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