Psychiatrists think they need to do something funky with the 5HT receptors and dopamine receptors and also try and lower the side effects of their new drugs.
The NMDA receptor role in the development of schizophrenia and drug is needing of more research with nature and life induced neuro degeneration being a hazard of the trade with the current approach.
the adaptive biochemistry of some plants can work in unique and novel useful ways.
In China I'm certain there is a herb that has good stable antipsychotic properties working with the NMDA receptor that also aids ones health against nerodegenerative issues.
This is likely also to have a better tolerability profile.
So i say this to some fictitious elite if you don't want people to need to relieve themselves with cannabis so much then you have to find such optimal's with nature.
