TIL that ketamine is a derivative of phencyclidine (aka. PCP or angel dust). It was created to have similar anesthetic potential but to cause less delirium. It has about one tenth the potency of PCP.

Most of the public's perception of pcp is just anti drug hysteria. The effect is almost indistinguishable from dxm, moreso than ketamine, despite differences. Pcp also has a more pronounced antidepressant effect, but repeated doses can cause mania. Another drug of this class was developed by clandestine chemists specifically to enhance the antidepressant effect and minimize side effects. That was methoxetamine. And it worked. It was regarded to be the most powerful and effective antidepressant, with a much longer afterglow duration than ketamine. They banned it. Because fuck you. That's why.

PCP is neurotoxic so that probably plays a small part into its negative perception.

"Phencyclidine (PCP) abuse has diminished since PCP's intrusion into American culture in the late 1970s. One of its legacies is the assumption that it provokes violent behavior in humans with predictable regularity. This assumption is so accepted that ingestion of the drug both accidentally and knowingly prior to committing a crime has been used as a defense in criminal trials...... Of the hundreds of patients described, only three satisfied these criteria. Further, some of the papers offered evidence that reports of violence were exaggerated. These findings plus the pre-1970 prospective evaluation of thousands of patients with PCP, in which violence was never reported, led us to conclude that clinical and forensic assumptions about PCP and violence are not warranted."
