Methods for producing dissolving grade pulp and microcrystalline cellulose from tobacco are provided. The methods include chemical pulping a tobacco input to form a tobacco pulp. Chemical pulping the tobacco input includes combining the tobacco input with a strong base defining a weight from about 5% to about 50% of the tobacco input, and heating the tobacco input and the strong base with an H-factor from about 500 to about 3,300. Further, the methods include bleaching the tobacco pulp to produce a dissolving grade pulp. Bleaching the tobacco pulp may include chlorination of the tobacco pulp with a chlorine dioxide solution, and caustic extraction of the tobacco pulp with a second strong base. A related tobacco-derived microcrystalline cellulose product is also provided, which can be used as a binder, a filler, and/or a texturizer in a tobacco product, such as a smokeless tobacco product.

Cigarette filter rods having individual objects positioned at predetermined intervals therein are prepared by transferring the individual objects from a rotating horizontal pan to a rotating vertical wheel and then depositing the object into a web of filter tow. Each object is positioned within the moving web of tow. The web filter material and the objects positioned within the web are introduced into a rod-forming unit wherein the rod is formed. The rate of feed of the filter tow, the rate of rotation of the horizontal pan and the vertical wheel are controlled relative to one another such that objects are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.

A personal vaporizing unit (PVU) generates a vapor that is inhaled by a user. A substance (e.g. liquid) in a cartridge is vaporized or atomized by a heating element that heats the liquid. When the PVU is activated, and the user provides suction, the liquid to be vaporized is drawn out of the cartridge, through a wick, and is atomized by the wick into a cavity containing the heating element. The cartridge may be removable and utilize different connectors for connecting with the PVU. A seal may be used for the liquid reservoir that can be punctured upon usage.

An aerosol delivery device comprising a control component and a communication interface is provided. The control component controls operation of at least one functional element of the aerosol delivery device in instances in which a flow of air through at least a portion of the at least one housing is detected. The communication interface is coupled to the control component and enables wireless communication. The control component further detects a predefined trigger, and automatically in response thereto, causes the communication interface to broadcast availability of the aerosol delivery device for connection with a capable wireless device. The predefined trigger includes at least one instance in which the flow of air is detected, and excludes user-actuation of any button on the aerosol delivery device.
