Sex-specific role of the 5-HT2A receptor in psilocybin-induced extinction of opioid reward.

Nature Communications November 20, 2025 Alaina M Jaster, Thomas M Hadlock, Belle Buzzi et al. 9 citations

Emerging evidence suggests that classical psychedelics may offer therapeutic potential for opioid use disorder (OUD) by alleviating key hallmarks such as altered reward processing and dependence. However, the mechanisms behind these effects remain unclear. Our data demonstrate that a single administration of the psychedelic psilocybin (PSI) reduces conditioned behavior and withdrawal induced by...

Survey of U.S. Residents and Their Usage of Electronic Cigarettes with Drugs Other Than Nicotine.

Journal of Psychoactive Drugs 2024 Alaina K Holt, Alyssa K Rudy, Ashlee N Sawyer et al. 2 citations

Electronic cigarettes (e-cigs), originally intended to be used as cigarette substitutes, have evolved into discreet devices for consuming drugs other than nicotine (DOTNs). Presented are the results of an exploratory survey in which information regarding demographics, e-cig device type, DOTN use, frequency and context of use was collected. The average reported age of respondents was 27.4 years...

Differences across sexes on head-twitch behavior and 5-HT2A receptor signaling in C57BL/6J mice.

Neuroscience Letters September 25, 2022 Alaina M Jaster, Jason Younkin, Travis Cuddy et al. 53 citations

Psychedelics, also known as classical hallucinogens, affect processes related to perception, cognition and sensory processing mostly via the serotonin 5-HT2A receptor (5-HT2AR). This class of psychoactive substances, which includes lysergic acid diethylamide (LSD), psilocybin, mescaline and the substituted amphetamine 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI), is receiving renewed...

Fully automated head-twitch detection system for the study of 5-HT2A receptor pharmacology in vivo

Scientific Reports October 3, 2019 Mario de la Fuente Revenga, Jong M. Shin, Hiba Vohra et al. 57 citations

Abstract Head-twitch behavior (HTR) is the behavioral signature of psychedelic drugs upon stimulation of the serotonin 5-HT 2A receptor (5-HT 2A R) in rodents. Following the previous report of a semi-automated detection of HTR based on the dynamics of mouse’s head movement, here we present a system for the identification of individual HTR events in a fully automated fashion. The validity of...

Identification of Metabolite Biomarkers of the Designer Hallucinogen 25I-NBOMe in Mouse Hepatic Microsomal Preparations and Human Urine Samples Associated with Clinical Intoxication.

Journal of Analytical Toxicology October 1, 2015 Justin L. Poklis, Sara K Dempsey, Kai Liu et al.

'NBOMe' (dimethoxyphenyl-N-[(2-methoxyphenyl)methyl]ethanamine) derivatives are a new class of designer hallucinogenic drugs widely available on the Internet. Currently, 2-(4-iodo-2,5-dimethoxyphenyl)-N-[(2-methoxyphenyl)methyl]ethanamine (25I-NBOMe) is the most popular abused derivative in the USA. There are little published data on the absorption, metabolism and elimination of 25I-NBOMe, or...

Analysis of 25I-NBOMe, 25B-NBOMe, 25C-NBOMe and Other Dimethoxyphenyl-N-[(2-Methoxyphenyl) Methyl]Ethanamine Derivatives on Blotter Paper

Journal of Analytical Toxicology September 16, 2015 Justin L. Poklis, Stephen A. Raso, Kylie N. Alford et al. 93 citations

In recent years, N-methoxybenzyl-methoxyphenylethylamine (NBOMe) derivatives, a class of designer hallucinogenic drugs, have become popular drugs of abuse. These drugs have been the cause of severe intoxications and even deaths. They act as 5-HT2A receptors agonists and have been reported to produce serotonin-like syndrome with bizarre behavior, severe agitation and seizures persisting for as...

Toxicities associated with NBOMe ingestion-a novel class of potent hallucinogens: a review of the literature.

Psychosomatics 2015 Joji Suzuki, Michael A Dekker, Erin S Valenti et al.

A new class of synthetic hallucinogens called NBOMe has emerged as drugs of abuse. Our aim was to conduct a systematic review of published reports of toxicities associated with NBOMe ingestion. We searched PubMed for relevant English-language citations that described adverse effects from analytically confirmed human NBOMe ingestion. Demographic and clinical data were extracted. A total of 10...

Evolution of the NBOMes: 25C- and 25B- Sold as 25I-NBOMe

Journal of Medical Toxicology November 12, 2014 Larissa K. Laskowski, Faesal Elbakoush, Jessica Calvo et al. 39 citations

IntroductionThe NBOMes (N-benzyl-oxy-methyl derivatives of known 2C phenylethylamines) are a new and growing class of potent synthetic stimulants. Case reports provide the bulk of available safety and clinical data for clinicians. We report two cases of NBOMe intoxication with 25C-NBOMe (the first lab-confirmed US case) and 25B-NBOMe, respectively, both confirmed via triple quadrapole mass...

“My Friend Said it was Good LSD”: A Suicide Attempt Following Analytically Confirmed 25I-NBOMe Ingestion

Journal of Psychoactive Drugs October 20, 2014 Joji Suzuki, Justin L. Poklis, Alphonse Poklis 60 citations

A new class of synthetic hallucinogens called NBOMe has emerged, and reports of adverse effects are beginning to appear. We report on a case of a suicide attempt after LSD ingestion which was analytically determined to be 25I-NBOMe instead. Clinicians need to have a high index of suspicion for possible NBOMe ingestion in patients reporting the recent use of LSD or other hallucinogens.

High‐performance liquid chromatography tandem mass spectrometry method for the determination of 2CC‐NBOMe and 25I‐NBOMe in human serum

Biomedical Chromatography December 1, 2013 Justin L. Poklis, Jezelle Charles, Carl E. Wolf et al.

ABSTRACT2CC‐NBOMe {4‐chloro‐2,5‐dimethoxyphenethyl‐N‐[(2‐methoxyphenyl) methyl] ethanamine} and 25I‐NBOMe {2‐(4‐iodo‐2,5‐dimethoxyphenyl)‐N‐[(2‐methoxyphenyl) methyl] ethanamine} are of a class of N‐benzyl phenethylamine derivatives whose synthesis was first reported in the scientific literature in 2011. Recent reports from ‘personal drug experience websites’ and in the popular press indicate...

A case of 25I-NBOMe (25-I) intoxication: a new potent 5-HT2A agonist designer drug

Clinical Toxicology March 1, 2013 S. Rose, Justin L. Poklis, Alphonse Poklis

Context. Abuse of synthetic stimulant compounds resulting in significant toxicity is being increasingly reported by poison centers. Toxicologic assessment is complicated by inconsistent manufacturing processes and limited laboratory testing. We describe a case of self-reported exposure to 25-I (25I-NBOMe), a novel phenethylamine derivative, with subsequent quantification in serum. Case details....
