Recent literature suggests potential associations between hallucinogen use and valvular heart disease (VHD) due to prolonged activation of serotonin 5-HT2B receptors, which may lead to valvular fibrosis – a condition also linked to drugs including fenfluramine and pergolide. Despite these concerns, epidemiological studies exploring this association are lacking. This exploratory analysis...

Diante da crescente prevalência dos diagnósticos de transtornos ansiosos no Brasil e no mundo, o presente artigo visa analisar as contribuições das substâncias psicodélicas no tratamento dos transtornos. Por meio de uma revisão narrativa, foram examinados estudos sobre o potencial terapêutico de compostos como LSD, psilocibina, ayahuasca e MDMA. Os resultados colhidos apontam que essas...
Zusammenfassung Substanzkonsumstörungen (SUD) sind chronische Erkrankungen mit hohen Rückfallraten und begrenzter Wirksamkeit etablierter Behandlungen. Vor diesem Hintergrund rückt die psychedelisch-assistierte Psychotherapie (PAP) mit Psilocybin und LSD zunehmend in den Fokus; die Literatur berichtet Hinweise auf mögliche Effekte insbesondere bei AUD und affektiven Symptomen. Ziel der Studie:...
The past two decades have seen a remarkable renaissance in research on psychedelic drugs and ketamine. Following decades of regulatory restriction that severely limited, especially clinical research, a growing body of evidence has shown that psychedelics such as lysergic acid diethylamide and psilocybin can have long-lasting beneficial effects for treatment-resistant depression, drug and...
Major depressive disorder (MDD) remains a global health burden, with over 60% of patients failing to respond adequately to current treatments. Treatment-resistant depression (TRD), a form of MDD, highlights the urgent need for mechanistically novel antidepressants. Psychoplastogens—a class of fast-acting compounds that promote neuroplasticity—are emerging as promising alternatives to...
Psilocybin, psilocin, 5-MeO-DMT, LSD and mescaline are classical hallucinogens whose recreational use has increased over recent decades (Brito-da-Costa et al., 2021; Dinis-Oliveira et al., 2019; Holze et al., 2021; Jiang et al., 2013). However, data on their interactions with cytochrome P450 (CYP450) enzymes remain scarce, despite the potential for clinically relevant drug–drug interactions....
Psychedelic drug use is increasing due in part to local legislative reforms. Understanding the patterns of first-time psychedelic drug use is imperative for informing consumers, healthcare providers, and policy makers. The National Survey on Drug Use and Health (NSDUH) is a repeated cross-sectional nationally representative survey of civilians aged 12 and older. Use estimates are presented for...
The nature and role of the psychological support provided in psychedelic-assisted treatments for psychiatric disorders are currently the object of debate. How this support is conceptualized-as a vector for therapeutic change or framework for risk minimization-has far-reaching consequences in terms of how these treatments should be regulated, delivered, and studied. To determine whether...

AbstractIntroduction Psilocybin, a naturally occurring psychedelic compound found in certain mushroom species, has gained substantial clinical, scientific, and cultural attention in recent years. Despite this growing interest and evolving policy landscape, nationally representative estimates of recent psilocybin use in the United States remain limited. Understanding the current prevalence and...
Psychedelic drugs are serotonergic hallucinogens that can be divided into two types: naturally occurring (psilocybin, psilocin, and N,N-dimethyltryptamine) and synthetic (LSD, MDMA, 2,5-dimethoxy-4-iodoamphetamine, and ketamine). Psychedelics generally work on 5-hydroxytryptamine receptors and might be useful in cognitive enhancement, brain connectivity, neuroplasticity, and neuronal...
