Hitting the Reset Button: Ceremonial Use of Peyote and Experiences of Personal Change

Journal of Drug Issues August 22, 2024 Heith Copes, Andrew Hochstetler, Jared Ragland et al. 3 citations

Our aim is to understand how those who use peyote in a naturalistic setting discuss it changed their lives and to what they attribute this change. To do this, we draw on data from a photo-ethnography of people who attended peyote ceremonies in rural Northcentral Alabama. Broadly, we found that participants discussed four core areas of change: reduced drug and alcohol misuse, new perspectives on...

Abstract As a proposed mediator between stigma-related stressors and negative mental health outcomes, HIV-related shame has been predictive of increased rates of substance use and difficulties adhering to antiretroviral treatment among people with HIV. These downstream manifestations have ultimately impeded progress toward national goals to End the HIV Epidemic , in part due to limited success...

Longitudinal associations between psychedelic use and unusual visual experiences in the United States and the United Kingdom.

Journal of Psychopharmacology 2024 Otto Simonsson, Peter S. Hendricks, Cecilia Ud Stenfors et al.

Whereas findings from case reports and cross-sectional studies suggest that naturalistic psychedelic use may be associated with unusual visual experiences that occur after the acute pharmacological effects have subsided, such findings need to be replicated in longitudinal studies to better understand potential cause-and-effect relationships. To investigate longitudinal associations between...
