Manufacturing methods, compositions, and medical applications of orally administered cannabis pharmaceuticals using representative/total/complete cannabis extractions (cannabis infused pills)

A method of preparing a decarboxylated cannabis extract, comprising:

• applying an extraction process to cannabis to yield a cannabis extract:
• adding the cannabis extract to a reaction chamber;
• treating the reaction chamber with an inert gas selected from the group consisting of nitrogen, helium, neon and argon;
• in the presence of the inert gas, initiating a decarboxylation process at a temperature of about 90° C. to about 180° C. on the cannabis extract to result in a decarboxylated cannabis extract and byproducts produced from the decarboxylation process;
• condensing, within the reaction chamber by freezing the decarboxylated cannabis extract, and removing byproducts from the reaction chamber;
• retaining, within the reaction chamber, the decarboxylated cannabis extract;
• and
• removing, from the reaction chamber, the decarboxylated cannabis extract.
