A California resident died Monday from a lung disease caused by vaping, local reports said.

The Tulare County victim, who was not immediately identified, was more than 40 years old and suffered from other illnesses beside the vaping-related affliction, the Los Angeles Times reported.

“With sadness, we report that there has been a death of a Tulare County resident suspected to be related to severe pulmonary injury associated with vaping,” Dr. Karen Haught, a public health officer in the county, told the newspaper.

The person had been using an e-cigarette and was being treated by a doctor for several weeks in the county south of Fresno, according to the report.

“The Tulare County Public Health Branch would like to warn all residents that any use of e-cigarettes poses a possible risk to the health of the lungs and can potentially cause severe lung injury that may even lead to death,” Haught added in her statement, according to the Times.

The death comes amid an increase in vaping-related illness across the US.

At least 64 people in New York state have been sickened by vape products and more than 300 have fallen ill nationwide.

At least six people have died in the US from vaping-related illness.
