psychotomimetic

The “psychotomimetic” model of what hallucinogens do is not considered useful/valid at present but more dissociative agents like ketamine and PCP may indeed cause a more accurate “model psychosis.”

Not only was there the idea that these drugs could be psychotomimetic and represented models of psychosis, but simultaneously other theories were being proposed suggesting the potential use of these same drugs in the treatment of mental disorders.
