The impact of classic psychedelics (5-HT2A receptor agonists) on personality traits has been studied for decades, and it has been hypothesized that the mechanisms underlying these changes are linked to agonism at cortical serotonergic 5-HT2A receptors. However, research results are contradictory. Therefore, the present paper aims to systematically evaluate the effects of psychedelics on...

The findings suggest a clinically relevant interaction between ayahuasca and SSRIs, as even modest increases in DMT exposure may intensify serotonergic effects in individuals receiving antidepressant therapy. This study provides a mechanistic and quantitative framework for assessing interaction risks between ayahuasca alkaloids and SSRIs, supporting clinical decision-making and harm-reduction...

As the research field with psychedelic substances grows, it is expected to encompass a more extensive cohort of individuals presenting a spectrum of medical conditions, comorbidities, and unique physiological traits, thereby increasing the likelihood of potential adverse events. Furthermore, it is worth noting that there is a scarcity of the specialized literature regarding procedures to ensure...

Alcohol is the recreational drug most frequently consumed, and its high frequency of use can lead to worsening social, psychological, and domestic issues. The age group most susceptible to alcohol dependence is 18- to 24-year-old youths, demanding interventional tools to target early involvement risks. Ayahuasca seems to be a promising therapeutic tool since evidence suggests it presents...

Ayahuasca is a South American plant hallucinogen rich in the psychedelic N,N-dimethyltryptamine and β-carbolines (mainly harmine). Preclinical and observational studies suggest that ayahuasca exerts beneficial effects in substance use disorders, but these potentials were never assessed in a clinical trial. Single-center, single-blind, feasibility, proof-of-concept study, assessing the effects...
