With cannabis still illegal under federal law, most banks will not work with marijuana companies.

In Massachusetts, the GFA Federal Credit Union is the only company that publicly announced they would deal with recreational marijuana companies.

In California, another state that has legalized recreational marijuana, the industry operates as a mostly-cash economy. That's created all kinds of issues for the business owners and customers.

What does this mean for the burgeoning industry in Mass.?
