Semi-synthetic cannabinoids are a class of new psychoactive substances (NPSs) with structural similarities to the main psychoactive phytocannabinoid Δ9-tetrahydrocannabinol (Δ9-THC) found in Cannabis sativa L. The first semi-synthetic cannabinoids, which were used as legal substitutes for marijuana, were Δ8-tetrahydrocannabinol (Δ8-THC) and hexahydrocannabinol (HHC). Δ8-THC emerged around 2019 on the recreational…
Delta-8 THC is a psychoactive cannabinoid typically synthesized from hemp, with similar intoxicating effects as delta-9 THC. Surging public interest alongside the lack of federal regulation of delta-8 THC has led to an unclear legal landscape and increasing safety concerns. Educating young adults about the dangers of delta-8 THC is imperative. The current study investigated the effects of a brief educational video…
Abstract The use of Δ8-tetrahydrocannabinol (Δ8-THC) has become increasingly prevalent in the United States but its metabolic pathways remain poorly characterized. This study aimed to identify the key enzymes responsible for the 11′-hydroxylation of Δ8-THC, its primary metabolic pathway, and assess the effect of metabolizing enzyme genotype on this activity. The intrinsic clearance of recombinant (r) CYP2C9 was >…
Cannabinoid use and misuse has been rising since 2011, and the development of new cannabinoid derivatives, partially due to the passage of the Farm Bill in 2018, and more relaxed legislation, has complicated testing for this drug class. The impact on child welfare in homes with cannabis substance use remains a concern, so detection of environmental exposure to cannabinoids is hugely beneficial. This article report…
The growing use of e-cigarettes as vehicles for illicit drug delivery has created an urgent challenge for forensic surveillance and public health in East Asia. This study analyzed 496 e-liquid samples seized by law-enforcement agencies in Eastern Taiwan (January-July 2025) using a full-scan GC-MS workflow validated in accordance with ANSI/ASB forensic toxicology standards. Overall, 80.8% of samples (n = 401) teste…
The increased use of cannabis in many parts of the United States and other countries has led to a need for a more comprehensive understanding of cannabis constituents and their potential for drug-drug interactions. Δ8-Tetrahydrocannabinol (Δ8-THC) is a psychoactive cannabinoid that is found at low concentrations in cannabis but is growing in popularity, especially where the use of Δ9-THC is restricted. Although ce…
Background Since the passage of the 2018 US Farm Bill there has been a market for cannabinoid products derived from Cannabis sativa L. that contain < 0.3% delta-9 tetrahydrocannabinol (THC). Understanding the characteristics and motivations of cannabinoid product users is crucial for appropriate regulation of these products. Methods We conducted a cross-sectional survey of 1,523 adults 18 years or older using the…
Delta-8-tetrahydrocannabinol (Δ8-THC) products, made from hemp-derived cannabidiol, have become more widely available since changes in legislation allowed hemp to be excluded from controlled substances. These products are often perceived as a safe, legal, and accessible alternative to marijuana or delta-9-tetrahydrocannabinol. However, scientific research on their effects remains limited. There have been reports o…
Patients with arthritis report using cannabis for pain management, and the major cannabinoid delta-9-tetrahydrocannabinol (Δ9-THC) has anti-inflammatory properties, yet the effects of minor cannabinoids on arthritis are largely unknown. The goal of the present study was to determine the antiarthritic potential of the minor cannabinoid delta-8-tetrahydrocannabinol (Δ8-THC) using the collagen-induced arthritis (CIA)…
Chronic pain conditions affect nearly 20% of the population in the United States. Current medical interventions, such as opioid drugs, are effective at relieving pain but are accompanied by many undesirable side effects. This is one reason increased numbers of chronic pain patients have been turning to Cannabis for pain management. Cannabis contains many bioactive chemical compounds; however, current research look…
Introduction This study investigated exposures involving ∆8-tetrahydrocannabinol (∆8-THC) reported to US poison centers (PCs), including variation among states and regions. It evaluated whether the ∆8-THC exposure rate was lower among states with ∆8-THC regulations and states where cannabis (∆9-THC) use was legal. Methods National Poison Data System data for ∆8-THC exposures in 2021-2022 were analyzed, including c…
This study explores the potential of using large language models to assist content analysis by conducting a case study to identify adverse events (AEs) in social media posts. The case study compares ChatGPT's performance with human annotators' in detecting AEs associated with delta-8-tetrahydrocannabinol, a cannabis-derived product. Using the identical instructions given to human annotators, ChatGPT closely approx…
The diversity of cannabinoid isomers and complexity of Cannabis products pose significant challenges for analytical methodologies. In this study, we developed a method to analyze 14 different cannabinoid isomers in diverse samples within milliseconds by leveraging the unique adduct-forming behavior of silver ions in advanced cyclic ion mobility spectrometry-mass spectrometry. The developed method achieved the sepa…
Cannabis-induced psychosis (CIP) is an increasingly acknowledged psychiatric phenomenon observed in vulnerable patients exposed to cannabis. This brief case report details a male patient in his 20s, who presents to the ED with derealization two days after ingesting a gummy worm containing delta-8-tetrahydrocannabinol (Δ8-THC). Two days post-ED discharge, the patient gradually developed symptoms of religious-themed…
Objective This study aims to describe patterns, sources, and reasons for cannabis use among cancer patients during active treatment (+CDTX) compared to no-use during active treatment (-CDTX). Methods Data are from 385 surveys collected via REDCap during phase I of an ongoing study among adult cancer patients seen at an NCI-designated comprehensive cancer center within the last 5 years of treatment. A harmonized su…
Cannabis sativa is one of the oldest plants utilized by humans for both economic and medical purposes. Although the use of cannabis started millennia ago in the Eastern hemisphere, its use has moved and flourished in the Western nations in more recent centuries. C. sativa is the source of psychoactive cannabinoids that are consumed as recreational drugs worldwide. The C21 aromatic hydrocarbons are restricted in th…
Background The recent exponential increase in legalized medical and recreational cannabis, development of medical cannabis programs, and production of unregulated over-the-counter products (e.g., cannabidiol (CBD) oil, and delta-8-tetrahydrocannabinol (delta-8-THC)), has the potential to create unintended health consequences. The major cannabinoids (delta-9-tetrahydrocannabinol and cannabidiol) are metabolized by…
Background In this review, we summarize current scientific knowledge on psychoactive cannabinoids synthesized from cannabidiol (CBD) and sold in the semi-legal market established in response to the passage of the US Agriculture Improvement Act of 2018, commonly known as the 2018 Farm Bill. The discussion focuses on recent developments that suggest this unregulated market may be fertile ground for a potential healt…
Introduction The association between Δ8-tetrahydrocannabinol (THC) and cardiac dysrhythmia has not been well described in children. Asystole, while consistent with reports of severe bradycardia and apnea in children, is uncommonly described in the current literature. We present the first pediatric case of asystole and apnea following THC ingestion. Case A 7-year-old male presented to the emergency department (ED)…
