Dispensaries are cash only because marijuana is still a Schedule I controlled substance under federal law, and that single fact keeps most banks, all the major credit card networks, and nearly every mainstream payment processor away from cannabis sales. State legalization doesn’t change the federal classification, and the financial system runs on federal rules. So even a fully licensed dispensary paying state taxes on the books usually can’t accept a Visa or Mastercard at the counter.
The Federal Classification Behind It All
Marijuana sits on Schedule I of the Controlled Substances Act, the most restrictive category the federal government uses.1Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances Heroin and LSD share the same schedule. That means every cannabis sale is technically a federal crime, even when the dispensary holds a state license, collects state sales tax, and follows every state rule to the letter.
About 24 states and the District of Columbia allow recreational cannabis sales, and roughly 40 states permit medical use. None of that state-level legality touches the federal classification, and the financial system takes its cues from Washington, not from Denver or Sacramento.
Why Banks Refuse Cannabis Accounts
Banks and credit unions are federally regulated. Taking deposits from a business that sells a Schedule I substance exposes them to potential violations of the Bank Secrecy Act and federal anti-money laundering laws, with penalties that can include heavy fines, loss of charter, or criminal prosecution. Most look at that risk and decide cannabis accounts aren’t worth the trouble.
The Financial Crimes Enforcement Network has published guidance on how a bank can serve cannabis clients legally, but the process is heavy. For every marijuana-related business, the bank must file a Suspicious Activity Report identifying the business, its address, and the fact that the filing exists because the client sells cannabis.2Financial Crimes Enforcement Network. BSA Expectations Regarding Marijuana-Related Businesses Follow-up SARs continue on an ongoing basis, detailing deposits, withdrawals, and transfers since the last filing.
Some banks accept the burden. FinCEN data from the fourth quarter of 2024 shows 507 banks and 182 credit unions actively filing marijuana-related SARs, with over 21,000 such reports in that quarter alone.3Financial Crimes Enforcement Network. Total MRB SARs Received Against roughly 4,500 FDIC-insured banks and nearly 5,000 credit unions nationally, the participating share is small. The institutions that do serve cannabis businesses generally charge much higher fees to cover their compliance costs, which is one reason many smaller dispensaries can’t get accounts even when a willing bank exists in their region.
Why Credit and Debit Cards Don’t Work
A dispensary that manages to open a bank account still can’t run a normal card transaction. Visa and Mastercard operate their own compliance rules, and both prohibit transactions involving products that are illegal under federal law. Visa’s merchant rules bar transactions for products that “claim or imply a similar efficacy as prescription drugs, controlled substances, or recreational/street drugs.” Mastercard prohibits any transaction that isn’t in full compliance with applicable law, which their rules read to include federal law.
This isn’t a gap that clever coding can bridge. In late 2022 the card networks tightened enforcement, and processors that had been quietly routing cannabis transactions through workarounds got shut down. More recently, over 1,000 payment processors were flagged or terminated by sponsoring banks after heightened regulatory scrutiny. As long as federal law treats cannabis as illegal, the major networks stay out.
What Payment Options You Might Actually See
The industry has pushed against the cash-only default for years, and a few workarounds do exist. Availability varies from store to store and can disappear on short notice when a sponsor bank gets nervous.
- Compliant PIN debit. Some dispensaries run point-of-sale terminals that process purchases as PIN-authenticated debit payments through networks separate from Visa and Mastercard credit rails. You swipe or tap a debit card, enter a PIN, and the transaction typically rounds up to the nearest $5 or $10, with the difference returned in cash.
- ACH transfers. Some stores accept Automated Clearing House payments through a third-party app that links to your bank account. It takes a few extra steps at checkout and depends on the dispensary having a processor willing to handle cannabis ACH.
- On-site ATMs. Many dispensaries keep an ATM in the lobby so you can pull cash before you buy. It doesn’t eliminate the cash requirement, but it removes the trip to the bank first. Expect a surcharge of roughly $2.50 to $3.50 per withdrawal.
One option worth flagging because you may have used it before: the “cashless ATM” model, where a debit purchase was disguised on the back end to look like an ATM cash withdrawal. Card networks cracked down on the practice, and it has largely been shut down. Any dispensary still running that workaround is operating on borrowed time.
The common thread across every workaround is that it relies on some financial intermediary agreeing to absorb federal risk. When a sponsor bank pulls out, the payment option vanishes with it, sometimes overnight.
What Could Actually Change This
Two federal changes could meaningfully open banking and card payments for dispensaries: rescheduling marijuana, and passing dedicated banking legislation.
On rescheduling, the Department of Health and Human Services recommended in 2023 that marijuana be moved to Schedule III, a category for drugs with accepted medical uses. The Department of Justice published a proposed rule in May 2024, which drew nearly 43,000 public comments and is awaiting an administrative law hearing.4The White House. Presidential Actions – Increasing Medical Marijuana and Cannabidiol Research A December 2025 executive order directed the Attorney General to complete rescheduling as quickly as federal law allows. As of early 2026, marijuana remains Schedule I. Rescheduling alone wouldn’t fully solve the banking problem, since Schedule III substances are still controlled and banks could stay cautious without an explicit safe harbor, but it would remove one of the biggest reasons federally regulated institutions cite for staying out.
On the legislative side, the SAFE Banking Act would protect banks from federal penalties for serving state-legal cannabis businesses. It has passed the U.S. House seven times with bipartisan support and never cleared the Senate. Its current version, the SAFER Banking Act, remains pending. Until one of these changes takes effect, FinCEN’s guidance and its SAR requirements are the only framework banks have to work with, and most keep deciding the compliance load isn’t worth the business.
What to Do Before You Visit
The practical answer for now is straightforward: bring cash. Some dispensaries offer a PIN debit option or an ACH app, but availability differs by store and can change without warning, so check the dispensary’s website or call ahead before you rely on plastic. If you plan to use the on-site ATM, add the surcharge into what you expect to spend, and pull a little more than you need so a rounded-up debit transaction doesn’t leave you short.
