* Researchers found pesticides, cleaning agents and potentially dangerous chemicals in vaping products
* They also found trace elements of nicotine in products that claim to be nicotine-free
* An independent researcher backed the findings as evidence of the need for greater regulation
Curtin University respiratory physiologist Alexander Larcombe studied 65 common liquids used in vapes from local suppliers that are available in Australia.
Dr Larcombe said the results showed that many vapes contained carcinogenic and other harmful ingredients.
"There is a suite of chemicals in there, many are known to have negative impacts on your lung health," he said.
