Dimethyltryptamine (DMT) is responsible for the psychedelic effects of ayahuasca. According to the results of a phase IIa clinical trial published in Nature Medicine, this molecule improved depressive symptoms in adults with depression after one dose. The trial included 34 people, 17 of whom received intravenous DMT. This second group showed greater improvements in depressive symptoms than the control group. After two weeks, in the second part of the trial, DMT was administered to all participants and the antidepressant effects lasted for three months. Adverse effects were mainly pain at the injection site, nausea and transient anxiety.

The American Psychiatric Association has unveiled the new features of the forthcoming Diagnostic and Statistical Manual of Mental Disorders (DSM) in five articles published in The American Journal of Psychiatry. Among the highlights are the proposed change of name — it will become the Diagnostic and Scientific Manual — and the intention for it to be more dynamic, incorporating biomarkers for diagnosis and integrating the socioeconomic, cultural and environmental determinants of health. According to the authors, the aim is to enable a more personalised and inclusive clinical practice, aligned with scientific rigour. The most recent update was published in 2022 with the DSM-5-TR, and specialists are currently unaware of the date of the next edition, as they reported during a briefing with journalists.

According to a study published in the journal JAMA Health Forum, the use of the benzodiazepine lorazepam by the character Victoria Ratliff in the series The White Lotus was associated in the United States with an increase in Google searches for this medication, including queries about how to obtain it online. The series generated 1.6 million more searches than usual over a 12-week period. Although the study reflects searches for information and not actual consumption, the abuse of anti-anxiety drugs is a fact: illegal sales of benzodiazepines have increased in the United States, and Spain leads the rankings in terms of consumption.
