More than a thousand people reported lasting health effects after being exposed to teargas during protests in Portland, Oregon, last summer, according to a newly published scientific study.
Nearly 900 people reported abnormal menstrual cycles, including intense cramping and increased bleeding, that began or persisted days after their initial exposure to the teargas. Hundreds of others complained of other negative health impacts, including severe headaches, nausea, diarrhea, and mental health concerns.
