Summary
Introduction:
This article presents an analysis of vaping products (VPs) purchased in the USa, Canada, England, and australia, aiming to assess whether differences in regulations are associated with differences in the chemical composition of the VPs. The study focuses on the contents of the unheated liquids used in the products, whether contained in cartridges/pods or as refill liquid.
Key Points:
* VP composition varies by country, likely reflecting both marketplace preferences and country-specific regulations.
* There are differences between nicotine levels claimed on the package and actual levels, particularly in England.
* US liquids had the highest mean nicotine concentration (16.2 mg/mL), while australian and Canadian liquids had no detectable nicotine.
* English liquids had a mean nicotine concentration of 11.9 mg/mL, with about 5% exceeding the UK's 20 mg/mL nicotine limit.
* Substantial country differences were observed in levels of tobacco-specific nitrosamines (TSNas), with the USa being higher than elsewhere.
* Of all products tested, 18.8% contained at least one organic acid, and liquids purchased in England contained far more identifiable flavouring chemicals than those in the other countries.
Main Message:
The study highlights significant variations in the chemical composition of vaping liquids across different countries, which can be attributed to marketplace preferences and country-specific regulations. The findings emphasize the need for consistent regulation and monitoring of vaping products to ensure accurate labeling and reduce health risks associated with their use.
