Introduction to

tobacco heating products

Most toxic substances in cigarette smoke are formed by the decomposition of tobacco when it burns.

Heating tobacco instead of burning it, in theory, should produce an aerosol that is much less harmful than cigarette smoke but still has an authentic tobacco taste.

How our tobacco heating product works

Our tobacco heating product (THP), glo, is a precisely engineered handheld device with a two-zone heating chamber. A specially designed tobacco rod is inserted into the device. When the device is switched on, a rechargeable lithium-ion battery supplies energy to the heaters, which have a maximum temperature of 240°C (a burning cigarette can reach over 900°C).

The tobacco is heated sufficiently to release nicotine and other compounds to form an aerosol, without any ash or burned smell associated with a lit cigarette.

And to ensure the tobacco doesn’t go stale, the staged changes in temperature from glo’s zonal heating work in concert to extract the best flavour from the tobacco rod – all controlled by smart electronics.

Because the tobacco is heated instead of burned, the resulting aerosol comprises mainly water, glycerol, nicotine and tobacco flavours – dramatically different to cigarette smoke.

How glo works

As with vapour products, our THPs undergo extensive testing before making it to market. We have found that, in stark contrast to cigarette smoke, aerosol from tested THPs contains substantially fewer and lower levels of toxic substances (90-95%), and in several laboratory tests of cultured cells was found not to cause DNA mutations, to exhibit 90% less cytotoxicity and was negative for tests of potential tumour promoting effects. 1,2

Furthermore, using the THP causes minimal teeth staining3 and, owing to its enclosed design and lower operating temperatures, the device doesn’t smolder between puffs so has negligible impact on surrounding air and other people in the vicinity.

We have also developed a hybrid device which combines tobacco heating and vaping technology. The glo iFuse contains tobacco, which is why we classify it as a tobacco heating product.

The device heats cartridges which contain not only tobacco, but also a pharmaceutical-grade, flavoured nicotine liquid solution. The nicotine-containing aerosol produced by this heating process is channelled over the tobacco to deliver a tobacco taste.

The information provided above does not necessarily mean that THPs are less harmful than other tobacco products.
