Age and ID rules at Missouri dispensaries

Straight answer

21 or older, with a valid government photo ID. Any US driver's license, a US passport or a US military ID works, and you don't need a Missouri ID. Expired IDs don't pass. From November 12, 2026, stores can't keep your ID information without your written okay.

ID at the front desk

A valid government photo ID gets you past the front screening area, and this page of our Missouri dispensary guide covers what to bring. The regulator's examples are any US driver's license, a Missouri ID, a US passport book or card and a US military or dependent ID.

Under 21 stays at the front unless they're a patient or with a parent or guardian who is a patient, caregiver or adult shopper, and a store can still say no to kids. In St. Louis, stores post a sign that photo ID showing you're 21 is required.

What the store can keep

The state can't make adult-use shoppers hand over anything beyond an ID that proves age. Patients and caregivers get their state card scanned at every buy.

  • From November 12, 2026. Stores can't create or keep records with an adult-use shopper's identifying information without written consent, can't refuse you for saying no, and face a $500 fine per violation.
  • The tracking system. Every sale is checked against the limits in the state system.

Under 21 and patients

Under 21, holding 3 ounces or less is a civil fine up to $100, or up to 4 hours of drug education instead. Patients can be 18, and a patient under 18 needs written parental consent, with only the parent or guardian caregiver buying for them.

Coming from Kansas, Illinois or farther? buying weed in Missouri from out of state covers your limit and the trip home.
