Illinois Updates Dispensaries on Higher Possession Limits, Drive-Thru Windows

Possession Limit Jumps to 45 Grams for Adult-Use Consumers

Illinois adult-use consumers can now possess up to 45 grams of flower, up from the previous 30-gram limit, under amendments to the Cannabis Regulation and Tax Act that took effect July 1. The practical read on this change is operational. Dispensaries must update point-of-sale systems, staff training, and compliance protocols to reflect the new ceiling. Medical patients retain their existing 2.5-ounce (70.875-gram) 14-day allotment.

The state's Department of Financial and Professional Regulation (IDFPR) and Department of Commerce and Economic Opportunity (DCEO) used the July 7 briefing to walk licensees through transaction-limit updates and record-keeping requirements. Retailers must log sales to ensure customers don't exceed the 45-gram cap in a single purchase, though cumulative daily possession across multiple stores remains untracked at the state level.

Drive-Thru Service Now Permitted With Local Approval

Dispensaries can now apply to add drive-thru windows, subject to local zoning approval and a facility modification application filed with IDFPR. The rule change, finalized in June, allows licensed retailers to serve customers without requiring them to enter the building. It mirrors accommodations rolled out during the COVID-19 pandemic but is now codified permanently.

Key requirements include:

• Secure product transfer protocols between the dispensary and customer vehicle
• Video surveillance covering the drive-thru lane and transaction window
• Age verification at the point of service (ID check before product handoff)
• Local municipal or county approval via zoning or special-use permit

The drive-thru option isn't automatic. Operators must submit architectural plans, security protocols, and proof of local consent before IDFPR will amend the dispensary license. Processing time for modification applications typically runs 60 to 90 days.

What Operators Need to Do Next

Dispensaries have no grace period on the possession-limit change—compliance was required starting July 1. IDFPR emphasized that any sale exceeding 45 grams to an adult-use customer after that date constitutes a violation subject to fines or license suspension. Medical sales above the 2.5-ounce limit also trigger enforcement action.

For drive-thru service, the timeline is operator-controlled. Retailers interested in the format must first secure local approval, then file a facility modification with IDFPR. No statewide deadline applies. Still, the agency expects a wave of applications from high-traffic suburban locations where drive-thru access offers a competitive edge.
