Abstract
A heat not burn consumable () is provided. The consumable includes a tubular vapour generating member () defining a channel therethrough. At least an active portion of the vapour generating member is configured to be heated by a heater to produce vapour. The tubular vapour generating member has an inlet to the channel at a first end of the consumable, the first end of the consumable being for cooperation with a heating device. The active portion of the vapour generating member has a sidewall which has a thickness greater than 0.1 mm. This allows for rapid and consistent heating of the vapour generating member. The active portion comprises an amount of an active substance which is between 0.0001 milligrams per mm{circumflex over ( )}2 and 0.02 milligrams per mm{circumflex over ( )}2 of said internal surface area. The vapour generating member has an overall length which is greater than 50% of a total length of the consumable. This may allow for efficient manufacture of the consumable. The consumable also includes an inactive structural tube in axial abutment with the tubular vapour generating member and located downstream of the vapour generating member. A wrapper overwraps the vapour generating member and at least a portion of the inactive tube. This may allow for efficient manufacture of the consumable.
