Main targets of ibogaine and noribogaine associated with its putative anti-addictive effects: A mechanistic overview

The biosynthetic pathway of the hallucinogen mescaline and its heterologous reconstruction
Abstract Mescaline, among the earliest identified natural hallucinogens, holds great potential in psychotherapy treatment. Nonetheless, despite the existence of a postulated biosynthetic pathway for more than half a century, the specific enzymes involved in this process are yet to be identified. In this study, we investigated the cactus Lophophora williamsii (Peyote), the largest known natural […]

Examining differences in the effects and contexts of naturalistic psilocybin use for White participants vs. participants of Color: A longitudinal online survey study
This study used data from a large, online longitudinal study of individuals who planned to engage in naturalistic psilocybin use. We used mixed-effects models to assess whether race/ethnicity (White vs. Participant of Color) moderated outcomes related to mental health.
Shame, guilt and psychedelic experience: Results from a prospective, longitudinal survey of real-world psilocybin use
The experience of self-conscious emotions with psychedelics has been explored minimally, but further study in this area may have far-reaching implications for psychological health. The activation of shame-related experiences with psychedelics may pose a unique and context-dependent learning condition for both therapeutic and detrimental forms of shame-related memory reconsolidation.
