Abstract: An aerosol generator device for delivering an aerosol of a nicotine salt is provided. The aerosol generator comprises: (i) a mouth end; (ii) a first chamber containing a porous material wetted with liquid nicotine, (iii) a second chamber containing a porous material wetted with a solution of a volatile acid, (iv) a third chamber in fluid communication with the first and second chambers, leading to the mouth end, and (v) an outer housing defining a passageway for air through said device. A nicotine vapor can be produced by drawing air along the passageway and through the porous material wetted with liquid nicotine. An acid vapor can be produced by passing air along the passageway and through the porous material wetted with a solution of a volatile acid. Then, the nicotine vapor and the acid vapor can be admixed in the third chamber to form an aerosol of a nicotine salt, which can be drawn out through the mouth end.

Abstract: Cellulose acetate fibers can be modified to have physical imperfections and then incorporated into cigarette filter plugs as filtering materials. Cellulose acetate fiber modification can be achieved by etching with a gas phase etchant or a liquid phase etchant comprising hydrogen peroxide. Modification of cellulose acetate fibers may be performed at various stages during the manufacture of cigarette filter plugs. Furthermore, cigarette filter plugs containing modified cellulose acetate fibers can also have spaced apart slits along the length of the cigarette filter plugs.

Abstract: Delivery of additives in a smoking article is provided through thermally degradable, robust immobilized additive inserts. Additives can be immobilized in an elongated device or an insert, wherein the elongated device or the insert is sufficiently robust to allow the elongated device or the insert to be manually or machine inserted into a smoking article while maintaining the structure of the elongated device or the insert. By providing additives in the form of thermally degradable immobilized additive inserts, migration and/or loss of the additives in a smoking article prior to smoking can be reduced.

Abstract: An aerosol powder delivery device, a method of producing or delivering aerosol particles, a method of making a delivery device, and an inhaler kit are provided. The device can be used to produce an aerosolizable powder by breaking or deagglomerating the aerosolizable powder into aerosol particles for inhalation. The aerosol particles can be produced by mechanically agitating or shaking a hollow device with the aerosolizable powder and a second powder to mechanically break or loosen aerosol particles from the aerosolizable powder. Thus, a small, lightweight, simple, sealed and stable device without complex moving parts, external power sources or heat is provided to aerosolize powder into aerosol particles for transmucosal delivery into a mouth upon inhalation.

Abstract: A virtual or augmented reality smoking system is provided herein. A smoker using the system can experience a virtual reality of smoking by puffing on a cigarette shaped article and experiencing the taste or aroma from the article while simultaneously viewing a generated image of a burning cigarette and exhaled and sidestream smoke. Additionally, the room environment may be simulated to give the experience of smoking in a setting of the smoker's choice (virtual reality) or the image of a burning cigarette and smoke may be superimposed on a live or natural image of the smoker's environment (augmented reality).

Abstract: Disclosed are methods and compositions for preparing tobacco such that components of tobacco tar are reduced, while maintaining the total tar delivery of a composition or device containing tobacco treated with one or more natural tar diluents. Artificial tar diluents can also be used in combination with one more natural tar diluents. The tobacco compositions have decreased levels of tobacco specific nitrosamines and/or other components found in tar when the composition is smoked, while maintaining the total tar delivery of the smoking article, such as a cigarette, when using a tar diluent at a level sufficient to achieve desired taste qualities.

Abstract: A surface-modified activated carbon is provided to reduce the amount of free fine carbon particles among the activated carbon. By surface-modifying the activated carbon with a layer, the activated carbon can have increased mechanical strength and the fine carbon particles among the activated carbon can be fastened to the layer. Therefore, the layer allows for the level of free fine carbon particles among the activated carbon to be reduced. Surface-modified activated carbon can be used in smoking articles so as to allow for adsorption by the activated carbon with reduced free fine carbon particles in the smoking article and the smoke produced.
