A smoking product including a substantial proportion of tobacco stem material and incorporating carbamide and a saturated fatty acid composition having a carbon chain length of 16-18. The carbamide is present in an amount from 1.0 to 3.0 percent and the fatty acid is present in an amount of from 1.0 to 4.0 percent, by weight, of the stem material. The carbamide and fatty acid impart to the stem material, when it burns, some of the more pleasant taste and smell characteristics of burning tobacco leaf. The stem material may be in its natural state, but crushed, or it may be made into a reconstituted sheet or film. |
