psychoplastogen

noun1

1. •
   Any of a group of small molecule drugs (notably including some psychedelics) that produce rapid and long-lasting effects on neuronal structure and function and whose use is intended to produce therapeutic benefit after a single dose.

   • The fact that LSD, psilocybin, and so forth act as psychoplastogens—agents that increase the plasticity of the mind—is part of what explains their therapeutic effects (Ly et al. 2018, Olson 2018). — 2021
