Professor Michael Ussher added, “Vaping products are constantly evolving, and so we need to keep an eye on any new toxins that we need to check for. It’s an ever-evolving field of research.”
The analysis was a collaboration between scientists at Metropolis St George’s, College of London, College of Nottingham, College Faculty London, Kings Faculty London, the US Facilities for Illness Management and Prevention and the UK Well being Safety Company.
