Adverse events associated with classic psychedelics and MDMA: a real-world population-based study using the WHO pharmacovigilance database (VigiBase)
Psychiatry Research – December 29, 2025
Summary
Lysergic acid diethylamide (LSD) and MDMA (Ecstasy) carry significant risks for substance abuse and addiction, a global pharmacovigilance analysis reveals. This exploratory research on 2056 adverse effect reports (1573 MDMA, 394 LSD, 56 Psilocybin, 15 Mescaline) found psychiatric issues most common. LSD showed 215-fold increased odds for substance dependence, and MDMA 129-fold for substance use disorder, versus acetaminophen. Overdoses were rare (1.1-1.7%). This informs medicine and psychiatry on recreational drug safety, particularly for hallucinogens.

Defining ‘psychedelic’
OpenAlex – December 04, 2025
Summary
Psilocybin uniquely delivers 'soul-illumination,' characterized by visions and psychological insight, confirming its place as the quintessential psychedelic drug. Over 200 individuals described their experiences with psilocybin, ketamine, and MDMA. Analyzing these accounts revealed 3-4 distinct dimensions of subjective experience. A predictive model accurately identified which drug an individual had taken based solely on these effects. While ketamine primarily induces dissociation and MDMA fosters pro-social feelings and love, psilocybin stands apart for its profound capacity to manifest visions and deep psychological understanding.

Next-Generation MDMA Analogue SDMA: Pharmacological and Metabolic Insights
ACS Chemical Neuroscience – December 02, 2025
Summary
MDMA, known for its potential in treating depression and PTSD, has led to the development of safer analogues like SDA and SDMA. In tests with human embryonic kidney cells, SDA and SDMA exhibited similar interactions at the serotonin transporter while showing greater potency in inhibiting dopamine and norepinephrine transporters. Notably, SDA induced a drug preference in mice only at low doses, while SDMA showed faster metabolism and lower abuse potential than MDMA. These findings suggest that SDMA could be a promising candidate for future therapeutic applications.
