Abstract: Smokable products made of tobacco and/or another smokable material, which comprise natural substances having an antioxidative effect and/or naturally identical synthetic products thereof. These natural substances are selected according to the invention from hydroxycinnamic acids and their esters and depsides, plant phenols which can be derived from hydroxycinnamic acids, polymers of hydroxycinnamic alcohols, further natural substances of plant origin which have antimutagenic and aromatizing properties and are combined with vitamins, their precursors and/or derivatives having an antioxidative effect, and further vitamins having an antioxidative effect which are complexed with eukaryotic cell cultures. Processes for the preparation of products of this type are furthermore described. Compared with conventional smokable products, the products have a distinctly decreased risk potential.
