## Abstract

A method of producing pure cannabidiol (CBD) isolate crystals including the steps of extracting the CBD compound from a cannabis plant; winterizing to remove fats, waxes and chlorophyll from the CBD extract; filtering the CBD extract through a series of filter plates; removing carboxylic acid and CO2 from the CBD extract; removing impurities from the CBD extract by distillation; and crystallizing the purified CBD extract to produce pure CBD isolate crystals and chopping the pure CBD isolate crystals to produce crystals of between 200 and 600 microns in size. A further embodiment includes the steps of grinding the CBD isolate crystals and salt to produce micro-particles of between 1 and 40 microns and/or macro-particles of between 41 and 100 microns and releasing the particles into an air environment.

## Claims

### Claim 1

A method of producing pure cannabidiol isolate crystals comprising the steps of:
a) extracting cannabidiol from cannabis to produce a cannabidiol extract;
b) removing fats, waxes and chlorophyll from the cannabidiol extract to increase purity of the cannabidiol;
c) filtering the cannabidiol extract to produce filtered cannabidiol extract;
d) heating the cannabidiol extract to produce vapors and remove impurities;
e) condensing the vapors from the heated cannabidiol extract into purified liquid form;
f) collecting the purified liquid form cannabidiol;
g) heating the purified liquid form cannabidiol;
h) cooling the purified liquid form cannabidiol to produce a purified cannabidiol oil mixture;
i) crystallizing the purified cannabidiol oil mixture under cooling to yield pure cannabidiol isolate crystals;
j) rinsing the pure cannabidiol isolate crystals with a solution to remove remaining unwanted impurities;
k) directing the pure cannabidiol isolate crystals through a chopping or cutting device to produce pure cannabidiol isolate crystals of between 200 microns and 1,200 microns in size;
l) miniaturizing the pure cannabidiol isolate crystals to produce particles of pure cannabidiol isolate crystals of between 1 and 100 microns in size;
m) producing particles of pharmaceutical grade salt of between 1 and 100 microns in size; and
n) combining the particles of pure cannabidiol isolate crystals with the particles of pharmaceutical grade salt and releasing the combined mixture into the environment.

### Claim 2 (depends on 1)

The method of claim 1, wherein the particles of pure cannabidiol isolate crystals are present in an amount of between 0.5% and 55% by weight of the combined mixture of pharmaceutical grade salt and pure cannabidiol isolate crystals.

### Claim 3 (depends on 1)

The method of claim 1, wherein the particles of pharmaceutical grade salt are present in an amount of between 45% and 99.5% by weight of the combined mixture of pure cannabidiol isolate crystals and pharmaceutical grade salt.
