Fungal contamination found in disposable vape mouthpieces prompts health warning

A University of Florida study tested 25 disposable vape mouthpieces and found more than 35 different fungi. More than half showed abundant fungal colonisation, and eighty percent of the fungi identified could potentially cause ill health. The researchers note that the enclosed, heated environment helps fungi thrive, making mouthpieces a possible source of exposure.

Researchers cultured samples and compared them with cultures from the users’ mouths to confirm the fungi did not come from the users. They caution that the study is small and cannot prove illness risk. Still, the findings add a new angle to vaping safety, suggesting contamination routes that deserve more robust research and practical steps like regular cleaning.

The study mirrors a broader pattern where early findings test a new product against limited data. A small sample and lab methods limit generalisation, yet the result pushes researchers, regulators, and consumers to look beyond chemical toxicity to micro life inside devices.

This piece invites cautious interpretation. It flags potential risks without exaggerating them and asks for clear guidance on safe use while more evidence is gathered.

Further evidence will determine how seriously this changes vaping guidance.
