INDIANAPOLIS (AP) — Indiana health officials are reporting two more state residents have died of severe lung injuries linked to vaping.

The new deaths reported Thursday by the Indiana State Department of Health brings the total number of vaping-related deaths in the state to three since Sept. 6.

The agency says the deaths occurred in adults and were confirmed by the Centers for Disease Control and Prevention. No additional details about the patients were provided.

The CDC Thursday reported the number of vaping-related illnesses in the U.S. has reached about 1,300 with at least 26 deaths. Most who got sick said they vaped products containing THC, the marijuana ingredient that causes a high, but others said they vaped only nicotine.

The CDC is advising Americans to refrain from using any vaping products.
