An aerosol-generating tobacco-containing composition, preferably provided in a form of a foam or mousse, and an aerosol-generating article including the composition, are provided. The composition includes particulate tobacco material and lipid, wherein the lipid is medium-chain triglyceride, and a ratio of the medium-chain triglyceride to the particulate tobacco material on a dry weight basis is between 1:3 and 1:5.

An electrolytic gas suction tool includes: a battery; a control substrate which controls power supply from the battery; a pair of positive and negative electrodes which are electrically conducted to or cut off from a positive electrode and a negative electrode of the battery by the control substrate; an electrolysis tank which is capable of storing water and into a lower part of which the pair of positive and negative electrodes are inserted in the mounted state; and a heater device which is heated to generate nicotine containing steam upon receiving the power supply from the battery by the control substrate.

A composition enclosed in a pouch to form a pouched product configured for oral use is provided, the composition including a filler in an amount of at least 20% by weight, based on the total weight of the composition, and at least one active ingredient, at least one flavorant, or a combination thereof. The composition is loaded within the pouch at a density of about 0.45 g/cm.sup.3 or higher. Further provided are methods of preparing the pouched product.

An aerosol-forming substrate is provided, including: a) one or both of cellulose and cellulose derivatives; b) an aerosol-former present in an amount of 20 weight percent to 58 percent on a dry weight basis based on a total amount of the aerosol-forming substrate; c) from 0 weight percent to 5 weight percent of tobacco on a dry weight basis based on the total amount of the aerosol-forming substrate; d) a nitrogen-containing nucleophilic compound; and e) a disaccharide. An aerosol-generating article including a substrate portion containing the aerosol-forming substrate is also provided. An aerosol-generating system is also provided.

An aerosol-generating substrate for vaping includes a semi-solid substrate, wherein up to about 1.0% of the total weight percentage of the aerosol-generating substrate is comprised of one or more carboxylic acids dissolved in an alcohol solution. A method of manufacturing the aerosol-generating substrate and a use thereof in an aerosol-generating substrate for vaping are also provided.

A method of treating tobacco material with superheated steam to reduce the nicotine content of the tobacco material after the treatment compared to the nicotine content of the tobacco material before the treatment. Also provided is treated tobacco material which has been contacted with superheated steam to reduce its nicotine content, as well as the use of superheated steam to treat tobacco and tobacco industry products that include the treated tobacco material.

Compositions made from combinations including an hydrated ionic clay and a tobacco material are described herein. Methods of manufacture, as well as methods of extracting nicotine from these compositions are also described. The compositions can be used to prepare liquid vaporizable materials by extracting nicotine from tobacco material and directly from the tobacco material and into a liquid vaporizable material.

Compositions include an aqueous organic-based gellant system and nicotine or a salt thereof. The compositions are readily prepared and stored in cartridges or used directly in a device for delivering nicotine to a user.

A saturation sensor measures at least one electrical characteristic of the wick between the heating element and the probe wire at a first time and a second time, wherein the at least one electrical characteristic includes a resistance, a capacitance, or both a resistance and a capacitance. Control circuitry is configured to cause the nicotine e-vaping device to: calculate a refill rate at which the nicotine pre-vapor formulation flows onto the wick based on the at least one electrical characteristic at the first time and the at least one electrical characteristic at the second time; determine that the refill rate is less than a threshold refill rate; and output a low nicotine pre-vapor formulation alert in response to determining that the refill rate is less than the threshold refill rate.

Provided herein, inter alia, are compositions including sol-gels and nicotine. The compositions are readily prepared and stored in cartridges or used directly in a device for delivering nicotine to a user.
