1. Method for the preparation of a sheet including a homogenized material containing alkaloids, said method comprising:
forming a mixture comprising particles of a material containing alkaloids and starch, and a quantity of a first additive comprising a component selected from the group consisting of water, aerosol-former and binder, wherein the quantity of the first additive is comprised between about 0.1 percent and about 50 percent by weight of the total weight of the mixture;
applying to the mixture a mechanical energy of at least about 20 watt-hour per kilogram of the mixture;
combining the mixture with a quantity of a second additive comprising a component selected from the group consisting of water, aerosol-former, and binder, to form a slurry, comprising:
combining the mixture with a quantity of water comprised between about 55 percent and about 90 percent by weight of the total weight of the slurry; and
forming a sheet from the slurry.
