I think that a cursory search for banking and cannabis will reveal the pressure the US government puts on this industry. Banking for cannabis is much easier in canada. You can purchase weed with a Visa no problem.

Sure. But OP mentioned the U.S. government "currently blocking transactions" from cannabis businesses.

AFAIK, a bank could lose their FDIC backing (Federal deposit insurance) if they support cannabis transactions.
