Can dopamine antagonists such as Thorazine that are used to treat schizophrenia and bipolar be used to upregulate dopamine in the long term in healthy (non schizophrenic or bipolar) users to get a similar effect as a stimulant high without inducing neurotoxicity? Due to tolerance buildup of the dopamine blocker, my assumption is that it should result in dopamine upregulation when dopamine antagonist use is stopped.
As an example, in extremely high doses of methamphetamine, meth induces temporary schizophrenia (skin picking, crank bugs, paranoia, hallucinations, etc), and extremely similar, if not exact, effects to bipolar, which are the only two neurological diseases resulted from dopamine over-production and release. Over time, tolerance to meth builds up and it stops being effective, unless it is stopped for a period of time resulting in reverse-tolerance. Can this same dopamine downregulation effect be used in dopamine antagonists as dopamine upregulation, creating the same euphoric feeling resulted from meth use or bipolar hypomania if the dopamine antagonist is taken for a period of time then stopped?
