Vaping is linked to deadly lung infections

Vaping may raise people’s risk of pneumonia and other deadly bacterial infections, a leading lung scientist has warned.

Professor Jonathan Grigg has found that the chemical propellants and nicotine used in ecigarettes both have a powerful effect on lung cells, effectively opening them up to infection by the bacteria that cause pneumonia.

“People who vape should consider vaccination against bacterial pneumonia,” said Grigg, professor of paediatric respiratory and environmental medicine at Queen Mary University of London.

Ecigarettes work by heating a mix of propylene glycol (the propellant), nicotine and various flavourings, creating a vapour that the user inhales.
