Smokeless THC and Administration Method Thereof
A pharmaceutical composition and administration apparatus includes a portable powered vaporizer with a mouthpiece, smokeless vaporizing element, and a removable chamber. The chamber contains a composition comprising tetrahydrocannabinol (THC), cannabidiol (CBD), FCC grade ethanol, flavoring, pharmaceutical grade nicotine, USP grade aqueous glycerine, USP/EP grade propylene glycol, and USP grade vegetable glycerine. In various formulas the THC may be at concentrations of 1-30%, 30-60% and 60-99%, while CBD concentrations may be 0-15% including other cannabinoids derived from extraction.
This application is a divisional application of U.S. patent application Ser. No. 14/167,853, filed Jan. 29, 2015, which claims the benefit of the filing date of provisional application No. 61/849,573, filed on Jan. 30, 2013.
BACKGROUNDMarijuana plant varieties (Cannabis setiva, Cannabis indica, Cannabis rederalis, etc.) contain a variety of compounds, the major psychoactive compound being tetrahydrocannabinol (THC). Other compounds include a variety of additional cannabinoids, including cannabidiol (CBD), which is less psychoactive than THC and believed to have a wider scope of medical applications. Numerous publications report analgesic, antiemetic, and anti-glaucomal effects, among others as resulting from CBD. While typically used recreationally, THC has also been shown to be an effective analgesic, antiemetic, and useful in treating nausea and attendant effects of cancer chemotherapy.
Administration of cannabinoids has evolved over time from the inhalation of marijuana combustion byproducts (i.e., smoking) to oral consumption of marijuana when combined with foods, or the oral consumption of cannabinoid compounds (such as THC and other cannabinoids) in extracted pill form. Additionally, transdermal patches, as discussed in U.S. Pat. No. 6,503,532 have been developed and used in the art. These methods of administration are disfavored however.
When inhaling combustion byproducts, users cannot regulate the percentage of individual cannabinoids entering the lungs. Additionally, undesirable irritating, and potentially toxic or carcinogenic are produced and inhaled as well. The use of orally consumed products such as pills allows users to adjust the quantity of a given cannabinoid ingested, but is disfavored due to the delay of cannabinoid effects caused by the digestive system. Additionally, many marijuana users prefer the mimicry of smoking conferred by inhalation for personal and social reasons. While a transdermal patch may be an effective way of time-releasing a known quantity of particular cannabinoids into the blood stream, this method suffers from drawbacks similar to orally ingested pills, including a lack of social interaction.
For these reasons, there is a need for a cannabinoid composition possessing a predetermined quantity of THC and CBD (in addition to other cannabinoids) for users to obtain a desired recreational, medical or combined effect. There is also a need for an administration technique that allows users to control the quantity of cannabinoids administered through an inhalation apparatus that avoids simple combustion.
SUMMARYPresented is a formulation of cannabinoid and a smokeless administration of use through vaporization in a portable and rechargeable delivery system. The cannabinoids are mixed with several vegetable glycerols including propylene glycol, among other components. Several cannabinoid formulations with varying levels of THC and CBD are contemplated, and preferably will be contained in a cartridge. In this manner, cartridges can be interchangeable with other cartridges depending on a desired effect.
Two embodiments of cartridges are contemplated, a disposable cartridge and a refillable cartridge. In the instance of a refillable cartridge, a syringe may accompany the delivery system for refilling the cartridge. This is due to the high viscosity of high THC/CBD percentage formulations and the attendant difficulty of transferring them from a source vessel into a refillable cartridge.
An improved pharmaceutical composition and administration apparatus is disclosed. The administration apparatus comprising a portable powered vaporizing apparatus having a mouthpiece, a smokeless vaporizing element, and a removable chamber. Portable vaporizers of this variety are typically known as e-cigarettes, which have a heating element for vaporizing nicotine and nicotine-containing oils. In the embodiments disclosed herein, a heating element calibrated for the use cannabinoids is contemplated.
When prepared for use, the chamber contains a cannabinoid composition comprising tetrahydrocannabinol (THC), cannabidiol (CBD), FCC grade ethanol, flavoring, pharmaceutical grade nicotine, USP grade aqueous glycerine, USP/EP grade propylene glycol, and USP grade vegetable glycerine.
Preferably a food grade ethanol and flavoring is used in the composition. Additionally, in one preferred embodiment, the nicotine may include USP grade nicotine extract, and may be extracted from organic sources.
In one preferred embodiment the food grade glycerin will comprise a 99.7% USP Grade Glycerine having 99.70% Glycerol content, 0.3% maximum moisture content, 10 ppm max chlorides, 10 max (APHA) coloring, a minimum specific gravity of 1.2612, 20 ppm max, 5 ppm max heavy metals, 30 ppm max chlorinated compounds, 100 ppm max residue on ignition, 1.000% max fatty acid and esters, 0.5% water, and assayed at between 99.0 to 101.0% (on a dry basis). Additionally the food grade glycerine passes tests for DEG and related compounds and organic volatile impurities. In another embodiment pure vegetable glycerin may be used.
Preferably the propylene glycol selected for usage will be pharmaceutical grade propylene glycol with a specified purity greater than 99.8%, and in compliance with United States Pharmacopeia (USP), European Pharmacopeia (EP), Japanese Pharmacopeia (JP) and Food Chemical Codex (FCC) standards.
Several formulas are contemplated when formulating the pharmaceutical composition. In all cases, where 0% is listed, it is understood that any amount under the maximum percentage down to greater than 0% is intended, including trace amounts. A first formula includes a 30% THC:
A second formula combines known cannabinoids THC and CBD at specific concentrations:
A third formula combines employs a greater percentage of THC along with other known cannabinoids including cannabidiol at a lower percentage, and reduced percentages of acqueous glycerine and propylene glycol:
A fourth formula comprises the higher percentage of THC but with a known quantity of CBD in addition to remaining cannabinoids. As with the previous formula, the acqueous glycerine and propylene glycol are reduced, but in this case including the USP vegetable grade glycerine as well.
A fifth formula comprises the maximum percentage of THC. With this formula, it is intended that either replaceable cartridges or a syringe will be used due to the higher viscosity of the pharmaceutical composition. Additionally, in this formulation, a much reduced quantity of acqueous glycerine, propylene glycol and vegetable glycerine is used:
The sixth formula adds a known quantity of CBD to the high concentration of THC in the formula. Due to the high percentage of THC and CBD, the remaining cannabinoids are reduced as well as the acqueous glycerine, propylene glycol and vegetable glycerine:
In all embodiments it is preferable to have an administration apparatus that is a vaporizer having a mouth piece, a chamber for holding a quantity of the pharmaceutical composition, and a battery powered heating element. A preferable administration apparatus may include an “e-cigarette” type apparatus in which a battery powered heating element is combined with a chamber for holding a preferred cannabinoid formulation. The cannabinoid formulation is drawn from the chamber and heated by the heating element to a vaporization temperature at which point the vapors are inhaled in by a user.
