Another person has died from a severe respiratory illness linked to vaping, bringing the national death toll to nine.
The patient, a Kansas resident, was a man over age 50 who had underlying health conditions, according to a statement from the Kansas governor's office announcing the death.
This is the second such death in that state. Other states that have reported vaping-related lung illness deaths are California, Illinois, Indiana, Minnesota, Missouri and Oregon.
The Centers for Disease Control and Prevention has reported 530 cases nationwide, and state health departments are investigating hundreds more.
The Food and Drug Administration's Office of Criminal Investigations previously launched an investigation into the products behind the illnesses, but has come up with no single device or ingredient that links all of the cases.
