Buying weed in Missouri from out of state

Straight answer

Yes. Anyone 21+ with a valid photo ID can buy here at the same 3 ounce limit as locals, and you don't need a Missouri ID. Stores may honor a medical card from home. It can't leave the state, not even across the river into Illinois, where it's legal too.

Buying as a visitor

Visitors shop the same 226 licensed stores as locals, and this page of our Missouri dispensary guide covers what changes for you. Mostly, nothing does. The rules define an adult-use buyer by age alone, with no residency rule, so you get the full limit.

Any US driver's license works. Stores may accept an equivalent medical card from another state but don't have to, and since the card has no residency rule, visitors can even get a Missouri card through a Missouri clinician. The caps are in our Missouri purchase limits tool.

Illinois is legal. The river still counts.

St. Louis sits on the Illinois line, where visitors can carry 30 grams of flower and residents 60. That doesn't make the trip legal. Crossing a state line with cannabis breaks federal law, and Illinois wants it in a sealed, odor-proof, child-resistant container out of reach.

Kansas City is the other edge, with Kansas right across State Line Road and no legal market. Using it here is the other half, and where you can smoke weed in Missouri maps every spot.

Airports and the federal line

TSA doesn't search for drugs, but it hands any illegal drug it finds to police. Its medical marijuana page now reads "Yes (Special Instructions)" without giving any, and that's no permission slip. We haven't found an airport policy from STL or MCI, and airport grounds are public places.

An April 28, 2026 rule moved state-licensed medical marijuana to Schedule III. Adult-use stayed Schedule I, and nothing in it makes carrying it between states legal. How every other state treats visitors is in our can tourists buy weed guide.

Can tourists shop at Missouri dispensaries?

Yes. Anyone 21 or older with a valid government photo ID can buy, resident or not.

Is the limit lower for visitors here?

No. Visitors get the same 3 ounces per transaction as residents.

Will a dispensary here take my home state's medical card?

Maybe. Stores may accept an equivalent card from another state, but they don't have to.

Can I drive weed from St. Louis into Illinois?

No. Illinois is legal too, but carrying cannabis across a state line breaks federal law. Buy there instead.

Is rec legal in Branson?

Yes, at licensed stores for anyone 21+. Table Rock Lake's shoreline is federal land, though, where it's still illegal.
