Mastercard recently issued a warning to banks to not process legal purchases of cannabis from dispensaries and online stores. This means the only way to purchase cannabis from many dispensaries is cash-only purchases, making it harder for dispensaries and consumers to get what they need. Mastercard claims that it cannot process these kinds of purchases because cannabis is not federally legal, this shows how important federal legalization or the passing of something like the SAFE banking Act is integral to legal cannabis businesses.
