How cannabis taxes push prices up and legal sales down

This groundbreaking economic study examines how cannabis taxes affect prices and consumer demand in the U.S. market. Researchers analyzed state-level sales data from January 2014 through June 2023, covering 24 states and D.C. that have legalized recreational cannabis. The findings reveal a clear pattern: a $1 increase in cannabis taxes leads to a $4-$6 increase in consumer prices, meaning taxes are substantially passed on to buyers. More significantly, a 10% increase in cannabis taxes reduces legal sales by 12.6%, demonstrating that consumers are price-sensitive and may turn to illegal markets or simply reduce consumption when prices climb.

The research uncovered an interesting economic relationship suggesting that cigarettes and beer are economic complements to legal cannabis—meaning increases in taxes on these products also reduce cannabis sales. This suggests consumers may view these products as part of a broader leisure or lifestyle category. The study's most sobering finding for policymakers: higher cannabis taxes actually reduce overall tax revenues because the sales reduction outweighs the increased per-unit tax. The researchers discovered that a 10% price increase leads to a 17.8% reduction in sales, indicating demand is quite elastic in the legal cannabis market.

These findings have important implications for policymakers and consumers alike. While taxes can be used to regulate cannabis consumption and generate public revenue, the research suggests there's a critical threshold—push taxes too high, and legal market sales plummet, potentially pushing consumers toward unlicensed dealers or interstate black markets. The study provides evidence-based guidance for states considering cannabis tax policy, suggesting that moderate taxation paired with competitive pricing may be more effective at sustaining both legal market growth and government revenue than aggressive tax increases.
