Transcript of E-Cigarettes and Air Quality - Is there 'Passive Vaping'?
We measured the chemicals in the air BEFORE, DURING and AFTER three people vaped in an office over 165 minutes.
The vaper retains up to 99% of the nicotine inhaled from an e-cigarette, so hardly any is re-leased into the surrounding air.
"There is no evidence of direct harm from passive exposure to e-cigarette vapour.”– UK National Health Service
"There is no evidence for passive vaping based on current scientific knowledge."– French Government
Formaldehyde is almost always present in the air around us, no matter where we are
DID YOU KNOW ?
WHAT HAPPENS WHEN YOU VAPE INDOORS ?
Scented candles produce 10 times more formaldehyde than e-cigarettes
WHAT DID WE FIND ?
WHY DOESN’TNICOTINE INCREASE?
Up to 99% retained
