An Ohio high school student allegedly punched a teacher so hard during a drug-induced hallucination that he caused "a major brain injury," according to school officials and local reports.

The 15-year-old student at Colerain High School in Cincinnati acted "distraught" after he "ingested an unknown drug" Thursday afternoon before allegedly hitting the teacher, WLWT 5 reported, based on a police report.

The 60-year-old teacher was rushed to the University of Cincinnati Medical Center, where she had her skull cap removed to prevent damage from swelling, according to Fox 19. 

The student reportedly also suffered a "self-inflicted" head injury and fought another student, according to WLWT 5.
