A study into the impact of flavoured e-cigarettes, on allergic airways disease, suggests that some flavours may worsen the severity of diseases such as asthma.

The researchers found some flavoured e-cigarettes, even in the absence of nicotine, can worsen disease severity.

"The exact effects on features of asthma were dependent upon the specific flavour, suggesting not all flavoured e-cigarettes will have the same consequences on lung health," Dr Chapman said.

In this study the flavour Black Licorice exaggerated airway inflammation whereas Cinnacide had the opposite effect, suppressing airway inflammation. Additionally, Cinnacide increased airway sensitivity and Banana Pudding flavour exaggerated the level of tissue scarring. All e-cigarette liquids containing nicotine suppressed airway inflammation, consistent with the known anti-inflammatory properties of nicotine.
