Heavily used high-puff disposable vapes linked to more toxic aldehydes, study finds
A UC Riverside study found that heavily used high-puff disposable e-cigarettes accumulate toxic aldehydes in remaining liquid, including methylglyoxal and formaldehyde, which caused notable damage to human lung cells; methylglyoxal was significantly more toxic than acetaldehyde. Results suggest puff count and device use cycle dramatically affect chemical exposure, calling for regulatory testing across full device lifespans and caution in consumer use of high-puff devices.
