Abstract
Tobacco tissue is puffed by admixing with it hot water, preferably in the form of droplets, in amounts which are substantially completely absorbed by the tobacco in five minutes or less and thus cause puffing of the tobacco cell walls, and freeze drying the resulting tobacco to retain its puffed condition.
