Haha yes! Psychiatric medication, that purely abstract pill that does not affect the physical body in any way, only enters the mind!

Serotonin is among other things a nausea and thermoregulation neurotransmitter, and has to do with cognition. Most serotonin in the body is synthesized in the gut – a highly enervated endothelial membrane – transported by platelets, and metabolized in the lung.

SARS-CoV-2 is known to damage endothelium, known to cause really weird platelet and blood clotting issues like platelet necroptosis and infection and alteration of bone marrow platelet progenitor cells, known to cause lung injury. In a whole bunch of ways.
