Missouri adult-use access
Missouri Department of Health and Senior Services (DHSS) says adult-use marijuana may be purchased by individuals 21 and older. Legal sales are limited to dispensaries licensed by DHSS; the state describes acceptable government photo identification. See Missouri's current general FAQ.

The adult consumer possession cap
DHSS says consumers may possess up to 3 ounces at any time. This is not the same as the medical program's purchase or possession amounts, and DHSS cautions that patient and consumer limits should not be combined to exceed the applicable amount. Check your status before relying on a medical allowance.
Licensed sales and scope boundaries
DHSS says legal medical and adult-use sales are allowed only at a department-licensed dispensary. This Missouri summary does not decide whether a particular place, trip, or product is permitted under other state or federal law. Consult the official rules that apply to your location. See U.S. state/federal overview.
