The U.S. Food and Drug Administration on Oct. 4 warned consumers not to use vaping products containing THC amid growing concerns over the outbreak of lung illness.
As of Oct. 1, the U.S. Centers for Disease Control and Prevention reported 1,080 lung injury cases related to vaping and confirmed 18 deaths.
The CDC and FDA are investigating the outbreak.
"As this complex investigation continues, we urge consumers to take heed of our warning and stop using THC vaping products, and to not use vaping products of any kind that are purchased off the street or from unknown sources," the FDA said in a statement.
THC is present in a majority of the samples tested, the FDA noted. Of the 578 patients with information on the substances used in vaping products, about 78% used products containing THC with or without nicotine-containing products, the CDC said.
