Description

VAPORIZABLE CANNABINOID COMPOSITIONS
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No.
63/428180 filed on November 28, 2022. The contents of the aforementioned application are incorporated by reference herein.
FIELD

[0002] The present application pertains to the field of vaporizable cannabinoid compositions.
More particularly, the present application relates to liquid compositions for an electronic vaporizer containing cannabinoids and terpenes, methods for preparing such compositions, and cartridges comprising such compositions.
BACKGROUND

[0003] Cannabis is a genus of flowering plants that has been used by humans for various purposes, such as medicines, ritual, recreation and textiles. The flowers of the cannabis plant include glandular trichomes, in which phytocannabinoids are produced.

[0004] Over 100 phytocannabinoids produced by the cannabis plant have been identified to date. A notable phytocannabinoid is tetrahydrocannabinolic acid (THCA), which when decarboxylated, is transformed into tetrahydrocannabinol (THC). THC is a psychoactive substance that users may use in order to get a "high" when the cannabis flower is smoked, but has also been shown to be useful for other purposes, such as an appetite stimulant for people with AIDS and an antiemetic for people undergoing chemotherapy (see e.g., product monographs for dronabinol approved by the FDA).

[0005] In addition to phytocannabinoids, the cannabis plant also produces terpenes and terpenoids (collectively referred to herein as "terpenes" unless context dictates otherwise).
Terpenes are organic compounds produced in a variety of plants, many of which are consumed in human diets and/or used in perfumes. They contribute to the aromas and flavors Date Recue/Date Received 2024-03-26 of different cannabis cultivars. The terpenes found in cannabis share a precursor with phytocannabinoids.

[0006] Currently, the most common method of utilizing cannabis is through inhalation of combusted dried cannabis flower. However, reactions occurring during the combustion of the dried flower can result in the formation of undesirable by-products. By-products can include formaldehyde, acetaldehyde, acrolein and other potentially carcinogenic compounds.

[0007] In other combusted plant products, such as tobacco products, some users have switched from traditional combustion cigarettes to alternative delivery mechanisms in an effort to reduce their exposure to such compounds. For example, an alternative to tobacco cigarettes is an electronic vaporization devices (a "vape" or an "e-cigarette"). In tobacco, the active inhalable ingredient ("AM) is nicotine. Electronic vaporization devices vaporize a liquid composition containing Ails (such as nicotine) into a "vapor" in order to permit inhalation by the user. These vapors are often produced at temperatures such that the formation of potentially harmful by-products is reduced as compared to a conventionally combusted analog.

[0008] However, it has been found that conventional liquid compositions containing cannabinoids require the presence of carrier oils, also known as cutting agents or diluents, to achieve a viscosity compatible with cartridges used in electronic vaporization devices. These carriers may not be desirable for inhalation and may cause adverse health effects. Moreover, conventional vaporizable liquid compositions generally contain no more than 85-87 wt%
THC, limiting the potency of the compositions. The presence of minor cannabinoids and carriers also dilutes the taste provided by terpenes which are also present in conventional liquid compositions.

[0009] There is a need for improved liquid compositions containing cannabinoids for use in electronic vaporization devices.
SUMMARY OF THE INVENTION

[0010] In one aspect, there is provided a liquid composition for an electronic vaporizer comprising:

Date Recue/Date Received 2024-03-26 (a) at least about 90 wt% of a mixture of one or more cannabinoids, the mixture of one or more cannabinoids comprising at least about 85 wt% tetrahydrocannabinol (THC) and at least about 0.1 wt% tetrahydrocannabinolic acid (THCA); and (b) from about 3 wt% to about 7 wt% of a mixture of one or more terpenes.

[0011] In another aspect, there is provided a method for preparing a liquid composition for an electronic vaporization device comprising:
(a) thermally decarboxylating THCA in crystalline form to obtain a THC oil;
and (b) mixing the THC oil with (i) a cannabis distillate oil comprising at least about 50 wt% THC, and (ii) one or more terpenes, wherein the liquid composition comprises from about 50 wt% to about 60 wt% of the THC
oil, from about 35 wt% to about 45 wt% of the cannabis distillate oil, and from about 3 wt%
to about 7 wt% of a mixture of the one or more terpenes.

[0012] In another aspect, there is provided a liquid composition for an electronic vaporization device prepared by the methods described herein.

[0013] In another aspect, there is provided a cartridge configured to operatively couple with an electronic vaporizer comprising the liquid compositions described herein.
DETAILED DESCRIPTION

[0014] The present inventors have developed vaporizable liquid compositions that maximize psychoactive potency (from high THC content) and flavour (from terpenes). A
THC oil of high purity (at least 85 wt% THC), also known as a "liquid diamond", may be obtained by decarboxylation of THCA in crystalline form (so-called THCA "diamonds").
Surprisingly, it has been discovered that by combining about 50 wt% to about 60 wt% of such a THC oil with about 35 wt% to about 45 wt% of a cannabis distillate oil high in THC, and from about 3 wt%
to about 7 wt% of a mixture of the one or more terpenes, the inventors have obtained a Date Recue/Date Received 2024-03-26 vaporizable composition of superior potency and flavour compared to conventional vaporizable compositions. The combination of a "liquid diamond" THC oil and a cannabis distillate oil has the advantage of minimizing levels of minor cannabinoids and maximizing THC content, resulting in increased psychoactive potency of the composition, without raising the viscosity of the composition to an unusable level, i.e., one that results in an elevated cartridge failure rate when vaped. Moreover, the presence of about 3 wt% to about 7 wt%
terpenes is sufficient to impart desirable flavour and simultaneously maintain the viscosity of the predominantly THC-containing composition at a level suitable for use in vape cartridges without the addition of a carrier or cutting agent. Higher levels of terpenes may lead to an undesirably overpowering taste in the vaporizable composition.
Definitions

[0015] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0016] As used in the specification and claims, the singular forms "a", "an"
and "the" include plural references unless the context clearly dictates otherwise.

[0017] As used herein, whether in the specification or the appended claims, the transitional terms "comprising", "including", "having", "containing", "involving", and the like are to be understood as being inclusive or open-ended (i.e., to mean including but not limited to), and they do not exclude unrecited elements, materials or method steps. Only the transitional phrases "consisting of' and "consisting essentially of', respectively, are closed or semi-closed transitional phrases with respect to claims and exemplary embodiment paragraphs herein. The transitional phrase "consisting of" excludes any element, step, or ingredient which is not specifically recited. The transitional phrase "consisting essentially of' limits the scope to the specified elements, materials or steps and to those that do not materially affect the basic characteristic(s) of the invention disclosed and/or claimed herein.

[0018] It is to be understood that any numerical value inherently contains certain errors necessarily resulting from the standard deviation found in the respective testing Date Recue/Date Received 2024-03-26 measurements. Also, as used herein, the term "about" generally means within 10%, 5%, 1%, or 0.5% of a given value or range. Alternatively, the term "about" means within an acceptable standard error of the mean when considered by one of ordinary skill in the art. Unless indicated to the contrary, the numerical parameters set forth in the present disclosure and attached claims are approximations that can vary as desired. At the very least, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

[0019] The phrase "and/or," as used herein in the specification and in the claims, should be understood to mean "either or both" of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases.
Multiple elements listed with "and/or" should be construed in the same fashion, i.e., "one or more" of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the "and/or" clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to "A
and/or B", when used in conjunction with open-ended language such as "comprising" can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A
and B (optionally including other elements); etc.

[0020] As used herein in the specification and in the claims, "or" should be understood to encompass the same meaning as "and/or" as defined above. For example, when separating items in a list, "or" or "and/or" shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items.

[0021] The compounds described herein may contain one or more chiral centers and/or double bonds and therefore, may exist as stereoisomers, such as double-bond isomers (i.e., geometric isomers such as E and Z), enantiomers or diastereomers. The present disclosure includes each of the isolated stereoisomeric forms (such as the enantiomerically pure isomers, the E and Z isomers, and other alternatives for stereoisomers) as well as mixtures of Date Recue/Date Received 2024-03-26 stereoisomers in varying degrees of chiral purity or percentage of E and Z, including racemic mixtures, mixtures of diastereomers, and mixtures of E and Z isomers.

[0022] Accordingly, the compounds described herein encompass all possible enantiomers and stereoisomers thereof including the stereoisomerically pure form (e.g., geometrically pure, enantiomerically pure or diastereomerically pure) and enantiomeric and stereoisomeric mixtures. Enantiomeric and stereoisomeric mixtures can be resolved into their component enantiomers or stereoisomers using separation techniques or chiral synthesis techniques well known to the skilled artisan. The present disclosure includes each of the isolated stereoisomeric forms as well as mixtures of stereoisomers in varying degrees of chiral purity, including racemic mixtures. It also encompasses the various diastereomers.

[0023] When the chemical name does not specify the isomeric form of the compound, it denotes any one of the possible isomeric forms or mixtures of those isomeric forms of the compound. The compounds may also exist in several tautomeric forms.
Accordingly, the compounds depicted herein encompass all possible tautomeric forms thereof.

[0024] The term "tautomer" is generally understood to refer to isomers that change into one another with great ease so that they can exist together in equilibrium; the equilibrium may strongly favor one of the tautomers, depending on stability considerations.
For example, ketone and enol are two tautomeric forms of one compound.

Terpenes

[0035] In some embodiments, a liquid composition provided herein may further comprise a terpene or terpenoid. The term "terpene" is generally understood to include any organic compound derived biosynthetically from units of isoprene (although the term sometimes refers to only isoprene-derived hydrocarbons), and the term "terpenoid"
generally refers to a chemically modified terpene (e.g., by oxidation). As used herein, unless the context clearly dictates otherwise, the term "terpene" refers to both terpene hydrocarbons and terpenoids.
Terpenes may be classified in various ways, such as by how many isoprene units they contain.
For example, suitable terpenes may include monoterpenes, sesquiterpenes, or triterpenes. At least some terpenes are expected to interact with, and potentiate the activity of, cannabinoids, resulting in what is known as the entourage effect.

[0038] In some embodiments, each of the one or more terpenes is a cannabis-derived terpene, i.e., a terpene extracted from a cannabis plant. A liquid composition may have cannabinoids and cannabis-derived terpenes present in specific ratios, which cooperate to provide an entourage effect when vaped.

[0039] In some embodiments, none of the one or more terpenes is a cannabis-derived terpene.
Terpenes may be botanically derived, i.e., extracted from sources other than the cannabis plant, and mixed with cannabinoids in ratios that mimic those present in specific cannabis strains, or in ratios different from those found in naturally occurring cannabis to provide novel flavours.

[0040] In some embodiments, the one or more terpenes comprises at least one cannabis-derived terpene and at least one non-cannabis-derived terpene. Said compositions may provide a combination of the beneficial effects associated with the use of cannabis-derived terpenes or botanically derived terpenes on their own.

[0050] To gain a better understanding of the invention described herein, the following examples are set forth. It should be understood that these examples are for illustrative purposes only. Therefore, they should not limit the scope of this invention in any way.
EXAMPLE

[0051] Crystalline THCA was heated to 110-120 C to effect decarboxylation, yielding a THC oil of at least 90% purity. This THC oil was blended at ¨100 C with a commercial THC distillate oil containing 65-85 wt% THC and commercially available botanical terpenes in a 50:45:5 ratio to obtain a vaporizable composition (Composition A) with a viscosity of about 6000 cP.

Date Recue/Date Received 2024-03-26

[0052] A more viscous comparative vaporizable composition (Composition B) was obtained by blending the THCA-derived THC oil with commercially available botanical terpenes in a 95:5 ratio.

[0053] Both compositions were loaded into commercial CCELL cartridges. When used in electronic vaporization devices, the cartridges containing Composition B had a failure rate of 5-15%. In contrast, the cartridges containing Composition A had a failure rate of less than 5%.

[0054] This example shows that a potent, high-THC composition with viscosity suitable for use in cartridges for electronic vaporization can be obtained by the combination of THCA-derived THC oil, THC distillate oil, and botanical terpenes, and is superior to the combination of THCA-derived THC oil and botanical terpenes without THC distillate oil.
