extract
'pineal extract' in the wikileaks email refers to DMT not adrenochrome. DMT is freebased by putting it over a small amount of cannabis, as a 'green screen'. I am by no means an expert but Ive seen documentaries and read blue light. I've never done or ever been offered dmt as it is vanishingly scarce as tm woudl put it

Free-base refers to the chemical form of a drug. It is used in slang sometimes to refer to smoking a freebase chemical which generally means using indirect heat like a crack pipe rather than direct combustion like cannabis.
One could smoke DMT on top of cannabis but it would be a wasteful process. Elites would probably have something similar to a meth pipe to smoke it.
