Nicotine extraction and delivery

10148_hnb3
Different methods of releasing nicotine from tobacco. Nicotine may be combined with flavouring and aerosol agents to form an inhalable aerosol stream.

Nicotine is the main pharmacologically active compounds found in the tobacco leaf and the main reason that consumer use tobacco products.

To ensure nicotine delivery by tobacco heating products, the tobacco used may be blended and treated to aid its thermal release. In addition, release of nicotine and other volatile substances including flavour compounds from tobacco is based on some well-known thermophysical processes that have been commonly used in herbal extraction and food processing. Not all of these processes can be made into a hand-held electronic system, therefore current commercial tobacco heating devices predominantly use heat to distil and evaporate the nicotine and other volatile substances.
