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.

The apparatus further comprises a second screw conveyor (9, 23) with at least one rotatably driven second screw (9, 27, 28), which is adapted to convey the plant material from a second screw conveyor inlet (6) to a second screw conveyor outlet (7). A fluid connection (5, 38) is provided in between the first screw conveyor outlet (4) and the second screw conveyor inlet (6). The fluid connection is adapted to enable flow of plant material from the first screw conveyor outlet to the second screw conveyor inlet. The first screw conveyor has a first fluid outlet at its downstream side. The second screw conveyor has a second fluid outlet at its downstream side.

A method of forming an oral product includes extruding a mixture, conveying the extruded mixture through one or more pairs of forming rollers, and cutting the extruded mixture into one or more oral products. The mixture can include polymer and at least one flavorant, sweetener, active ingredient, or combination thereof. The extruded mixture forms an extrudate having a predetermined cross-sectional shape. The one or more pairs of forming rollers abut to define a passage there between as each forming roller rotates. The passage has a cross-sectional shape corresponding to the predetermined cross-sectional shape. The method can be performed using a machine including an extruder, one or more pairs of forming rollers, and a cutting device.

A non-tobacco oral nicotine pouch composition is provided, including water in an amount of at least 15% by weight of the pouch composition; nicotine; and at least one sugar alcohol, the pouch composition being free of humectants consisting of alginate, propylene glycol, hydroxypropyl cellulose, and glycerol. An oral pouched nicotine product is also provided, including a saliva-permeable pouch and the non-tobacco oral nicotine pouch composition enclosed in the saliva-permeable pouch.

The disclosure provides for an oral composition, the oral composition including at least one active agent, at least one filler component, and water in an amount sufficient such that the oral composition has a total moisture content of about 15% to about 30% by weight or greater based on the total weight of the oral composition.

Disclosed herein is an inhalable composition, suitable for use in an electronic cigarette device, comprising at least 1 g/L of nicotine and at least 2 g/L of carbon dioxide dissolved or dispersed in a solvent comprising glycerol and water, wherein the molar ratio of carbon dioxide to nicotine is at least 0.1:1; wherein glycerol is present in an amount of at least 40% by weight, based on the total weight of the inhalable composition; wherein water is present in an amount of 1-20% by weight, based on the total weight of the inhalable composition; and wherein propylene glycol, when present, is present in an amount of no more than 10% by weight, based on the total weight of the inhalable composition.

Described is an oral pouched nicotine product having a filling material and a saliva-permeable pouch of a packaging material enclosing the filling material. The filling material includes (a) nicotine containing particles formed from a carrier material, said carrier material includes microcrystalline cellulose, said nicotine containing particles includes a nicotine source, said nicotine containing particles having a sphericity from 0.8 to 1.0 and a diameter from 0.1 mm to 2.0 mm. The oral pouched nicotine product is free from or is substantially free from a constituent having a coating containing a nicotine source and a binder. Also described is a method for preparing the described filling material.

A pouched product including an outer water-permeable pouch defining a cavity and a composition configured for oral use situated within the cavity is provided. The composition is at least partially orally dissolvable, and includes one or more dissolvable fillers in an amount of at least about 45% by weight, based on the total weight of the composition; a humectant in an amount up to about 25% by weight, based on the total weight of the composition; and at least one active ingredient, at least one flavorant, or both at least one active ingredient and at least one flavorant.

There is provided a tobacco flavoured dry powder formulation comprising a plurality of particles comprising a base material and a tobacco flavouring composition, wherein a first ratio by weight of (β-ionone+β-damascenone) to (phenol) in the tobacco flavoured dry powder formulation is greater than 0.25. Further, there is provided a method of producing one such tobacco flavoured powder formulation. The method comprises the steps of: preparing a tobacco starting material; heating the tobacco starting material at an extraction temperature of between 100 degrees Celsius and 160 degrees Celsius for at least 90 minutes; collecting the volatile compounds released from the tobacco starting material during the heating step; forming a liquid tobacco flavouring composition comprising the collected volatile compounds; combining a base material and the liquid tobacco flavouring composition to form tobacco flavoured particles.

A method for identifying converters from tobacco seedling population. The method includes: 1) sowing and cultivating tobacco seeds to be identified for 45-55 days; sampling a plurality of leaf disks from each of 45-55 days old seedlings; 2) incubating the plurality of leaf disks of each seedling in a sealed container at 37° C. for 10-12 hours, thereby obtaining a plurality of incubated tobacco leaves of each seedling; 3) immersing the plurality of incubated tobacco leaves of each seedling in an extractant, extracting alkaloids and obtaining an extract of each seedling; 4) analyzing the amounts of nicotine and nornicotine in the alkaloids extract of each seedling; and 5) automatically recognizing peaks of the alkaloids extract of each seedling, and calculating the percent nicotine conversion (PNC) and the pseudo percent nicotine conversion (PPNC).
