If that is polarized hash, the book says there is 1 more step you can do to make like REAL REAL Medical grade stuff.
Next time whoever made that hash (if it is polarized) makes it, tell them that at the end, when it is in the solvent. Add a few drops of Sulfuric acid, and it will Isomerize ALL the Cannabinoids, turning all of them into THC Cannabinoids (all the CBD and CBN and stuff) then at the same time it is supposed to turn all the THC Cannabinoids into JUST Delta-9-THC. This would make it REAL Medical, like Clinical grade, ready to be sent out to hospitals.
And baking soda or lye to deactivate the acid before smoking.
Oh Fin. Sir Shagmeister.
Herr Doktor Flossenzottig, I must confess and bare the very depths of my fail to you. My sense of honor and duty to my illustrious alma mater, the exalted Central Joisey Community College, demands it.
Y'see, I have been testing one of the principles that you in your selfless pursuit of spreading the hempish Gospel have presented to us here.
Some time ago, I set a batch of a CBD-rich extract to digest with a fractional drop of sulfuric acid in doubly-distilled ethanol. Nothing happened. Then I upped the acid to three entire quaking drops and refluxed the mixture.
The Beam's test went from quite positive to negative. The CBD was converted.
So last night I smoke-tested my new Flossenzottig Medical Grade Extract. I got muy muy stoned.
Truly I must publicly right the wrong i have done you. You, Herr Doktor, had it right. I hope that you will accept this abject apologia from one of your first and most steadfast fans on Riu. I salute you, Cannabis Warrior.
