Anti-nicotine zealots chose safety as their main battleground on e-cigarettes, and it didn’t work out too well for them. Now they seem to be doing the same again with Heat not Burn. Will it be more effective this time? Probably not.
We’ve already seen a lot of research from PMI on the safety of their iQOS device. Now British American Tobacco have released their own work on Glo, which is currently on sale in Japan and South Korea. Glo works on the same concept as iQOS, delivering vapour from heated tobacco that’s held in a cigarette-like stick, and the only real difference in the technology is that Glo heats its sticks to a lower temperature. That means we wouldn’t expect to see a huge difference in its vapour compared to iQOS – and, sure enough, we don’t.
Science and smoking
What BAT were interested in was the potential of Glo vapour to cause DNA changes in human cells. Damage to DNA can kill a cell – but, even worse, it can also cause cancer by making the cell grow and divide abnormally. Smoking is known to cause damage to thousands of genes; the question is, how does Glo compare?
