St. Louis Area Prepares for First 24/7 Drive-Through Cannabis Pickup as Local Rules Evolve

A new round-the-clock, vehicle-oriented cannabis model is arriving in the region

A marijuana dispensary in St. Charles County is preparing to operate around the clock with a drive-up transaction option, a format that would mark the St. Louis region’s first continuously available drive-through-style cannabis pickup. The plan reflects a broader shift in Missouri’s adult-use market toward extended retail access, while also highlighting the role municipal zoning and operating-hour rules play in determining how, and when, cannabis can be sold.

Missouri’s adult-use market expanded quickly after sales began in 2023

Missouri began sales of cannabis for adult, non-medical use on February 3, 2023, after regulators authorized comprehensive licensees to serve customers age 21 and older. Since then, dispensaries across the St. Louis area have expanded footprints, adjusted hours, and added operational features such as curbside pickup and limited drive-through service where local codes allow.

In many municipalities, dispensary operating hours are constrained by local ordinances, even when state licensing authorizes a facility to sell cannabis. As a result, late-night or overnight access depends on local approvals, site plans, and traffic-safety conditions tied to queuing and neighborhood impacts.

Why “24/7” is complicated: local ordinances can be decisive

Across St. Louis County and neighboring municipalities, rules commonly set closing-time limits or restrict sales during overnight hours. Some local codes cap public-facing dispensary sales at 10 p.m. or earlier, while others require conditional-use approvals to extend hours. In the City of St. Louis, policymakers have debated longer operating windows and the potential for drive-through service, with public-safety and traffic-flow issues frequently raised in zoning discussions.

• Operating-hour rules can be set by city or county ordinances and may vary block by block.
• Drive-through or drive-up service often triggers additional conditions related to traffic stacking, lighting, and security.
• Even when a business is open 24/7, specific transaction methods (walk-up window vs. drive-through lane) may have different permitted hours depending on local approvals.

What a 24/7 drive-up model could change for customers and enforcement

A continuously operating drive-up option is expected to appeal to overnight workers and customers seeking shorter wait times during peak hours. It may also create new operational demands: staffing, security, and compliance monitoring across all shifts. For local governments, the model can intensify focus on roadway safety and neighborhood impacts, particularly where queues could spill onto public streets.

Extended-hours retail can increase accessibility, but it also raises more frequent permitting questions about traffic patterns, site security, and compatibility with nearby land uses.

What to watch next

The key determinants for whether 24/7 drive-through cannabis expands beyond a single site will be municipal zoning decisions, public-safety assessments, and how operators demonstrate traffic control and compliance. With Missouri’s adult-use system now established, the next phase for the St. Louis region appears increasingly shaped by local governance: not whether cannabis can be sold, but under what conditions, and at what hours.
