Yes, if it legal in many states, they should have access to legal and traditional banking services. If cannabis legislation to reclassify the drug has not caught up- so what? Are we going to prevent legal business interests, employee benefits and payroll services from functioning properly because the feds have not caught up- or are encumbered by congressional dinosaurs who have not been in touch with public interests since the epoch when they were first enshrined into their life time positions? It isn’t about the product- it is about operating businesses that are well regulated, beneficial to State and Federal taxation and which provides a widely desired product. I would certainly prefer this to unregulated, un-taxable and unsafe street dealers- just for public safety.
