Abstract: A method for forming a reconstituted tobacco substrate, the method including: receiving a tobacco input comprising a first tobacco material and a tobacco stem material (100); selectively extracting the tobacco stem material by combining the tobacco stem material with an aqueous liquid to forma tobacco stem extract and a tobacco stem pulp (102); separating and discarding the tobacco stem extract (104); forming the tobacco stem pulp into a web (106); combining the web with the first tobacco material to forma reconstituted tobacco substrate (106); and optionally adding an aerosol forming material to the web or the reconstituted tobacco substrate (108).

Abstract: A nicotine-containing pharmaceutical product configured for insertion into the mouth of a user of that product is provided. The product can have an outer water-permeable pouch, a nicotine-containing pharmaceutical composition situated within the outer water-permeable pouch, and product identifying information relating to the nicotine-containing pharmaceutical composition. The information can be presented such that a user of the product can discern the identifying information by visually inspecting the product and thereby differentiate or identify certain nicotine-containing pharmaceutical products. The product identifying can be, for example, printed, imprinted or dyed on the outer water-permeable pouch, positioned within the outer water-permeable pouch, or attached to the outer water-permeable pouch.
