A dispensary is a state-licensed retail store where adults can legally buy cannabis products under state law. That last phrase does a lot of work. As of mid-2025, 24 states and the District of Columbia allow recreational sales and 40 states permit medical cannabis in some form, yet the federal government still classifies marijuana as a Schedule I controlled substance alongside heroin and LSD.1NCSL. State Medical Cannabis Laws2Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances The federal government has largely declined to prosecute state-legal cannabis operations, but that restraint is enforcement policy, not legal protection, and it shapes nearly everything about how a dispensary looks, what it charges, how you pay, and what risks you carry out the door with your purchase.
Medical and Recreational Dispensaries Are Not the Same Store
States that allow cannabis typically license two kinds of dispensaries, though some permit a single location to serve both markets.
A medical dispensary serves patients who hold a state-issued medical cannabis card or a physician’s recommendation for a qualifying condition. Access is restricted to registered patients and their designated caregivers. Potency limits tend to be higher on the medical side, and purchase limits are often more generous. The real draw is taxes: many states exempt medical cannabis from the special excise taxes imposed on recreational products, and some exempt it from sales tax entirely. The tradeoff is the cost and hassle of getting and renewing a card, which usually involves a doctor’s visit and an annual state registration fee that runs anywhere from nothing to a few hundred dollars.
A recreational (adult-use) dispensary sells to anyone 21 or older with a valid government ID. No card, no qualifying condition. These stores carry the full weight of cannabis-specific taxes. State excise rates on recreational sales run from 6% in Missouri to 37% in Washington, with most states landing in the 10–20% range.3Tax Foundation. Recreational Marijuana Taxes by State, 2025 Add ordinary state and local sales tax on top, and the effective tax on a recreational purchase can easily exceed 25–30%. That gap is why some patients in states with both programs keep their medical cards active even though they could buy recreationally.
What’s Actually on the Menu
The product range at a modern dispensary goes well beyond what most first-time visitors expect. Flower, meaning the dried, trimmed buds you’d recognize, is still the most popular format, sold by weight in eighths of an ounce, quarters, and half-ounces. The rest of the menu usually breaks into a few categories:
- Edibles are gummies, chocolates, beverages, and baked goods that deliver cannabinoids through digestion. Effects can take 30 to 90 minutes to set in and last much longer than inhaled products, which regularly catches new users off guard.
- Concentrates are oils, waxes, and similar extracts with much higher THC content than flower, meant for vaporization. These are not beginner products.
- Topicals are balms, lotions, and patches applied to the skin for localized relief. Most do not produce intoxication.
- Tinctures are liquid extracts taken under the tongue for relatively fast absorption without smoking.
- Accessories cover vaporizers, pipes, rolling papers, and storage containers.
Every product on the shelf has passed mandatory laboratory testing at a state-licensed facility covering potency, pesticide residues, heavy metals, mold, microbial contaminants, residual solvents, and moisture. Products that fail are pulled and destroyed. The label on your package shows THC and CBD content per serving, and that number is tied to actual lab results on a specific batch. This is the layer that separates a dispensary purchase from an unregulated one: you know what’s in it, and you know what isn’t.
What a Visit Looks Like
The first thing that happens at every dispensary is ID verification. A staff member at the door checks your government-issued photo ID to confirm you’re 21 or older, or verifies your medical card at a medical-only location. This is not casual. A single violation can jeopardize the store’s license, so the check is strict and non-negotiable.
Inside, the layout resembles a clean, well-lit retail store. Products sit in secure display cases. You consult with a budtender, the staff member behind the counter, who can walk you through the menu, suggest dosing, and flag interactions you might not have thought about. Quality of guidance varies store to store, so doing a little homework before a first visit is worth the time. You pay at a point-of-sale terminal and leave with your purchase in state-compliant packaging that is typically opaque, child-resistant, and labeled with the testing results.
Purchase Limits
Every state caps how much you can buy per visit or per day. A common recreational limit is one ounce of flower (28 grams), with lower caps on concentrates and on edibles measured in THC milligrams. Some states set different limits for residents and non-residents; Illinois, for example, allows state residents to buy twice as much as out-of-state visitors. These limits are tracked in the store’s system, so trying to hop between dispensaries in the same day to exceed them doesn’t work in states with real-time inventory tracking.
Bring Cash
Here is the part that surprises most first-time buyers: many dispensaries are cash-only or close to it. Because cannabis is federally illegal, banks and credit card companies risk penalties, including money laundering charges or losing their banking licenses, for processing cannabis transactions. The major payment networks won’t touch the industry, which rules out Visa, Mastercard, and often standard debit card processing. Most dispensaries have ATMs on site, but fees add up fast. Some stores have adopted workarounds like app-based bank transfers or cashless ATM systems that round transactions up to the nearest $5 or $10, but these solutions are inconsistent and sometimes shut down without warning. The SAFE Banking Act, which would give financial institutions a legal safe harbor for serving cannabis businesses, has passed the U.S. House seven times but has never cleared the Senate.
Why Prices Are So High
Excise taxes are only part of what you’re paying for. Dispensaries also face a federal tax penalty that reshapes the entire economics of legal cannabis. Section 280E of the Internal Revenue Code prohibits any business that “consists of trafficking in controlled substances” from deducting ordinary business expenses like rent, payroll, utilities, or marketing from gross income.4Office of the Law Revision Counsel. 26 USC 280E – Expenditures in Connection With the Illegal Sale of Drugs Every other legal business in America deducts these costs. Cannabis businesses cannot, because the IRS follows federal scheduling. Effective tax rates can exceed 70% of net income, and that cost is baked into the sticker price at the register.
Federal Rules That Still Apply to You
Even if your purchase is fully legal at the state level, federal law creates consequences most customers never think about. These are the ones worth knowing before you walk in.
Firearms
Federal law prohibits any user of a controlled substance from possessing firearms or ammunition.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Because cannabis is still Schedule I, this applies to every dispensary customer, medical patients included. If you buy a firearm from a licensed dealer, ATF Form 4473 asks whether you are “an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance.” Answering no while holding a medical card or making regular dispensary purchases creates a federal felony risk. Federal courts are currently split on how strictly to enforce this ban and the Supreme Court is considering the issue, but until there’s a definitive ruling, the exposure is real.
Federal Property
Cannabis possession and use are prohibited on all federal property regardless of what state you’re in. That includes national parks, military bases, federal courthouses, post offices, and federally subsidized housing.6National Park Service. Marijuana and Other Substances A purchase that was legal at a dispensary two miles away becomes a federal offense the moment you carry it onto park land.
Crossing State Lines
Transporting cannabis across state lines is a federal crime even if both states have legalized it. The federal government has authority over interstate commerce, and moving a Schedule I substance between states can trigger drug trafficking charges under 21 U.S.C. § 841.7Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A Penalties scale with quantity, but even small amounts create exposure. Flying with cannabis carries the same problem: airports and TSA both operate under federal authority.
Your Job
Federal employees, military personnel, and workers in safety-sensitive positions regulated by the Department of Transportation (truck drivers, pilots, pipeline workers, rail operators) face mandatory drug testing that includes cannabis, and state legalization does not change that. Many private employers also retain the right to test for and terminate employees over cannabis use. A growing number of states have enacted protections for off-duty use, but the protections are inconsistent and often contain exceptions wide enough to swallow the rule. The safest assumption is that your employer’s drug policy governs, not the state’s cannabis law.
Would Rescheduling Change Any of This?
A rescheduling effort is underway. In May 2024, the Department of Justice proposed moving marijuana from Schedule I to Schedule III, and in December 2025, a White House executive order directed the Attorney General to complete that rulemaking “in the most expeditious manner.”8The White House. Increasing Medical Marijuana and Cannabidiol Research As of early 2026, that process remains unfinished.
Schedule III status would likely eliminate the 280E tax penalty, ease banking restrictions by reducing the federal risk to financial institutions, and open pathways for FDA-regulated medical research. What it would not do is legalize recreational cannabis at the federal level. Schedule III substances like ketamine and anabolic steroids are still controlled; they require prescriptions and DEA registration for handlers. Recreational dispensaries would still operate in conflict with federal law, just a less severe category of it. The federal consequences described above, including the firearms prohibition and the ban on federal property, would not disappear with rescheduling. Full federal legalization would require Congress to act, and no such legislation appears close to passing.
