From 2017 – 2022, law enforcement seizures across the United States of mushrooms containing psilocybin increased dramatically, according to a new study funded by the National Institute on Drug Abuse (NIDA). The number of law enforcement seizures increased from 402 seizures in 2017 to 1,396 in 2022. In addition, the total weight of psilocybin mushrooms seized by law enforcement increased from...
Despite distinct classes of psychoactive drugs producing putatively unique states of consciousness, there is surprising overlap in terms of their effects on episodic memory and cognition more generally. Episodic memory is supported by multiple subprocesses that have been mostly overlooked in psychopharmacology and could differentiate drug classes. Here, we reanalyzed episodic memory confidence...
Contemporary mind and brain sciences provide theories and data that seem to confirm a hypothesis about human nature that we might formulate as follows. Human life is conditioned by a need that is no less important than elementary biological needs (such as survival and reproduction) or universal forms of social competition: the need to build and, indeed, defend a subjective identity whose...
Mindfulness-based cognitive therapy (MBCT) offers promise as a group-based intervention to alleviate posttraumatic stress disorder (PTSD) and depression symptoms in traumatized Black adults. Given the high level of barriers that exist for low-income Black adults, virtual delivery of MBCT may be helpful. This pilot randomized controlled trial assessed feasibility and acceptability of an adapted...
Ketamine, an N-methyl-d-aspartate (NMDA) receptor antagonist, has attracted attention for its acute and sustained antidepressant effects in patients with depression. Hydroxynorketamine (HNK), a metabolite of ketamine, exerts antidepressant effects without exerting ketamine's side effects and has attracted much attention in recent years. However, the detailed pharmacological mechanism of action...
Psychedelics are being increasingly examined for their therapeutic potential in mood disorders. While the acute effects of ayahuasca, psilocybin, and lysergic acid diethylamide (LSD) last over several hours, inhaled N,N-Dimethyltryptamine (DMT) effects last around 10 min, which might provide a cost- and time-effective alternative to the clinical application of oral psychedelics. We aimed at...
The 5-methoxy-N-methyl-N-isopropyltryptamine (5-MeO-MiPT, known online as "Moxy") is a new psychedelic tryptamine first identified on Italian national territory in 2014. Its hallucinogen effects are broadly well-known; however, only few information is available regarding its pharmaco-toxicological effects. Following the seizure of this new psychoactive substances by the Arm of Carabinieri and...
Ayahuasca is an original Amazonian brew made from the vines and leaves of Psychotroa viridis and Banisteriopsis caapi. Both P. viridis and B. caapi give this brew its unique psychedelic properties which have been revered over centuries. In recent years, ayahuasca has gained attention as a potential therapeutic tool for mental health disorders, including substance abuse and depression. The...
Psilocybin, a classic hallucinogen, may eventually be approved by the United States Food and Drug Administration for treatment-resistant depression. However, we are aware of only one published national survey of American psychiatrists regarding their opinions about hallucinogens and hallucinogen-assisted therapy, conducted by our group in 2016. Here, we report a repeat survey, using virtually...
The religious or spiritual value of contemplative practices and the use of psychedelics is not intrinsic to experiences obtained through them and is instead relational—a function of how they alter consciousness. In support of that claim, I first present a nonreductive, nondualist Buddhist account of consciousness that calls critically into question the merits of both physicalist and...
