Every state that allows adult-use cannabis sales sets the minimum purchase age at 21. Medical programs set 18 in most states. Some states let a patient under 18 buy medical cannabis if a parent or caregiver registers with the program. Federal law sets no cannabis purchase age because federal law bans sale. The state license holds the rule that a dispensary follows.

Who must show ID
Staff check ID for every customer who buys, and in many states for every customer who enters the sales floor. The check repeats at delivery, at curbside handoff, and at pickup. A store that skips the check on a repeat customer still holds the violation.
Adult-use and medical age limits
- Adult-use retail: 21 in every state with legal sales. No exceptions for medical card holders on the adult-use side.
- Medical: 18 in most programs, with a state card or a physician recommendation.
- Patients under 18: allowed in some states with a registered parent or caregiver who buys on the patient's behalf.
IDs that pass a check
- State driver license or state ID card, unexpired
- US passport or passport card
- Military ID
- Tribal ID, accepted in some states
- Foreign passport, accepted in some states, sometimes with a second document
Expired IDs fail in most states. A vertical driver license marks a holder under 21, and many stores run a second scan or a manager check on those. Out-of-state IDs work for adult-use purchases. A medical purchase needs a card or recommendation from that state, not another one.

Where the check happens
- Door or lobby, before entry to the sales floor
- Point of sale, before payment
- Delivery, at the door, with a signature
- Curbside or pickup window, at handoff
How stores verify
Most point-of-sale systems scan the PDF417 barcode on the back of a US license. The scan reads name, birth date, and license status. Software from vendors such as IDScan.net, Veratad, and Yoti links to the POS. A failed scan sends the sale to a manual check. Staff note refusals in the POS log, and state inspectors read those logs during a compliance visit.

Penalties
A sale to a minor can lead to a fine, a license suspension, or a license revocation. The penalty depends on the state and on the number of prior violations. Some states charge the employee who made the sale with a misdemeanor. Regulators run compliance checks with underage buyers who work with state agents.
State examples
- Colorado: 21 for retail, 18 for medical patients
- California: 21 for retail, 18 with a physician recommendation
- New York: 21 for retail, 18 for medical patients
- Florida: 18 for medical patients, minors with a caregiver
- Oklahoma: 18 for medical patients
These examples cover the age threshold. ID types, scan rules, and delivery checks sit in separate statute sections and differ from state to state.
Delivery and curbside
Delivery adds a second check. The driver scans the ID at the door and collects a signature. Some states require the driver to match the ID name to the order name. A mismatch cancels the delivery. Curbside orders follow the same rule at handoff, even when the customer paid online.
What to confirm with the state
Age limits, accepted ID types, and scan requirements live in state statute and in the regulator's rules. Check the state cannabis regulator for the current list before a store opens or changes its intake process. Rules change with each legislative session and each rulemaking cycle.
