ABSTRACT The method for expanding tabacco lamina comprises contacting the tobacco with an organic expansion agent, heating the thus contacted tobacco in a closed first vessel so that the temperature of the agent is above the boiling point of the agent at a lower release pressure, and suddenly venting the first vessel into a second vessel which is at said release pressure prior to the venting. By this means the fill volume of the tobacco is increased by a least 50%.
