Abstract
The present disclosure relates to articles (and the manufacture thereof) that use electrical energy to heat a material to form an inhalable substance, the articles being sufficiently compact to be considered “hand-held” devices. In certain embodiments, the articles can particularly be characterized as smoking articles. The smoking article can be adapted to detect the status of a cartridge portion of the smoking article. The smoking article includes a control body portion having a control body engagement end, wherein the control body portion houses a control component and a power source therein. The article further includes a cartridge body portion that has a cartridge body engagement end configured to removably engage the control body engagement end of the control body portion. The cartridge body portion houses a consumable arrangement and a heating connection operably engaged therewith comprising at least one heating element and a fusible link.
