schizophrenia is such a complex topic and it cannot be summed up with one drug it's just not going to happen
but I do believe there's evidence schizo is the result of a dysfunctional NDMA receptor in the brain
the most common drug class associated with that specific receptor is dissacociatives (ketamine,pcp,dxm)
and those can wreck the receptor so dissacociatives are probably out the question so I have no idea
very interesting question though
