ok, first things first, the legality of what Ohnoyadont said is true. technically and legally, it really is true. HOWEVER, banks closing accounts because your income is from a "Controlled Substance" is BS. They can't do it unless they can prove it in black and white. and they are required to notify you at least 5 business days before the closing of your account. The friend of yours that this happened to may have just had someone at the bank pissed off at them. or someone that was pissed at them may have had influence on the bank employees and had something done. both are very realistic, and more likely than what he's been told, or at least told you he's been told, happened. not bashing anything you've said, im just callin em like i see em.
