Illinois: Cannabis Consumption Rises As State Tax Revenue Dips

Oct 15, 2026 | Great Lakes Region, Illinois, Sales

Illinois’ cannabis industry saw a big drop in sales numbers over the last year, but it’s not because demand or product sales dropped, a new state report shows.

According to the report released by the Illinois Department of Financial and Professional Regulation’s Cannabis Regulation and Oversight Office, total dispensary sales dropped to about $1.5 billion in fiscal year 2026.

That’s down from nearly $2 billion in sales in 2025.

But that downward financial shift came despite an uptick in demand. Monthly sales figures show more than 5 million adult-use cannabis items sold in July, marking a record high. August sales totaled nearly 4.9 million adult-use items, a 9% increase in items sold compared to last year.
