Market survey of disposable e-cigarette nicotine content and e-liquid volume

Abstract

Inaccurate labels on some e-cigarette products have prompted calls for routine testing to monitor product label integrity. The objective of this study was to compare label statements of commercial disposable/non-chargeable e-cigarette products for nicotine concentration and e-liquid volume with analytically verified levels. Commercial e-cigarette samples were analyzed for nicotine concentration (N = 51), e-liquid volume and total nicotine content (N = 39). Twenty-three of the 51 samples analyzed for nicotine deviated from their label statements by more than ± 10%. Deviations ranged from -50.1% to + 13.9%. Thirty of the 39 samples analyzed for e-liquid volume deviated from their label statements by more than ± 10%. Deviations ranged from -62.1% to + 13.3%. Only one brand listed total nicotine on the label. In thirty-one of the 39 samples, calculated total nicotine amount in e-liquid deviated from the amounts calculated from the label metrics by more than ± 10%. Deviations ranged from -66.8% to -1.43%. These findings underscore the need for regulatory enforcement of manufacturing quality control and product labeling practices to optimize the harm reduction potential and consumer experience associated with the use of e-cigarette products.

E-cigarettes use and respiratory symptoms in asthmatic and non-asthmatic adolescents – a systematic review

“…In some countries, graphic health warnings on packaging have additionally been made mandatory, following the 2021 World Health Organisation (WHO) guidelines (5) . Studies indicate that although ENDS manufacturers comply with legal requirements (6,7) , and despite many bans, electronic cigarettes are still readily available to young people. In Poland, they can be purchased at special kiosks or stalls in shopping malls, as well as online.…”
