Title: Body of tobacco with a deposit of particles added thereto

Abstract: To increase the effectiveness of the filter, the tobacco has mixed therewith and deposited thereon particles of a water-insoluble, hydrophobic, moisture-laden, negative charge-imparting substance. Cigarettes made with tobacco thus treated furnish a number of advantages without being associated with the filter of the invention.
