Abstract
Methods for creating concentrated plant material solution, including combining ethanol-soluble, water-insoluble concentrated plant material with ethanol to define mixtures and reducing the amount of ethanol in the mixtures until the mixtures have viscosities compatible for use with electronic cigarettes. Some examples include combining ethanol-soluble, water-insoluble concentrated plant material, hydrocarbon bases, and liquid solutions containing ethanol to define mixtures, removing the hydrocarbon bases from the mixtures, and reducing the ethanol content of the mixtures until the mixtures define viscosities compatible for use with electronic cigarettes. Some examples include extracting solute from source materials and including the extracted solute in the ethanol-soluble, water-insoluble concentrated plant material.
