## Abstract

The invention is methodology of producing a variety of cannabis derivatives such as THC, CBD, Delta-11, and budder. The technique involves the steps of: grinding a whole cannabis plant, including the root ball thereof, freezing the ground plant, soaking the frozen ground plant in a selected solvent, and, removing the solvent, thereby producing desired derivative of cannabis. Solvents include coconut oil, olive oil, vegetable oils, avocado oil, and seed oils.

## Claims

### Claim 1

A method of producing a refined delta-11 in cannabis consisting essentially of:
a) grinding a cannabis plant chosen for its delta-11 levels;
b) freezing the ground cannabis;
c) soaking the frozen ground cannabis in a solvent;
d) simultaneously applying pressure greater than 15 pounds per square inch and heating the frozen ground cannabis in the coconut oil in the range of 190-265 degrees F. for a period of between 45 minutes and 3 hours, thereby yielding a delta-11 cannabis budder; and,
e) passing the delta-rich cannabis budder through a mesh screen to remove cannabis plant parts, thereby producing the refined delta-11 cannabis.

### Claim 2 (depends on 1)

The method of producing a refined delta-11 in cannabis according to claim 1, further including the step of choosing the solvent for soaking the frozen cannabis from the group consisting of coconut oil, olive oil, vegetable oils, avocado oil, and seed oils.

### Claim 3 (depends on 2)

The method of producing a refined delta-11 in cannabis according to claim 2, wherein the step of passing the delta-rich cannabis budder through a mesh screen to remove plant parts includes selecting a mesh screen having a mesh size of 160-220 microns.

### Claim 4 (depends on 2)

The method of producing a refined delta-11 in cannabis according to claim 2, wherein the step of freezing the ground cannabis plant includes the step of applying carbon dioxide to the ground cannabis.

### Claim 5 (depends on 2)

The method of producing a refined delta-11 in cannabis according to claim 2, wherein the step of grinding the cannabis plant comprises the step of grinding the root ball of the cannabis plant.
