Cannabis companies couldnt do "real banking" do to federal shenanigans.

So instead why dispensaries would do, is make another LLC who buys the building and all the building permits that are municipally regulated - then as the municipality zoned and approved locations and projects for dispensaries and distribution licenses (which had a multitude of their own specific restrictions)

They would then rent the facilities for ridiculous rental amounts which the rental company would legally be able to put into any regular bank - then make loans to the cannabis companies and dispensaries for whatever operating expenses were needed.

This got really ugly when Med Men, based out of LA, was made really public because of douchebaggery happening in the company revealing how they had been gaming their own investors etc...
