NONE of the current theories being experimented with on patients have a concrete, proven scientific basis with some such as the decades-long SSRI scam have actively harmed patients and created physical dependence/addiction and actively causing harm to patients and their families (eg, SSRI-induced suicides).
I trust science, but I don't trust scientists any more than I trust any other human with their money, career, and reputation on the line. I trust the FDA and pharmaceutical company ethics even less (eg, Bayer knowingly selling HIV-infested drugs to hemophiliacs, saying Oxycotin is non-addictive, or the revolving door that allows non-working SSRIs to be released and marketed as working despite all evidence to the contrary).
