Vaping nicotine salt e-liquids closely mimics the experience of smoking a cigarette, results from a clinical study published in journal Internal and Emergency Medicine have concluded.
The research examined healthy adult smokers’ responses to five different Blu vaping products, alongside being evaluated consecutively on different days after using a cigarette as well.
The subsequent rise in nicotine blood levels following the use of all the products were cited as ‘satisfying’ in terms of relieving the desire to smoke.
Other conclusions from the study found Myblu’s 40mg/mL nicotine salt variety appeared to most closely replicate the nicotine hit of a cigarette.
However, current EU regulations permit a maximum of 20mg/mL in e-vapour products.
Dr Grant O’Connell, head of scientific affairs at Imperial Brands, said: “Our findings suggest that e-vapour devices with a higher concentration of nicotine in nicotine salt form may be more effective – and more appealing – to adult smokers switching from cigarettes to vaping.
“In our study, the Myblu Intense 40mg/mL nicotine salt product had the closest nicotine uptake profile to cigarettes, while also providing the greatest relief in subjects’ desire to smoke. However, under current EU regulations, this product is not permitted.
“This potentially limits the effectiveness of vaping as a smoking substitute, especially in the case of heavier smokers – a view shared by the UK Government’s House of Commons Science and Technology committee.”
