Abstract
Background: Mitragynine pseudoindoxyl (MP) is a semi-synthetic kratom metabolite increasingly sold online and over-the-counter, marketed misleadingly as “kratom” or “7-OH,” despite lacking FDA approval and safety data in humans. Methods: This case report describes a 44-year-old male with polysubstance use history who developed [...] Read more.
Background: Mitragynine pseudoindoxyl (MP) is a semi-synthetic kratom metabolite increasingly sold online and over-the-counter, marketed misleadingly as “kratom” or “7-OH,” despite lacking FDA approval and safety data in humans. Methods: This case report describes a 44-year-old male with polysubstance use history who developed opioid withdrawal symptoms after regular MP use (400 mg daily for pain management following neck injury). Vital signs, alcohol and opioid withdrawal scores and clinical outcomes were recorded. Results: The patient presented exhibiting symptoms of moderate opioid withdrawal in the absence of other opioid use. A buprenorphine macro-induction protocol was initiated. Following pre-treatment using chlorpromazine as an anti-emetic and diazepam to treat concomitant alcohol withdrawal, 32 mg buprenorphine were provided (16 mg × 2) on day one, with subsequent maintenance dosing and adjunctive medications. The patient demonstrated significant symptomatic improvement with decreased COWS scores and expressed interest in long-acting injectable buprenorphine maintenance therapy. Discussion: This represents the first documented case of suspected MP withdrawal successfully managed with buprenorphine macro-induction, demonstrating the potential efficacy of this approach for novel semi-synthetic kratom metabolites when standard withdrawal management protocols are insufficient. Further studies should evaluate long term outcomes and validate findings. Full article

Public debates about psychoactive substances have traditionally been organized around the pharmacology of compounds and the institutional control of supply. In digitally mediated societies, however, the pathways through which people encounter psychoactives are increasingly informational: search engines, recommender systems, social platforms, and—distinctively—conversational AI. These systems do not merely deliver neutral facts. They rank, frame, personalize, and conversationally validate claims in ways that can shape perceived norms, acceptable risk thresholds, and willingness to seek help. This opinion advances the concept of AI-mediated exposure to capture how algorithmic curation and interactive dialogue become upstream determinants of psychoactive-related harms and benefits across the continuum from everyday medicines to non-medical use. From a social-scientific ethics perspective, the central question is not whether AI is “good” or “bad,” but what obligations apply when AI performs interpretive authority in contexts characterized by vulnerability, stigma, and unequal access to trusted expertise. The paper argues for an ethics-centered governance framework grounded in four commitments: epistemic responsibility (how claims are generated, warranted, and communicated), relational responsibility (how users are treated in moments of uncertainty, distress, and stigma), distributive justice (who benefits and who bears risk under unequal conditions), and accountability (how behavior is evaluated, contested, and corrected over time). The aim is to treat conversational AI as a public-facing institution whose design choices must be ethically legible and publicly contestable, oriented toward harm reduction without intensifying surveillance, moralization, or inequity.

Male-biased drug use is a consistent finding in contemporary epidemiology, yet most global evidence derives from urban and industrialized populations. As a result, little is known about gendered substance use in small-scale societies, leaving unresolved whether male-biased drug use reflects universal features of human behavior or is primarily a product of industrialization. To address this gap, we examine ethnographic evidence of female substance use across 171 societies in the Standard Cross-Cultural Sample using 1397 ethnographic cases from the Human Relations Area Files. We document the presence of male and female drug use descriptions, regional and subsistence-based variation, substances associated with women’s use, and the cultural contexts in which female consumption occurs. Results reveal that women’s drug use is consistently less frequent and more culturally regulated than men’s across all world regions and subsistence economies, with variation in magnitude. Exploratory factor and cluster analyses identify four domains structuring female drug-use contexts: prestige-regulated substances, ceremonial and social practices, medicinal use, and high-risk entheogenic rites. Together, these findings demonstrate that low female drug use is a cross-cultural regularity while highlighting patterned variation in the contexts of women’s consumption, providing a comparative foundation for evaluating biocultural, political–economic, and evolutionary explanations of gendered substance use.

Interest in psychoactive substances, including psychedelics, is rapidly expanding in medical, academic, and other popular fields. Despite the classifications established within the psychopharmacological scientific community, certain plants, animals, and fungi, as well as the substances obtained from them, have been misclassified by both the media and academic circles. This opinion piece aims to present arguments to answer the following question: Is CBD a non-psychoactive phytocannabinoid? Hundreds of robust scientific studies published in recent years involving CBD have strengthened its clinical use in the treatment of seizures, anxiety, psychosis, schizophrenia, post-traumatic stress disorder, and addiction. As part of the arguments to answer the question posed, this text provides a historical overview of the classifications of psychoactive substances available to date, and offers reflections on these terminologies and a proposed classification of psychedelics.

Cannabis is one of the most common intoxicants used worldwide. Cannabis is widely consumed worldwide and can lead to visual alterations. However, most of the available information on its effects comes from studies conducted in developed countries, while data remain limited in developing regions such as Morocco, despite its significant role in cannabis cultivation. The aim of this study was to explore multiple visual parameters and self-perceived eyesight in cannabis users in Morocco. A cross-sectional study was conducted between March 2022 and April 2023 in Marrakesh, Morocco, in cannabis consumers. Data collection was performed in two phases. First a hetero-administrated questionnaire was used to collect socio-demographics, intoxicant consumption habit information, and eye health information. Then, several visual acuity tests were performed, including a preliminary examination, a visual function assessment, and an eye health assessment. Ninety-five cannabis users participated in this study. The majority were single (62.1%) males (87.4%). All lived in the Marrakesh-Safi region (100%), and most had daily activities such as having a job or being a student (77.9%). Most had vision conditions like astigmatism or myopia (83.4%). The majority had multiple addictions (66.5%), mainly to tobacco (43.7%). Hashish was the main cannabis type used (57.9%), and smoked cannabis was the principal mode of consumption (94.7%). Many had a family history of cannabis addiction (58.9%). Day light sensitivity (66.3%) and appearance of eye symptoms after cannabis use (90.5%) were declared by the majority. In most cases, no impact on far or near vision or vision impairment due to cannabis use were declared. Our results showed that using cannabis could have significant adverse effects on visual functions. Full article

Adolescent mental health conditions, particularly treatment-resistant depression (TRD), represent a growing public health challenge associated with high morbidity, functional impairment, and elevated suicide risk. Psychedelic-assisted therapies have shown robust antidepressant and transdiagnostic effects in rigorously controlled adult trials. Extending this work to adolescents is scientifically compelling yet ethically complex, given neurodevelopmental vulnerabilities and the paucity of pediatric data. This review examines the historical context of psychedelic use, summarizes adult efficacy and mechanistic insights, explores adolescent-specific opportunities and risks, and considers applications in co-occurring neurodevelopmental disorders. Conventional treatments, including selective serotonin reuptake inhibitors and psychotherapy, are often inadequate for a narrow but substantial subset of clinical phenotypes, prompting interest in novel and rapid-acting interventions. Psychedelic-assisted therapies have shown promising results in adults with refractory mood disorders, yet their applicability to adolescents remains uncertain due to ongoing neurodevelopment and ethical constraints. This review critically examines evidence from adult psychedelic and psychedelic-adjacent interventions, including esketamine, and evaluates their potential relevance to adolescent populations through a developmental, mechanistic, and ethical lens. Rather than advocating for premature clinical adoption, we highlight translational gaps, developmental risks, and research priorities paramount to responsibly assess these approaches in youth.

Cannabis and its derivatives are increasingly popular. The public perception of “cannabis” is commonly related to abuse potential with no sharp distinction to “marijuana”, “cannabinoids”, “hemp”, and cannabis derivatives. Delta 9-tetrahydrocannabinol (THC)—rich cannabis (“marijuana”), needs to be distinguished from hemp and cannabidiol (CBD)—rich; the former is psychotomimetic, while the latter is not, and it is increasingly used as a “health product”; the phytochemical composition makes the difference. However, this is still inadequately addressed. Without a detailed characterization of the components and effects conclusions cannot be generalized and are only applicable to the product used. Cannabis varieties have a highly variable phytochemical composition; the effects cannot always be attributed solely to the “main cannabinoids.” Growth conditions and processing methods also have a significant influence on the properties of the final product, even when the same cannabis variety is used. Therefore, the few comparative studies between extracts and the corresponding pure cannabinoids often produce conflicting results, as numerous preclinical and clinical examples demonstrate. They also show how little attention is paid to the phytochemical profile, even in scientific publications. Both in scientific research and consumer products, the phytochemical profile beyond the main cannabinoids should be disclosed in detail, especially since new cannabis products containing semi-synthetic CBD derivatives have recently entered the market.
