The short answer — federal scheduling
Cannabis remains a Schedule I controlled substance under the federal Controlled Substances Act. That single fact ripples through every part of the legal cannabis industry’s relationship with the financial system. Banks that hold federal charters or federal deposit insurance face regulatory exposure when they process cannabis-related transactions. Credit-card networks (Visa, Mastercard, Amex, Discover) have a flat policy: no cannabis transactions on the network. Period.
The networks’ policy isn’t about the dispensary’s legality under state law. It’s about federal exposure for the network and the issuing banks. Even a fully state-licensed Washington dispensary in good standing with the LCB cannot accept a Visa or Mastercard at the point of sale.
What this means at the counter
Most Washington dispensaries — including ours — accept cash only. There’s usually an in-store ATM for customers who didn’t plan ahead. The ATM charges its own fee (typically $3-5 per withdrawal), so customers save money by bringing cash from home or hitting their own bank’s ATM beforehand.
A few shops have tried workarounds:
- Cashless ATM — a card transaction structured as an ATM withdrawal that gets paid out as merchandise rather than cash. These look like card payments to the customer. Card networks have been cracking down on them; they tend to be unstable and add $3-4 in fees per transaction.
- PIN debit — debit cards (which use the ATM networks instead of the Visa/Mastercard networks) sometimes work at dispensaries. Less reliable than cash; some banks block dispensary merchant codes.
- Online prepay — a few platforms let customers prepay online and then pick up cash-free. Adoption varies; most customers still default to cash at the counter.
We keep it simple: cash and ATM only. Faster, fewer fees, and the transaction doesn’t fail at the wrong moment.
The banking side
Most Washington dispensaries bank with state-chartered credit unions and community banks that have opted in to serving the industry under FinCEN guidance from 2014. These institutions accept the regulatory burden in exchange for cannabis-industry deposits. They charge higher account fees than ordinary commercial banks (the compliance overhead is real), and the relationship can be precarious — some institutions have exited the space when their compliance costs spiked or when their examiners pushed back.
The lack of standard banking has practical consequences beyond the customer experience. Dispensaries pay employees, taxes, and vendors in larger volumes of cash than equivalently sized businesses in other industries. Tax payments to the state can be made via electronic transfer through the LCB; federal tax payments to the IRS often involve physically depositing cash at a Federal Reserve branch with armored-car transport.
What might change
The SAFER Banking Act and its predecessors have moved through Congress repeatedly but have not passed. The act would create a federal safe harbor for banks and card networks to serve cannabis businesses without federal exposure. If it passes, the card-acceptance landscape would change quickly — most dispensaries would start taking Visa and Mastercard the next quarter.
Until that legislation lands, federal rescheduling could create a similar opening. The DEA proposed moving cannabis from Schedule I to Schedule III in 2024; that process is still working through administrative review and litigation as of 2026. Schedule III would not automatically authorize banking but would substantially reduce the federal exposure that motivates the current restrictions.
Practical guidance
Bring more cash than you think you’ll need. A $50 bill covers most casual visits with room for tax. If you’re shopping for a heavier basket (an ounce of flower runs $100-300 depending on tier), plan accordingly. Round up rather than down; the ATM fee on a single mid-trip withdrawal usually exceeds what you would have left over.
If you’re visiting from out of state, the same federal rules apply nationally — every legal cannabis market in the U.S. runs largely on cash for the same reason.
