Yes, yeast. All this flap about marijuana and Cannabis plant and strain patents and what not. They are passe. The technology is already here to make any cannabinoid, terpenoid and flavonoid that you want in a vat. Just add water, sugar and GMO yeast. Then let it brew and out comes the goods to add to oil for vape pens and pre-rolls, add to beverages, or insert into Rx pills. At a far lower cost. No grow license needed, no plants needed, no sunlight needed, no grand scale grow space needed, no harvest or trimming or extraction processing needed. Just ferment and blend, like wine. Seriously. This is a paradigm buster.
