CONFIRMED: Psilocybin promotes dendritic spine growth persisting at least one month after a single exposure (Shao et al. 2021). Whether the specific changes at La Chorrera constituted lasting neuroplasticity in the therapeutic sense is not determinable. Whether these are attributable to the substances specifically, the experience, or the passage of time through a significant life event is not separable.Citation
