Method and system for providing a heat-not-burn tobacco product

A heat-not-burn tobacco aerosol source member for producing an inhalable aerosol, comprising:

• a first heating section comprising a first hollow structure with a first end and a second end, the first end and second end comprising a liquid impermeable but vapor permeable barrier to allow movement of a vaporized aerosol from the first end through the second end, the first heating section containing a liquid aerosol precursor;
• a second heating section comprising a second hollow structure with a mouth end and a heated end, the mouth end and heated end each comprising a liquid impermeable but vapor permeable barrier to allow movement of the vaporized aerosol from the first heating section and vapors formed from a solid tobacco substrate or a non-tobacco plant material, the vapors being formed in the second heating section from heat transferred by the vaporized aerosol from the first heating section to a first thermal, vapor permeable liquid barrier layer that contacts the heated end;
• the second heating section containing the solid tobacco substrate, or the non-tobacco plant material;
• and
• the first thermal barrier comprising a porous material that is vapor permeable but liquid impermeable located between the first heating section and the second heating section and which substantially reduces heat transfer from the first heating section to the second heating section while permitting flow of the vaporized aerosol from the first heating section into the second heating section.

• and
• a paper layer is positioned outside of the first and second heated sections.
