However, the repeated theme of temporal distortion amongst many archives of psychedelic experiences strongly supports the notion that psychedelic drugs do, in some way, impact the underlying neurochemistry of time perception. This brief paper discusses examples of how psychedelics can change time perception and offers suggestions for further research. date: 2005 date_type: published refereed: TRUE referencetext: References Barušs, I., & Vletas, S.
