Abstract

The present invention comprises a method of manufacturing a cannabinoid solution including adding to a cannabis source comprising a cannabis distillate or a full spectrum alcohol extracted cannabis oil, adding a PEG, forming a mixture; and adding a PG to the mixture, forming the cannabinoid solution suitable for vaporization and inhalation to administer active cannabis compounds to a person in need thereof.

Claims (12)

1. A method for producing a vaporizable cannabinoid solution comprising:

preparing a solvent extract of a cannabis starting material;

filtering precipitate from the solvent extract;

distilling the solvent extract by heating the solvent extract to generate vapors and condensing the vapors at a vapor temperature in the range of 220° C. to 240° C. under a vacuum in the range of 0.1 TORR to 0.3 TORR to obtain a cannabis distillate containing a cannabinoid;

adding the cannabis distillate to polyethylene glycol (PEG) to form a mixture; and

combining the mixture with propylene glycol (PG) to form the solution.

2. The method of claim 1 , wherein the method further includes adding a flavoring.

3. The method of claim 1 , wherein the method includes adding the PEG in a ratio of 3:1 to 1:1 of the PEG to the cannabinoid, respectively.

4. The method of claim 1 , wherein the method includes adding the PG in a ratio of 200:1 to 1:1 of the PG to the mixture, respectively.

5. The method of claim 1 , wherein the cannabis distillate is substantially free of terpenes.

6. The method of claim 1 , wherein the heating results in decarboxylation, such that the cannabinoid in the cannabis distillate is fully decarboxylated.

7. The method of claim 1 , wherein the cannabinoid in the cannabis distillate is fully converted from tetrahydrocannabinol acid to THC.
