Once lit, the tobacco in a cigarette reaches about 900°C at the tip.
When tobacco burns, it creates light and smoke, which are both visible
to the naked eye. It also releases thousands of invisible chemicals.
Around 100 of these, termed Harmful and Potentially Harmful Constituents
(HPHCs), are thought to be the primary cause of smoking-related
disease.2
One of the reasons many smokers enjoy cigarettes is that they like
nicotine and the flavour of tobacco. A complex set of behavioural and
sensorial rituals, like the hand-to-mouth movement or the process of
exhaling smoke can also make smoking a pleasurable experience for many.
We’re looking to provide adults, who would otherwise continue to smoke,
with less harmful alternatives that deliver nicotine satisfaction
alongside these cues and rituals.The premise is simple. By heating –
without burning – a portion of refined tobacco contained within a stick
(named iD), Pulze creates an inhalable aerosol. This contains nicotine
and tobacco aromas, with substantially fewer and lower levels of the
harmful by-products of tobacco combustion.
Pulze uses a cylindrical, ceramic rod that gently heats the tobacco to a
pre-set temperature, 315 °C in Eco mode and 345°C in Standard mode.
This rod penetrates the iD stick, warming the tobacco stick from the
inside outwards. Three elements are necessary to create the chemical
process of combustion: heat, fuel and oxygen. In a cigarette, tobacco
acts as a fuel which ignites using a high-temperature heat source
(usually from a lighter). The tobacco relies on oxygen in the air to
burn, creating the by-products heat, light, smoke and ash. Fig 1 below
explains this process.
