How Does Metrc Age Verification Work
Learn how Metrc ensures age verification for cannabis purchases online.
Do dispensaries allow visitors under 21 inside?
No. In every U.S. state with legal adult-use cannabis, a dispensary must confirm that each person on the sales floor is 21 or older, and that rule covers visitors and out-of-state guests the same as residents. A tourist with a passport gets the same answer as a 19-year-old neighbor: no valid ID showing 21+ means no entry.

The common exception is medical. Adults 18 to 20 with a valid state medical card can shop at a medical dispensary in most states that run a patient program. Anyone younger needs a registered caregiver in the states that allow one.
Why does the age check apply to visitors, not just buyers?
Age limits come from state law, not store preference. A licensed shop that lets an underage person past the door risks fines, suspension, or loss of its license, so the entrance check is a compliance step rather than a courtesy.

Staff face charges as well. In most legal states, selling or handing cannabis to someone under 21 is a criminal offense for the employee, not only for the business.

That is why shops check twice: once at the door and once at the register. Many scan the ID, and an expired, damaged, or fake document ends the visit at the entrance.
Are there exceptions for anyone under 21?
Yes, and most of them are medical.
- Patients 18 and older: a state-issued medical cannabis card lets an 18-, 19-, or 20-year-old enter a medical dispensary in most states with a patient program. Some states also require a state ID that matches the card.
- Patients under 18: many states allow minors with a qualifying condition, but the visit runs through a parent or legal guardian who registers as a caregiver. The minor stays with that adult the whole time.
- Caregivers: a registered caregiver can buy on a patient's behalf. The caregiver must meet the state age minimum, and the product goes to that patient only.
- Adult-use shoppers: no exception exists. A 20-year-old with no medical card cannot enter or buy in any adult-use state.
Can a 19-year-old buy weed in a legal state?
Not from a licensed adult-use store. Every state with legal adult-use sales sets the minimum at 21, and no state offers a visitor pass, a tourist exemption, or a parent permission slip for the adult-use side.
The only route is medical: get a card in the state where you live (or, in a few states, use an out-of-state card) and shop at a medical dispensary that accepts patients. That path takes a doctor's approval and a state registration, not a walk-in.
What ID counts at a dispensary?
Shops accept government-issued photo ID that shows your date of birth. Bring the original, not a photo on your phone.
- State driver's license or state ID card
- U.S. passport or foreign passport
- Military ID
- Tribal ID, where the state recognizes it
Expired documents get refused in most shops, and so do paper temporary licenses without a photo in some states. If your license is vertical (the under-21 format in many states), expect a closer look and a second check at the register.
Out-of-state IDs work for adult-use purchases in states that let visitors buy. Medical cards are a different story: most states require residency, and only a few accept a card issued elsewhere.
Can someone under 21 wait in the lobby or the car?
It depends on the shop and the state. Some dispensaries let a minor sit in a waiting room with a 21+ adult, and some bar the door to anyone who cannot show ID. There is no national rule to lean on here.
Call the store before you drive over. Ask one question: "Can a 19-year-old wait inside while I shop?" The answer takes ten seconds and saves a wasted trip.
No shop allows an underage visitor to touch product, sample anything, or stand at the register during a sale. Those are license violations.
What happens to a store that sells to someone under 21?
The penalties are steep, and they land on the business and the employee. States impose fines, suspend or revoke licenses, and in some cases bring criminal charges. Regulators also run compliance checks with underage buyers posing as customers.
A budtender who misses a fake ID can lose their job and face charges in the same case. That reality explains the strict door policy that visitors find annoying.
Do delivery and online orders follow the same age rules?
Yes. A delivery driver checks ID at the door, and the order goes back to the store if the person receiving it cannot prove they are 21+ (or 18+ with a valid medical card on medical deliveries).
Ordering on someone else's behalf does not work either. Placing an order for a person under 21 is against the law in legal states, and the account holder takes the risk, not just the minor.
Can a parent buy cannabis for their under-21 child?
No, with one narrow medical exception. Handing cannabis to a minor is against the law in every legal state, and a parent who does it can face charges.
The exception is a registered minor patient program. In states that allow it, a parent registers as the caregiver, buys within the patient's limits, and keeps the product under their control.
Frequently asked questions
Can I bring my child into a dispensary?
It depends on state law and store policy. Some states ban minors from the sales floor outright, while others allow a minor in a waiting area with a guardian. Ask the shop first.
Do dispensaries accept expired IDs?
Almost never. An expired document does not prove current age or identity, and regulators treat it as a compliance failure. Renew before you go.
Is the age limit different in medical states?
Yes. Medical programs often set 18 as the patient minimum, while adult-use sales stay at 21. A patient card from one state rarely works in another.
Can a 20-year-old enter a dispensary with a parent?
Not to shop. Having a 21+ adult beside you does not override the age limit for adult-use sales. The pair can be turned away at the door.
