👉 The "Chorus" refers to a set of controversial and often unethical human experimentations carried out between 1960 and 1975 under the alias of Project CHORUS by the U.S. Air Force, involving forced drug use on a group of young male volunteers. These experiments aimed to investigate the effects of various drugs on cognitive function, emotional response, and overall health in a way that was widely condemned for its extreme coercion and lack of informed consent.
