Lab results reveal what's really in your patients' e-cigarettes

6 out of 10 e-liquids marketed as 'nicotine-free' were found to contain nicotine

Vapers who use nicotine-free e-cigarettes are potentially inhaling not only nicotine but also trace amounts of pesticides and a biological chemical found in urine and faeces, an Australian study has found.

WA researchers purchased 10 different e-liquid products labelled 'nicotine-free' from Australian suppliers and had their chemical composition analysed by an independent commercial laboratory.

Nicotine was detected in six of the e-liquids, including three that had levels comparable to those found in low-dose nicotine e-cigarettes.
