Authorities in the United States (US) have confirmed that tetrahydrocannabinol (THC)-containing products could be playing a role in the current outbreak of lung injury associated with e-cigarette use or vaping. 

More than 800 cases of the mystery illness have now been identified, with 12 deaths reported. More than two-thirds of patients are male.

On Friday (September 27), the US Centers for Disease Control and Prevention (CDC) said that while no single product has been linked to all cases, the latest findings from the investigation suggest THC products play a role in the outbreak. 

Latest data from the CDC’s Morbidity and Mortality Weekly Report (MMWR) show almost eight in 10 people (77 per cent) affected by the illness reported using THC-containing products or both THC- and nicotine-containing products. 

The CDC has recommended that people consider refraining from the use of e-cigarette or vaping products, particularly those containing THC.

“CDC is committed to finding out what is causing this outbreak of lung injury and death among individuals using vaping products,” said Robert R. Redfield, MD, director of the CDC. “We continue to work with FDA and state partners to protect the nation from this serious health threat.”
