Harris wanted to join the United States Marine Corps, but his application was rejected shortly before the shootings because he was taking the drug fluvoxamine, an SSRI antidepressant, which he was required to take as part of court-ordered anger management therapy. Harris did not state in his application that he was taking any medications. According to the recruiting officer, Harris did not know about this rejection. Though some friends of Harris suggested that he had stopped taking the drug beforehand, the autopsy reports showed low therapeutic or normal (not toxic or lethal) blood-levels of Luvox (fluvoxamine) in his system, which would be around 0.0031–0.0087 mg/ml, at the time of death. After the shootings, opponents of contemporary psychiatry like Peter Breggin claimed that the psychiatric medications prescribed to Harris after his conviction may have exacerbated his aggressiveness.
