Tobacco doesn't have much use as an edible plant or herb, as the nicotine levels can very quickly make you sick. However, tobacco smoke is sometimes used as a flavoring agent in dishes and barbecue.

Tobacco leaves can also be steeped in liquids like cream, sugar syrup, or alcohol to extract flavor, similar to how tea leaves are used. Extracts made in this way can be added (in moderation) to dishes as well.
