = 0.84, and 95% CrI: 0.77, 0.92, respectively). Conversely, PMC laws were associated with increased relative rates of synthetic opioid and heroin overdose deaths, especially criminal penalties (adjusted RR = 1.83, 95% CrI: 1.59, 2.11, and adjusted RR = 2.59, 95% CrI: 2.22, 3.02, respectively). Findings suggest that laws with criminal penalties were associated with intended reductions in high-risk opioid prescribing and some opioid overdoses but raise concerns regarding unintended consequences on heroin/synthetic overdoses.

Recreational ketamine-related deaths notified to the National Programme on Substance Abuse Deaths, England, 1997-2019.

BACKGROUND: Ketamine is a phencyclidine derivative with dissociative anaesthetic properties. Increasing numbers of individuals in England take ketamine recreationally. Information on deaths arising from such use in England is presented. METHODS: Cases were extracted on 31 January 2020 from the National Programme on Substance Abuse Deaths database, based on text searches of the cause of death, coroner's verdict and positive toxicology results for the terms 'ketamine' or 'norketamine'. FINDINGS: During 1997-2005, there were <5 deaths p.a. in which ketamine was implicated. Numbers increased until 2009 (21), plateauing until 2016; thereafter, deaths have risen to about 30 p.a. Decedents' characteristics (N = 283): male 84.1%, mean age 31.2 (SD 10.0) years, employed 56.5%, drug use history 79.6% and living with others 60.3%. Ketamine was detected with other substances in most cases. Main (74.6%) underlying cause of death was accidental poisoning. Ketamine may have impaired judgement in other cases. CONCLUSIONS: Although controlled, recreational ketamine use and related fatalities continue to increase. Consumers need to be more aware of the potentially fatal risks they face.

The rise of illicit fentanyls, stimulants and the fourth wave of the opioid overdose crisis.

PURPOSE OF REVIEW: This review provides an update on recently published literature on the rise of illicit fentanyls, risks for overdose, combinations with other substances, e.g. stimulants, consequences, and treatment. RECENT FINDINGS: Overdose due to illicit synthetic opioids (e.g. fentanyl and fentanyl analogs) continues to rise in the US both preceding and during the COVID-19 pandemic. Fentanyl-related overdose is rising in new geographic areas e.g. the western USA. Stimulant-related overdose is also increasing nationwide driven by methamphetamine and cocaine. Polysubstance use, e.g. the use of a stimulant along with an opioid is driving stimulant-related overdose. Other medical consequences of injection drug use are rising including HIV and hepatitis C infections. Medication approaches to treating opioid use disorder remain the standard of care and there are new promising pharmacological approaches to treating methamphetamine use disorder. SUMMARY: A 'fourth wave' of high mortality involving methamphetamine and cocaine use has been gathering force in the USA. Availability and use of illicit fentanyls are still the major drivers of overdose deaths and the current rise in stimulant-related deaths appears entwined with the ongoing opioid epidemic.

Fentanyl contaminated "M30" pill overdoses in pediatric patients.

BACKGROUND: Fentanyl is a high potency opioid that has become an increasingly large proportion of the illicit drug supply. Fentanyl overdoses and deaths, including in pediatric patients, has concomitantly increased. PURPOSE: To describe two cases of pediatric fentanyl overdoses via "M30" pills illicitly sold as oxycodone. BASIC PROCEDURES: Two cases of pediatric opioid toxicity reportedly from oxycodone are presented in which mass spectrometry was used to confirm fentanyl and not oxycodone exposure. MAIN FINDINGS: Both pediatric patients required naloxone and admission to the intensive care unit following exposure. Both had urine drug screens that did not show the presence of opioids but mass spectrometry testing confirmed fentanyl exposure. CONCLUSIONS: Providers should be aware of these illicit tablets, know not to assume they are pharmaceutical, and consider the risk they pose to pediatric patients through exploratory ingestion or misuse. Further inquiry, including social investigation, should be considered for pediatric patients presenting with reported oxycodone ingestion, especially blue "M30" pills.

Fatal intoxication related to two new arylcyclohexylamine derivatives (2F-DCK and 3-MeO-PCE).

Continuous development and rapid turnover of drug market of new psychoactive substances (NPS) make it difficult to obtain up-to-date analytical methods for efficient detection of intoxication cases with new substances: no analytical data and no previously published concentration values in biological samples are indeed available. In this context, we aim to report the first fatal case involving two newly emerging arylcyclohexylamine derivatives (a group of dissociative ketamine-based substances): 2-fluoro-deschloroketamine (2F-DCK) and 3-methoxyeticyclidine (3-MeO-PCE). A 42-year-old man was found dead at his home with three plastic bags of "research chemicals" powders near him. Comprehensive screenings of drugs and toxic compounds as well as more selective assays (performed using NMR, HS-GC-FID, LC-MS/MS and LC-HRMS methods) allowed (1) to identify the three unknown powders, 2F-DCK, 3-MeO-PCE, and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT, a hallucinogenic tryptamine-related NPS), with purity above 95%, and (2) to determine peripheral blood (1780, 90, and 52 µg/L), urine (6.1, 6.3, and 2.2 mg/L), bile (12, 3.5, and 1.7 mg/L), and vitreous humour (1500, 66 and 155 µg/L) concentrations of 2F-DCK, 3-MeO-PCE and 5-MeO-DMT, respectively. In addition, toxicological results also revealed recent use of cannabis, cocaine, and amphetamine by the victim, and hair analysis draw pathway of addiction (including experiments with various other NPS) for several months before death. This fatality was considered as the consequence of respiratory depression in a poly-drug user due to a "cocktail effect" of concurrent intakes of 2F-DCK (mainly), 3-MeO-PCE, 5-MeO-DMT, amphetamine, and cocaine. In addition, this case report provides analytical data that could support subsequent toxicological result interpretation in forensic cases involving such arylcyclohexylamine derivatives.

Pediatric opioid fatalities: What can we learn for prevention?

The aim of this study was to highlight 19 cases investigated by the North Carolina Office of the Chief Medical Examiner over the last 12 years involving accidental or undetermined manner of death opioid ingestions leading to fatalities in young children. These pediatric ingestions have closely mirrored the opioid epidemic in adults transitioning from prescription medications to illicit drugs including fentanyl and fentanyl analogues. Unlike a typical adult ingestion for purposes of self-harm or pleasure, poisonings in toddlers and infants are usually the result of curiosity, exploration, a decreased sense of danger, or imitation of adult or older sibling behavior. Eleven of the decedents were between the ages of 8 and 24 months. Among the cases were 12 prescription opioid exposure deaths and 7 illicit drug poisonings. A majority of the decedents were found unresponsive in an unkept home and/or in unsafe sleeping spaces with easy access to drugs or drug materials, which stresses the importance of safe pediatric sleeping conditions. After a complete pathological investigation, several of the cases had physical or scene evidence demonstrating that foil, plastic, or paper small enough to be ingested can contain enough potent opioid to cause death. Details from the toxicological investigation are included for each case to provide postmortem whole blood drug concentrations for forensic practitioners. Accidental pediatric poisonings are preventable. Risk reduction through improving awareness and education of the dangers of opioids is a key factor in mitigating these tragedies.
