Psychedelic microdosing in rats shows beneficial effects

The growing popularity of microdosing — taking tiny amounts of psychedelic drugs to boost mood and mental acuity — is based on anecdotal reports of its benefits. Now, a study in rats by researchers at the University of California, Davis suggests microdosing can provide relief for symptoms of depression and anxiety, but also found potential negative effects. The work is published March 4 in the journalĀ ACS Chemical Neuroscience.

“Prior to our study, essentially nothing was known about the effects of psychedelic microdosing on animal behaviors,” said David Olson, assistant professor in the UC Davis departments of Chemistry and of Biochemistry and Molecular Medicine, who leads the research team. “This is the first time anyone has demonstrated in animals that psychedelic microdosing might actually have some beneficial effects, particularly for depression or anxiety. It’s exciting, but the potentially adverse changes in neuronal structure and metabolism that we observe emphasize the need for additional studies.”
