In some exemplary embodiments, control circuitry 55 of control system 58, once charged, provides power for a desired (or alternatively, determined) number of draws until the energy in power source 50 is depleted and / or drops below a certain threshold, after which control circuitry 55 reconnects control circuitry 55 to the external charging device.

[0071] In an exemplary embodiment, the first non-nicotine e-vapor section 12 is disposable. In this embodiment, the first non-nicotine e-vapor section 12 may be disposed of after depletion of the non-nicotine pre-vapor formulation 21 in the reservoir 62. In an exemplary embodiment, the first non-nicotine e-vapor section 12 is not disposable. In an exemplary embodiment, the non-nicotine e-vapor device 10 is a single section, and the power section 14 and the structure of the first e-vapor section 12 are included in the single section. In an exemplary embodiment, the non-nicotine e-vapor device 10 includes two or more sections.

[0072] 6 is an illustration of a cross-sectional view of the first non-nicotine e-vaping section 12 in an exemplary embodiment. Previously described reference numerals will generally not be described again here for the sake of brevity. In the exemplary embodiment, the first housing 13 and the inner housing 33 enclose the internal elements of the first non-nicotine e-vaping section 12. In the exemplary embodiment, the inner housing 33 defines at least one vent 30.

[0073] In one embodiment, reservoir 62 is defined by a first reservoir housing (wall) 37 and a second reservoir housing (wall). In the exemplary embodiment, first reservoir housing 37 includes a distal end 37a. Distal end 37a slides against an inner wall 39a of second reservoir housing 39 to couple first reservoir housing 37 and second reservoir housing 39 via a friction-fit connection. In the exemplary embodiment, a distal-most end 45 of second reservoir housing 39 contacts a ledge 47 of first housing 13, where a cutout area 43 retains a gasket 41 to form a fluid-tight seal between first reservoir housing 37 and second reservoir housing 39. In the exemplary embodiment, reservoir 62 is defined by one continuous wall and / or housing, or two or more walls and / or housings. In an exemplary embodiment, the capacity of the reservoir 62 provides sufficient non-nicotine pre-vapor formulation 21 for the first non-nicotine e-vapor section 12 to produce approximately 10 to 20 draws before discarding the first non-nicotine e-vapor section 12. In an exemplary embodiment, the capacity of the reservoir 62 provides sufficient non-nicotine pre-vapor formulation 21 for the first non-nicotine e-vapor section 12 to produce 20 or more draws before discarding the first non-nicotine e-vapor section 12.

[0074] In the exemplary embodiment, the first non-nicotine e-vapor section 12 includes a channel 65 between the reservoir 62 and the chamber 72. In the exemplary embodiment, the first reservoir housing 37 defines one or more channels 65. In the exemplary embodiment, the channel 65 includes one or more first channels (first microchannels) 66. The first channels 66 are defined to exist between the reservoir 62 and the wick 64. In the exemplary embodiment, the one or more first channels 66 include only one channel, two channels, or two or more channels. In the exemplary embodiment, the one or more first channels 66 enable the wick 64 to transport a flow 67 of the non-nicotine pre-vapor formulation 21 from the reservoir 62 to the wick 64 due at least in part to capillary forces generated by the wick 64. In exemplary embodiments, the one or more first channels 66 enable the wick 64 to transport a flow 67 of the non-nicotine pre-vapor formulation 21 from the reservoir 62 to the wick 64 due, at least in part, to capillary forces caused by the small diameter of the one or more first channels 66. In exemplary embodiments, the flow 67 of the non-nicotine pre-vapor formulation 21 is at least in part assisted by an airflow 69 entering the reservoir 62, as described below.

[0075] In an exemplary embodiment, the one or more first channels 66 include at least two channels. The at least two channels reduce the likelihood that the one or more first channels 66 will be partially or completely blocked by air bubbles, which would impede or block the flow 67 of the non-nicotine pre-vapor formulation 21 from traveling through the one or more first channels 66. In an exemplary embodiment, the wick 64 does not extend directly into the reservoir 62. In an exemplary embodiment, there is no capillary structure or wicking system between the reservoir 62 and the wick 64 or within the one or more first channels 66, and the sole mode of transport of the non-nicotine pre-vapor formulation 21 from the reservoir 62 to the wick 64 is via exchange through the one or more first channels 66.

[0076] In an exemplary embodiment, the channel 65 includes one or more second channels (air passages) 68. In an exemplary embodiment, the one or more second channels (second microchannels) 68 include only one channel, two channels, or more than two channels. In an exemplary embodiment, the one or more second channels 68 are defined between the reservoir 62 and the chamber 72. In an exemplary embodiment, the one or more first channels 68 are disposed adjacent to the wick 64. In an exemplary embodiment, the one or more second channels 68 circumnavigate the wick 64 and / or the heater 60. In an exemplary embodiment, the one or more second channels 68 allow an airflow 69 to travel from the chamber 72 to the reservoir 62 as the non-nicotine prevapor formulation 21 is expelled from the reservoir 62. In an exemplary embodiment, the airflow 69 is facilitated and / or assisted by pressure generated within the chamber 72. The pressure results from the incoming airflow 31 and the through flow of non-nicotine vapor 73 within the chamber 72. In exemplary embodiments, the airflow 69 is facilitated and / or assisted by a displacement (vacuum) force as the non-nicotine pre-vapor formulation 21 is displaced and depleted from the reservoir 62. In exemplary embodiments, one or more second channels 68 are defined between the reservoir 62 and the non-nicotine vapor channel 70, or another portion of the first non-nicotine e-vapor section 12 other than the chamber 72, or the ambient air.

[0077] In exemplary embodiments, the first total cross-sectional flow area of ​​the one or more first channels 66 is greater than the second total cross-sectional flow area of ​​the one or more second channels 68. In exemplary embodiments, the ratio of the first total cross-sectional flow area of ​​the one or more first channels 66 to the second total cross-sectional flow area of ​​the one or more second channels 68 is between about 10:1 and 4:1, or between about 9:1 and 5:1, or about 7:1. In exemplary embodiments, the first total cross-sectional flow area of ​​the one or more first channels 66 is greater than about 0.5 mm 2 from 1.5 mm 2 Between or about 0.75 mm 2 to 1.25 mm 2Between or about 1 mm 2 In an exemplary embodiment, the second total cross-sectional flow area of ​​the one or more second channels 68 is about 0.075 mm 2 from 0.225 mm 2 Between or about 0.1 mm 2 from 0.2 mm 2 Between or about 0.15 mm 2 In an exemplary embodiment, each of the one or more second channels 68 is small enough that the non-nicotine pre-vapor formulation 21 cannot pass through the one or more second channels 68. The size of each of the one or more second channels 68 depends on factors including the smoothness of each of the one or more second channels 68, the material defining the one or more second channels 68 (first reservoir housing 37), the surface tension of the non-nicotine pre-vapor formulation 21, etc. In an exemplary embodiment, assuming that the one or more second channels 68 include two channels, the flow path cross-sectional area of ​​each of the channels 68 is approximately 0.12 mm 2 Less than or about 0.1 mm 2 Less than or about 0.075 mm 2 Other ranges of values ​​for the sizes of the one or more first channels 66 and the one or more second channels 68 and the ratio of the total cross-sectional flow area of ​​the one or more first channels 66 to the one or more second channels 68 are contemplated.

[0078] In the exemplary embodiment, the wick 64 is on a wall 76 of the chamber 72. In the exemplary embodiment, the wall 76 is at least partially formed by the first reservoir housing 37. In the exemplary embodiment, the wick 64 is embedded in the wall 76 by an indentation 78 in the wall 76. In the exemplary embodiment, the heater 60 heats the vicinity of the wick 64. That is, the heater 60 is sufficiently close to the wick 64 that the heater 60 can at least partially vaporize the non-nicotine pre-vapor formulation 21 absorbed in the wick 64.

[0079] In an exemplary embodiment, the wick 64 is a thin pad. In an exemplary embodiment, the wick 64 is rectangular. In an exemplary embodiment, the wick 64 is square, circular, or another shape. In an exemplary embodiment, the wick 64 is sized to absorb enough non-nicotine pre-vapor formulation 21 to produce one draw from the first non-nicotine e-vapor section 12. In an exemplary embodiment, the wick 64 is made of a porous and / or absorbent material capable of absorbing the non-nicotine pre-vapor formulation 21. In an exemplary embodiment, the wick 64 is made of a fibrous material, filaments, including glass or ceramic filaments. In an exemplary embodiment, the wick 64 does not extend into the reservoir 62. In an exemplary embodiment, the wick 64 does not extend into the one or more first channels 66. In an exemplary embodiment, the wick 64 is about 5 mm long. 3 ~15mm 3 , or approximately 7.5 mm 3 ~12.5mm 3 , or about 10 mm 3 of non-nicotine pre-vapor formulation 21. In an exemplary embodiment, heater 60 and wick 64 vaporize non-nicotine pre-vapor formulation 21 in approximately 0.2 seconds.

[0080] In the exemplary embodiment, the heater 60 is in direct contact with the wick 64. In the exemplary embodiment, the heater 60 is on the surface of the wick 64. In the exemplary embodiment, the heater 60 includes a flat surface 80, as described in more detail in FIG. 8 . The flat surface 80 traverses at least a portion of the surface of the wick. In the exemplary embodiment, the flat surface 80 of the heater 60 faces the interior of the chamber 72. In the exemplary embodiment, the heater 60 is on a first side of the wick 64 opposite a second side of the wick 64. The second side of the wick 64 faces the one or more first channels 66.

[0081] In an exemplary embodiment, at least one vent 30 includes an outlet 30a (discharge end) that directs incoming airflow 31 at a heater 60. In an exemplary embodiment, outlet 30a is heated near heater 60. In an exemplary embodiment, outlet 30a is located approximately 1.0 mm to 2.0 mm from heater 60, approximately 1.2 mm to 1.5 mm from heater 60, or approximately 1.3 mm from heater 60. In an exemplary embodiment, outlet 30a faces heater 60. In an exemplary embodiment, outlet 30a directs incoming airflow 31 at a center position 71 of heater 60 (see FIG. 8 ). In an exemplary embodiment, a flow of non-nicotine vapor 73 within chamber 72 passes across at least a portion of heater 60. In an exemplary embodiment, facing outlet 30a at heater 60 creates a turbulent flow condition at heater 60. This allows for uniform mixing of the incoming airflow 31 with the non-nicotine vapor from the heater 60. In an exemplary embodiment, the incoming airflow 31 is also directed toward, into, or near one or more second channels 68. This causes the incoming airflow 31 to provide air pressure that further causes the airflow 69 to move from the chamber 72 to the reservoir 62. In an exemplary embodiment, the incoming airflow 31 enters the chamber 72 in a first direction, which causes the incoming airflow 31 to flow away across the heater 60 in a second direction, the first direction and the second direction being approximately perpendicular to each other. In an exemplary embodiment, the first direction is approximately perpendicular to the flat surface 80 of the heater 60 (see FIG. 8 ). In an exemplary embodiment, the second direction is approximately parallel to the flat surface 80 of the heater 60. In the exemplary embodiment, the size of the flow cross-sectional area of ​​the at least one vent 30 is adjusted to control the desired RTD of the first non-nicotine e-vaping section 12. In the exemplary embodiment, the inlet 30b of the at least one vent 30 is not directly exposed to ambient air during operation of the non-nicotine e-vaping device 10 because ambient air instead first passes through the at least one air inlet 18 and the at least one air inlet 36 before reaching the at least one vent 30.

[0082] In the exemplary embodiment, a non-nicotine vapor channel 70 is defined within the first non-nicotine e-vaping section 12. In the exemplary embodiment, the non-nicotine vapor channel is defined at least in part by the first housing 13, the first reservoir housing 37, and the second reservoir housing 39. In the exemplary embodiment, the non-nicotine vapor channel 70 is in fluid communication with the chamber 72 and the one or more outlets 16, and the non-nicotine vapor channel 70 directs the flow of non-nicotine vapor 73 from the chamber 72 to the one or more outlets 16.

[0083] In the exemplary embodiment, post 74 and electrical connection 75 electrically connect electrical connection 28 to heater 60 . First Non-Nicotine Section and General Fluid Flow Through the Device, According to Some Embodiments

[0084] In an exemplary embodiment, airflow 31 enters the non-nicotine e-vapor device 10 through at least one air inlet 18 (FIG. 4), passes through at least one air inlet 36, the interior space 29 (FIG. 5), at least one vent 30, and enters the chamber 72. In the chamber 72, the airflow 31 entrains vapor that has at least partially volatilized from the heater 60. The resulting non-nicotine vapor 73 travels from the heater 60 through a non-nicotine vapor channel 70 before leaving the non-nicotine e-vapor device 10 via one or more outlets 16. In an exemplary embodiment, during use of the first non-nicotine e-vapor section 12, a flow 67 of non-nicotine pre-vapor formulation travels from the reservoir 62 through one or more first channels 66 to the wick 64 and is at least partially volatilized by the heater 60, while an airflow 69 enters the reservoir 62 via one or more second channels 68. FIG. 7 is an illustration of another cross-sectional view (perspective AA of FIG. 6 ) of the first non-nicotine e-vaping section 12 according to an exemplary embodiment. Previously described reference numerals will generally not be described again here for brevity. In the exemplary embodiment, the distal end 33 a of the inner housing 33 at least partially defines the chamber 72. In the exemplary embodiment, the inner housing 33 fits into the first housing 13, with a first contact surface 77 of the inner housing 33 contacting a second contact surface 76 to ensure the inner housing is properly positioned within the first housing 13. In the exemplary embodiment, the inner housing 33 is retained within the first housing 13 via a friction fit.

[0085] In the exemplary embodiment, outlet 30a faces heater 60 and wick 64, and outlet 30a is located substantially in the center of center position 71 of heater 60 (as shown in FIG. 8).

[0086] In the exemplary embodiment, the distal end 37a of the first reservoir housing 37 has an oval cross section, as shown in FIG.

[0087] In an exemplary embodiment, the second reservoir housing 39 is adhesively connected to the interior of the first housing 13, and the first reservoir housing 37 is adhesively connected to the second reservoir housing 39, via application of adhesive at one or more surface locations where the second reservoir housing 39 and the first housing 13 contact each other, and at one or more surface locations where the first reservoir housing 37 and the second reservoir housing 39 contact each other. In an exemplary embodiment, the interior housing 33 is adhesively connected to the first reservoir housing and / or the first housing 13 using application of adhesive at the surface contact locations. In an exemplary embodiment, the adhesive (sealant) is a silicone-based adhesive or other suitable sealant, providing a liquid-tight and airtight seal. In an exemplary embodiment, the first reservoir housing 37, the second reservoir housing 39, the interior housing 33, and the first housing 13 are held together via a friction (press) fit, with no adhesive used to assemble the first e-vaping section 12.

[0088] FIG. 8 is an illustration of a cross-sectional view (perspective B-I of FIG. 7 ) of the first non-nicotine e-vaping section 12 according to an exemplary embodiment. In this view, elements along the wall 76 of the chamber 72 are shown in greater detail. Previously described reference numerals will generally not be described again here for brevity. In an exemplary embodiment, the heater 60 comprises a heating element 61. In an exemplary embodiment, the heating element 61 is a flat metal structure. In an exemplary embodiment, the heating element 61 is a thin and / or linear structure. In an exemplary embodiment, the heating element 61 is wave-shaped (e.g., sinusoidal) or "S"-shaped. In an exemplary embodiment, the heating element 61 is shaped to maximize surface contact with the wick 64. In an exemplary embodiment, the heating element defines an opening 82 in the heating element 61 that exposes a surface area of ​​the wick 64 to the interior of the chamber 72. In an exemplary embodiment, the heater 60, or the heating element 61 of the heater 60, forms a substantially flat surface 80. In an exemplary embodiment, heater 60 is constructed of iron-aluminide (e.g., FeAl or FeAl). In one embodiment, heater 60 is a wire coil, a flat body, a ceramic body, a solid wire, a cage of resistive wire, or other suitable form configured to vaporize non-nicotine pre-vapor formulation 21. In at least one exemplary embodiment, heater 60 is formed of any suitable electrically resistive material or materials. In an exemplary embodiment, heater 60 is a ceramic heater having an electrically resistive layer on its outer surface.

[0089] In the exemplary embodiment, a central portion 71 of the heater 60, which is the portion of the heater 60 facing the outlet 30a, comprises a flat surface 80. In the exemplary embodiment, the central portion 71 of the heater 60 corresponds to a central region of the heater 60 and / or heating element 61.

[0090] In the exemplary embodiment, the heater 60 includes an electrical connection 84. In the exemplary embodiment, the electrical connection 84 is electrically connected to the power source 50. In the exemplary embodiment, the electrical connection 84 of the heater 60 is electrically connected to the electrical connection 75 of the first non-nicotine e-vaping section 12 and to the post 74, which is in turn electrically connected to the electrical connection 28 of the first non-nicotine e-vaping section 12 and to the electrical connection 44 of the power unit 14. In the exemplary embodiment, one of the electrical connections 44 is electrically connected to the power source 50, and the other of the electrical connections 44 is connected to the control circuitry 55. Thus, via the electrical connection 28 of the first non-nicotine e-vaping section 12 and via the post 74 and the electrical connection 75, the control circuitry 55 of the control system 58 can cause the power source 50 to selectively send current to the electrical connection 44 of the power unit to energize the heater 60.

[0091] In the exemplary embodiment, the one or more second channels 68 are on the sides of the wick 64. In the exemplary embodiment, the one or more second channels 68 are not covered by the wick 64, and the one or more first channels 66 are covered by the wick 64. Advantages of Some Exemplary Embodiments

[0092] Advantages of some exemplary embodiments include:

[0093] [A. Independence of Gravity] Several factors, including the relatively small mass of the non-nicotine pre-vapor formulation, the small size of the one or more first channels 66, and the geometric shape of the elements of the first non-nicotine e-vapor section 12, at least partially help to make the non-nicotine e-vapor device 10 less or not reliant on gravity to operate the non-nicotine e-vapor device 10 and convey the non-nicotine pre-vapor formulation 21 to the wick 64 and heater 60. That is, the orientation of the non-nicotine e-vapor device 10 does not affect or change the performance of the non-nicotine e-vapor device 10. These factors at least partially help to mitigate leakage and ensure that a desired and uniform amount of the non-nicotine pre-vapor formulation 21 is applied to the wick 64 and vaporized by the heater 60.

[0094] [B. Reducing the size of the power source] Several factors, including the relatively small mass of the non-nicotine pre-vapor formulation and the geometric shape of the elements of the first non-nicotine e-vaping section 12, allow for a relatively small power source 50, which can assist in the charging scheme of the non-nicotine e-vaping device 10. [Non-nicotine prevapor formulation embodiments]

[0095] In exemplary embodiments, flavoring (at least one flavorant) and / or non-nicotine compounds are included in the non-nicotine pre-vapor formulation 21. In exemplary embodiments, the non-nicotine pre-vapor formulation 21 is a liquid, solid, dispersion, and / or gel formulation including, but not limited to, water, beads, a solvent, an active ingredient, ethanol, a botanical extract, a natural or artificial flavor, and / or at least one non-nicotine vapor former, such as glycerin or propylene glycol.

[0096] The non-nicotine compound does not contain nicotine. In an exemplary embodiment, the non-nicotine compound does not contain tobacco or is not a tobacco-derived compound. In an exemplary embodiment, the non-nicotine compound is cannabis or contains at least one cannabis-derived component. In an exemplary embodiment, the cannabis-derived component includes at least one of a cannabis-derived cannabinoid (e.g., a phytocannabinoid, or a cannabinoid synthesized by the cannabis plant), at least one cannabis-derived terpene, at least one cannabis-derived flavonoid, or a combination thereof.

[0097] In exemplary embodiments, the non-nicotine compound is in the form of or contained within a solid, semi-solid, gel, hydrogel, or combination thereof, and the non-nicotine compound is injected into or co-mixed with or bound within the non-nicotine pre-vapor formulation 21. In exemplary embodiments, the non-nicotine compound is in the form of or contained within a liquid or partially liquid form including an extract, oil, tincture, suspension, dispersion, colloid, alcohol, a general non-neutral (slightly acidic or slightly basic) solution, or combination thereof, and the non-nicotine compound is injected into or mixed within or bound within the non-nicotine pre-vapor formulation 21. In exemplary embodiments, the non-nicotine compound is a component of the non-nicotine pre-vapor formulation 21. In exemplary embodiments, the non-nicotine pre-vapor formulation 21 is in or is part of a dispersion, suspension, gel, hydrogel, colloid, or combination thereof, and the non-nicotine compound is a component of the non-nicotine pre-vapor formulation 21.

[0098] In exemplary embodiments, the non-nicotine compounds undergo a slow, natural decarboxylation process over an extended period of time at low temperatures, including room temperature (72°F) or below. In exemplary embodiments, when the non-nicotine compounds are exposed to elevated temperatures, particularly in the range of about 175°F or above, for periods of time (minutes or hours at relatively low pressures, such as 1 atmosphere), the non-nicotine compounds may undergo a significantly enhanced decarboxylation process, with decarboxylation on the order of 50% or more. At even higher temperatures (above about 240°F), rapid or instantaneous decarboxylation may occur with high decarboxylation rates (50% or more), but may cause degradation of some or all of the chemical properties of the non-nicotine compounds.

[0099] In exemplary embodiments, the at least one non-nicotine vapor former of the non-nicotine pre-vapor formulation includes a diol (such as propylene glycol and / or 1,3-propanediol), glycerin, and combinations or subcombinations thereof. Various amounts of the non-nicotine vapor former may be used. For example, in some exemplary embodiments, the at least one non-nicotine vapor former is included in an amount ranging from about 20% by weight based on the weight of the non-nicotine pre-vapor formulation 21 to about 90% by weight based on the weight of the non-nicotine pre-vapor formulation 21 (e.g., the non-nicotine vapor former is in a range of about 50% to about 80% by weight, or about 55% to about 75% by weight, or about 60% to about 70% by weight). As another example, in exemplary embodiments, the non-nicotine pre-vapor formulation 21 includes a weight ratio of diol to glycerin ranging from about 1:4 to 4:1, and the diol is propylene glycol, 1,3-propanediol, or a combination thereof. In an example embodiment, the ratio is about 3:2. Other amounts or ranges are possible.

[0100] In exemplary embodiments, the non-nicotine pre-vapor formulation 21 contains water. Various amounts of water may be used. For example, in some exemplary embodiments, water may be included in an amount ranging from about 5% by weight based on the weight of the non-nicotine pre-vapor formulation 21 to about 40% by weight based on the weight of the non-nicotine pre-vapor formulation 21, or from about 10% by weight based on the weight of the non-nicotine pre-vapor formulation 21 to about 15% by weight based on the weight of the non-nicotine pre-vapor formulation 21. Other amounts or percentages may be used. For example, in exemplary embodiments, the remaining portion of the non-nicotine pre-vapor formulation 21 that is not water (and is not a non-nicotine compound and / or flavorant) is a non-nicotine vapor former (described above), which is 30% to 70% by weight propylene glycol, with the balance of the non-nicotine vapor former being glycerin. Other amounts or percentages may be used.

[0101] In exemplary embodiments, the non-nicotine prevapor formulation 21 contains at least one flavorant in an amount ranging from about 0.2% to about 15% by weight (e.g., the flavorant may range from about 1% to 12% by weight, or from about 2% to 10% by weight, or from about 5% to 8% by weight). In exemplary embodiments, the at least one flavorant contains a volatile cannabis flavor compound (flavonoid). In exemplary embodiments, the at least one flavorant contains a flavor compound instead of or in addition to a cannabis flavor compound. In exemplary embodiments, the at least one flavorant may be at least one of a natural flavorant, an artificial flavorant, or a combination of a natural flavorant and an artificial flavorant. For example, the at least one flavorant may include menthol, wintergreen, peppermint, cinnamon, clove, combinations thereof, and / or extracts thereof. Additionally, flavors can be included to provide herbal flavors, fruit flavors, nut flavors, liqueur flavors, roast flavors, mint flavors, savory flavors, combinations thereof, and other desired flavors.

[0102] In exemplary embodiments, the non-nicotine compound may be a naturally occurring component of a medicinal plant or a plant with medically recognized therapeutic effects. The medicinal plant may be the cannabis plant, and the component may be at least one cannabis-derived component. Cannabinoids (phytocannabinoids) are an example of cannabis-derived components. Cannabinoids interact with receptors in the body to produce various effects. As such, cannabinoids are believed to have various medicinal properties. Cannabis-derived materials may include leaf and / or flower material from one or more cannabis plants, or extracts from one or more cannabis plants. In exemplary embodiments, the one or more cannabis plants include Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some exemplary embodiments, the non-nicotine prevapor formulation 21 contains a mixture of cannabis and / or cannabis-derived components that are, or are derived from, 60-80% (e.g., 70%) Cannabis sativa and 20-40% (e.g., 30%) Cannabis indica.

[0103] Examples of cannabinoids derived from cannabis include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiol acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclo (CBL), cannabichromene (CBC), and cannabigerol (CBG). Tetrahydrocannabinolic acid (THCA) is the precursor to tetrahydrocannabinol (THC), and cannabidiol acid (CBDA) is the precursor to cannabidiol (CBD). Tetrahydrocannabinolic acid (THCA) and cannabidiol acid (CBDA) may be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, via heating. In an exemplary embodiment, the heat from the heater 60 may cause a decarboxylation reaction to convert tetrahydrocannabinolic acid (THCA) in the non-nicotine pre-vapor formulation 21 into tetrahydrocannabinol (THC) and / or may cause a decarboxylation reaction to convert cannabidiolic acid (CBDa) in the non-nicotine pre-vapor formulation 21 into cannabidiol (CBD).

[0104] In instances where both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present in the non-nicotine prevapor formulation 21, decarboxylation and the resulting conversion result in a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least 50% (e.g., at least 87%) of the tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC) via a decarboxylation process during heating of the non-nicotine prevapor formulation 21 for vaporization. Similarly, in instances where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in the non-nicotine prevapor formulation 21, decarboxylation and the resulting conversion result in a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD). At least 50% (e.g., at least 87%) of the cannabidiol acid (CBDA) may be converted to cannabidiol (CBD) via a decarboxylation process during heating of the non-nicotine prevapor formulation 21 for vaporization.
