Objective: To investigate whether the severity of acute recreation drug toxicity presentations to emergency departments (EDs) in Europe has changed in recent years and to uncover potential sex differences.

Design: We analysed presentations to 36 EDs in 24 European countries relating to acute recreational drug toxicity, with separate analysis for presentations involving lone use of cannabis, cocaine, and heroin. As severity markers, we calculated rates of hospitalization, admission to ICU, intubation, and death by annual quarters between 2014 and 2019.

Article Synopsis
  • Patients using recreational drugs often mix them with ethanol, a CNS depressant, but its impact on acute toxicity is not well understood.
  • A retrospective study analyzed 43,633 emergency department cases involving CNS depressants, finding that nearly 50% co-ingested ethanol.
  • Results showed that co-use increases the severity of symptoms, necessitating more medical treatment and intensive care admissions, particularly in cases involving opioids or GHB/GBL.

Objective: To investigate if clinical features associated with acute cannabis intoxication in patients presenting to Emergency Departments for medical assistance differ according to patient age and sex.

Methods: We analysed presentations in the Euro-DEN Plus dataset from 2014 to 2019 in which cannabis was the only drug involved (except for alcohol), and age, sex and alcohol co-ingestion had been recorded. Age was considered as categorical (five groups; <20, 20-29, 30-39, 40-49 and ≥50 years), and sex as binary variable (male/female).

Aims: Toxicity in paracetamol overdose with opioid co-ingestion is poorly understood. We compared outcomes in both paracetamol-only and paracetamol-opioid overdoses to determine whether toxicity differed significantly between the groups, and to assess the utility of the ratio of measured plasma paracetamol concentration relative to the 4-hour nomogram-adjusted level (APAP /APAP ).

Methods: We conducted a retrospective observational study of all patients (n = 1159) presenting to 2 large UK hospitals between 2005 and 2013 with acute single-dose ingestion paracetamol overdose, with (n = 221) or without (n = 938) opioid co-ingestion.

Objective: Ethanol intake can increase the sedative effects of gamma-hydroxybutyrate/gamma-butyrolactone (GHB/GBL), although the real clinical impact is unknown. We studied the clinical impact of the co-ingestion of ethanol in patients presenting to the Emergency Department (ED) with acute toxicity related to GHB/GBL use.

Method: We performed a secondary analysis of the Euro-DEN Plus Registry (14 countries, 22 EDs) which includes 17,371 consecutive patients presenting to the ED with acute recreational drug toxicity over 39 consecutive months (October 2013 - December 2016).

Tampering with opioid containing medications for use other than their prescribed indication is well documented; however, the published literature has concentrated on stronger, prescription opioids. Less potent opioids, such as codeine, are available without prescription in many European countries in the form of combination analgesic products and these can also be altered, with reports in particular of "cold-water extraction" being a tampering method achievable using household kitchen equipment. We searched a database of patients attending two South London emergency departments for cases of self-reported ingestion of the products of cold-water extraction, with subsequent review of their case notes.

Article Synopsis
  • The study aimed to analyze the clinical profile of GHB (gamma-hydroxybutyrate) and GBL (gammabutyrolactone) intoxication among European patients, focusing on differences between those using these substances alone versus in combination with other drugs.
  • Data were collected over 12 months from Emergency Departments in the Euro-DEN network, including 710 intoxication cases, mostly affecting young males (mean age 31).
  • Key findings revealed that most patients arrived by ambulance during weekends, often combining GHB/GBL with other substances like alcohol and amphetamines, leading to a higher incidence of severe symptoms and longer hospital stays compared to those using GHB/GBL alone.
