Multiple MDMA (Ecstasy) Overdoses at a Rave Event

Journal of Intensive Care Medicine May 28, 2012 Patil Armenian, Tanya M. Mamantov, Ben Tsutaoka et al. 81 citations

Twelve people who took MDMA at a single rave were hospitalized in the San Francisco Bay area with life-threatening complications including seizures and hyperthermia. Eight needed emergency breathing tubes, and six had dangerously low blood pressure. Most had high potassium levels, acute kidney injury, and muscle breakdown. Two died, four survived with permanent neurological, muscle, or kidney damage, and six recovered without lasting harm. Ten had hyperthermia, with seven reaching extreme temperatures between 40.9°C and 43°C. Cooling took an average of 2.7 hours. Drug analysis of two confiscated capsules showed they contained 82% and 98% pure MDMA, with one capsule holding 270 mg—more than twice a typical dose. The MDMA-induced hyperthermia, worsened by large doses, a warm environment, and physical exertion, was a major cause of death and injury.

Ibogaine Consumption With Seizure-Like Episodes, QTc-Prolongation, and Captured Cardiac Dysrhythmias.

The Journal of emergency medicine October 1, 2019 James Grogan, Roy R Gerona, Jerry W Snow et al. 16 citations

Ibogaine, a psychoactive indole alkaloid used experimentally for opioid addiction and available via Internet suppliers, can cause life-threatening cardiac effects. A 34-year-old woman with heroin and cocaine use disorder ingested 2 g of ibogaine powder, experienced hallucinations and seizure-like episodes, and developed QTc prolongation and torsade de pointes. Qualitative analysis confirmed ibogaine in the ingested material. As more people with opioid use disorder seek ibogaine, emergency physicians need to recognize and treat this dangerous exposure.

Internet-purchased ibogaine toxicity confirmed with serum, urine, and product content levels.

The American journal of emergency medicine July 1, 2015 Charles W O'Connell, Roy R Gerona, Matthew W Friesen et al. 16 citations

Ibogaine, a psychotropic indole alkaloid used in some medical subcultures for its anti-addictive properties, can cause serious health risks including altered mental status, ataxia, gastrointestinal distress, ventricular arrhythmias, and sudden death. A 33-year-old man overdosed on ibogaine while attempting to quit heroin, experiencing altered consciousness, tremor, ataxia, nausea, vomiting, and transient QT interval prolongation, which resolved as the substance cleared. Ibogaine was confirmed in his urine and serum, with a peak serum concentration of 377 ng/mL. Nonlinear elimination kinetics and the presence of its active metabolite noribogaine were also observed. This case provides serial serum concentrations and product-confirmed ibogaine toxicity with transient QT interval prolongation.

The electric Kool-Aid NBOMe test: LC-TOF/MS confirmed 2C-C-NBOMe (25C) intoxication at Burning Man.

The American journal of emergency medicine November 1, 2014 Patil Armenian, Roy R Gerona 15 citations

NBOMe derivatives, which are modified versions of the 2C class of phenethylamines, have recently appeared as designer drugs in the US market. While cases of toxicity from one derivative, 2C-I-NBOMe, have been documented, no reports have yet described the clinical effects of another derivative, 2C-C-NBOMe, leaving its toxicity profile unknown.

Seizures, Systemic Inflammatory Response, and Rhabdomyolysis Associated With Laboratory-Confirmed 2C-I and 25-I Exposure.

Pediatric Emergency Care October 1, 2018 Stephen L Thornton, Sarah Hoehn, Roy R Gerona 6 citations

A 17-year-old male experienced seizures, systemic inflammatory response, and rhabdomyolysis after taking what he thought was LSD, but laboratory testing confirmed exposure to the designer drugs 4-iodo-2,5-dimethoxyphenethylamine (2C-I) and its n-benzyloxymethyl analog (25I-NBOMe). Seizures resolved with midazolam, but he required intubation. His urine drug screen was negative. Creatine kinase peaked at 14,579 U/L, and creatinine at 2.46 mg/dL. He recovered fully with intravenous fluids and was discharged after five days. The 2C drugs and their analogs are potent serotonergic agents associated with severe toxicity including seizures, rhabdomyolysis, and death, and should be considered in cases of drug-induced seizures.

Systemic ketamine toxicity following dermal application of a compounded pain cream.

The American journal of emergency medicine February 1, 2025 Skyler Kessler, Bernard Weigel, Ross Ellison et al. 5 citations

A 61-year-old man with open skin ulcers from pyoderma gangrenosum developed ketamine toxicity after applying a large amount of a compounded analgesic cream containing 10% ketamine, 5% lidocaine, and 5% amitriptyline to his perineal and sacral region. He was brought to the emergency department with agitation, altered mental status, and torsional nystagmus after erratic driving. Urine testing showed a ketamine concentration of 32,300 ng/mL. His symptoms resolved spontaneously within a few hours. This case demonstrates that dermal application of ketamine cream can cause systemic toxicity when skin barrier function is impaired.

Quantitative analysis of recreational psychoactive mushroom gummies in Portland, Oregon

Clinical Toxicology February 20, 2025 Courtney Temple, Matthew S. Correia, Ma Gonzaga et al. 3 citations

An analysis of psychoactive mushroom gummies found that their labeling was generally inaccurate. Products that suggested they contained Amanita muscaria instead contained serotonergic tryptamines, and some falsely claimed to be free of psilocybin.

A Case of 3,4-Dimethoxyamphetamine (3,4-DMA) and 3,4-Methylenedioxymethamphetamine (MDMA) Toxicity with Possible Metabolic Interaction.

Journal of Psychoactive Drugs January 1, 2016 Michael A Darracq, Stephen L Thornton, Alicia B Minns et al. 2 citations

A 19-year-old woman had two seizures and dangerously low sodium after taking "ecstasy" at a rave. Laboratory analysis of her blood and urine showed she had taken both MDMA and 3,4-DMA, and that her body produced very low levels of MDMA's CYP2D6 metabolites, indicating impaired metabolism through that pathway. The case suggests that combining MDMA with 3,4-DMA can lead to severe toxicity, including hyponatremia and seizures. Healthcare providers should be aware that people using illicit drugs may take multiple substances, and that such combinations can cause serious harm.

Beyond Ketamine and Phencyclidine: Analytically Confirmed Use of Multiple Novel Arylcyclohexylamines.

Journal of Psychoactive Drugs January 1, 2017 Stephen L Thornton, David Lisbon, Thomas Lin et al.

A 27-year-old man who snorted powder bought online had high blood pressure, rapid heart rate, dissociation, delayed speech, unsteady gait, and vertical nystagmus. Urine drug screening was positive for phencyclidine and a THC metabolite, but blood analysis detected methoxetamine and 3-methoxy-phencyclidine, not phencyclidine or THC. Methoxetamine concentrations were 279, 205, and 180 ng/mL; 3-methoxy-phencyclidine concentrations were 167, 131, and 90 ng/mL at 0, 2, and 3 hours after arrival. His mental state and blood pressure returned to normal eight hours later. This case adds to limited reports on these novel arylcyclohexylamines and their toxicity.
