Dispensaries don’t take credit cards because marijuana is still illegal under federal law, and Visa, Mastercard, American Express, and Discover all block their networks from processing purchases of federally controlled substances. State legalization doesn’t change that. The card networks operate under federal rules, and their internal policies prohibit cannabis transactions regardless of whether the sale is legal where it happens.
Federal Law Is the Root of the Problem
Cannabis is a Schedule I controlled substance under the Controlled Substances Act, grouped with heroin and LSD in the most restrictive federal drug category.1Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances Schedule I drugs are defined as having no currently accepted medical use and a high potential for abuse.2Drug Enforcement Administration. Drug Scheduling That classification hasn’t shifted even as more than two dozen states have legalized recreational use and most states allow medical use.
This mismatch between federal and state law drives everything else. Card networks, banks, and payment processors all answer to federal regulators. None of them get an exemption because a state voted differently.
What the Card Networks Say
Visa, Mastercard, American Express, and Discover each maintain internal policies barring their networks from being used to buy federally illegal substances. These companies operate nationally and internationally under federal regulatory frameworks, and they’ve been clear that state legalization doesn’t move them.
Mastercard put an exclamation point on this in July 2023, sending cease-and-desist letters to payment processors and banks and ordering them to stop allowing cannabis purchases on Mastercard debit cards. The company said it had instructed every financial institution connecting cannabis merchants to its network to end the arrangement. That directive reached beyond credit cards. It also shut down PIN-based debit transactions running over Mastercard’s rails.
Why Banks Won’t Fill the Gap
Even setting the card networks aside, dispensaries struggle to find banks willing to hold their money, which is a prerequisite for accepting any electronic payment. Federal anti-money-laundering statutes make it a crime to knowingly process proceeds from marijuana sales that violate the Controlled Substances Act. A bank employee who knowingly handles dispensary deposits could face up to 20 years in prison under one provision, or 10 years under another, plus civil and criminal fines.3Congressional Research Service. Effect of Rescheduling Marijuana on Access to Financial Services
Some banks and credit unions do serve the industry, but the compliance load is heavy. FinCEN guidance from 2014 requires any financial institution working with a marijuana-related business to file suspicious activity reports every 90 days, run ongoing due diligence, and watch for red flags suggesting the business is diverting product or violating state law.4Financial Crimes Enforcement Network. BSA Expectations Regarding Marijuana-Related Businesses That kind of continuous monitoring makes cannabis accounts expensive and risky. Most banks pass.
What You Can Actually Use to Pay
With credit and standard debit cards off the table, dispensaries have patched together several alternatives. Which ones a given shop offers varies, so check the website before you go.
- Cash is still the dominant option. Most dispensaries keep an ATM on-site for customers who come up short, with fees typically running a few dollars per withdrawal.
- ACH transfers move money directly between bank accounts and don’t touch card networks, which sidesteps the Visa and Mastercard prohibition. Some payment providers offer mobile apps where you link a checking account and pay at the register through an ACH-based system.
- Closed-loop payment apps built specifically for cannabis operate outside the card networks entirely. You load funds or link an account through a dedicated app and pay at participating dispensaries. Reliability and fees vary widely.
- Cashless ATM systems process your debit card as if you were making an ATM withdrawal, rounding up to the nearest increment and giving you the difference as change. Card networks have been cracking down on these arrangements, and their future looks shaky after Mastercard’s 2023 action.
Of the electronic options, ACH-based platforms are currently the most legally defensible. They still require a bank willing to work with the dispensary on the receiving end.
What About Dispensaries That Seem to Take Cards Anyway
If a dispensary appears to run your card like any other retailer, something else is usually happening in the background. Some processors have tried to slip cannabis transactions past network monitoring by miscoding them, assigning a merchant category code for a flower shop, a wellness center, or another innocuous business type. Card networks watch for this. Visa’s Integrity Risk Program tiers high-risk merchants for escalating penalties, and fines for merchant category code violations can reach seven figures when the miscoding has been going on for a while. When a processor gets caught, the merchant loses its account, funds get frozen, the acquiring bank faces penalties, and the processor can be banned from the network. That risk is why serious operators avoid these arrangements, and why the workarounds that pop up tend to disappear.
Will This Change Soon
Two federal changes have dominated the conversation. Neither has landed, and neither would flip the switch on credit card acceptance overnight.
Rescheduling to Schedule III
The DEA proposed a rule in May 2024 to move marijuana from Schedule I to Schedule III. In December 2025, President Trump signed an executive order directing the Attorney General to complete that rescheduling as quickly as federal law allows.5The White House. Increasing Medical Marijuana and Cannabidiol Research As of early 2026, the rulemaking is still open and no final rule has been issued.
Rescheduling would deliver real tax relief to dispensaries under Section 280E, which only applies to businesses dealing in Schedule I or II substances.6Office of the Law Revision Counsel. 26 USC 280E – Expenditures in Connection With the Illegal Sale of Drugs It would not open the door to credit cards. Cannabis would still be a federally controlled substance, and card networks have shown no sign they’ll process purchases of a controlled substance sold outside FDA-approved pharmaceutical channels. FinCEN’s reporting rules for banks would also stay in place.
The SAFER Banking Act
The SAFER Banking Act would give banks and credit unions a safe harbor for serving state-legal cannabis businesses. It has passed the U.S. House seven times in various forms and has never cleared the Senate. Its most recent version is still pending as of 2026.
If it passes, more banks would likely enter the cannabis space, and dispensaries would find it easier to open accounts, run payroll, and access basic financial services. Whether it would immediately unlock credit cards is another question. Card networks could keep their own internal prohibitions in place even after the banking law changes. It is still the proposal most likely to bring near-term relief to the industry’s payment problems.
What to Do at the Register
Bring cash, or check the dispensary’s website for accepted payment methods before you leave home. Many shops have an on-site ATM. A growing number accept ACH-linked platforms or cannabis-specific payment apps. Expect some pricing pressure from the industry’s limited banking access and heavier tax burden, both of which get passed through to what you pay at the counter. Until federal law changes in a meaningful way, or card network policies shift, cash is going to remain the backbone of cannabis retail.
