Cannabis Taxes Don't Reduce Usage — What This Means for Policy
Advertisement
For years, state lawmakers have justified punishing cannabis tax rates with a simple assumption: higher taxes discourage consumption. It's intuitive logic that appears in policy papers and legislative testimony. But research released by Ohio State University researchers Dexter Ridgway and Jana Hrdinová in early 2026 shatters this comfortable assumption with inconvenient data.
Their findings are stark: there is no meaningful evidence that higher cannabis taxes steer people away from cannabis. In fact, the relationship between tax rates and marijuana use rates is "quite unclear." The implications ripple across the industry, from state legislators facing budget pressures to cannabis business owners gasping under crushing tax burdens.

The Ohio State Study: What the Data Actually Shows
The research examined cannabis tax rates across legal states and cross-referenced them against usage patterns. The results defied conventional wisdom.
The Washington State Paradox
Washington State offers the most striking example. With the highest cannabis tax burden in the nation at 43.5%, you'd expect dramatically lower usage rates. Instead, Washington ranks sixth nationwide in cannabis consumption at 22% of the population.
This isn't anomalous. It's consistent with a broader pattern. High taxes correlate weakly—if at all—with reduced consumption.
The New Jersey Counterpoint
Compare Washington's punishing tax environment with New Jersey, which maintains the lowest state cannabis tax rate at 6.6%. Logically, this should produce the highest usage rates. Instead, New Jersey shows the lowest usage at just 14.4%.
The disconnect is impossible to ignore. A tax rate more than six times lower than Washington's produces lower consumption, not higher. This directly contradicts the deterrence theory underpinning tax policy across the country.
What This Pattern Reveals
The data suggests that consumption patterns depend on factors far more powerful than tax rates: regional culture, demographics, enforcement priorities, and pre-legalization usage patterns. Taxation, by contrast, appears almost tangential to whether people actually use cannabis.
State legislators banking on tax-as-deterrent have misunderstood their leverage. Taxes shape where cannabis is purchased—they don't shape whether it is.
The Unintended Consequence: Pushing People to Black Markets
Here's where the policy failure becomes dangerous. As researchers and industry advocates consistently document, excessive taxation doesn't reduce consumption—it redirects it.
Higher taxes create an economic arbitrage opportunity. Licensed retailers paying 43.5% tax in Washington can't compete on price with illicit dealers operating without regulatory overhead. The consumer choosing between a $15 dispensary gram and a $8 black market gram—all other factors equal—chooses the illicit market.
NORML released an op-ed on March 18, 2026, emphasizing this mechanism. Excessive taxes fuel unregulated markets, defeating the entire purpose of legalization. Legal markets are supposed to displace illegal ones, not coexist in a taxation-driven equilibrium where illicit dealers capture the price-sensitive customer.
The Michigan Case Study
Michigan's experience demonstrates the consequences. The state's 24% wholesale tax—already substantial before retailer markups and local taxes—has crushed the legal industry's competitiveness. Illicit market share has held stubbornly high, undercutting legalization's primary public health argument: removing cannabis from criminal markets.
Licensed retailers can't maintain reasonable margins while paying the wholesale tax, covering operational expenses, and hiring staff. Cultivation operations face impossible economics. The tax tail is wagging the industry dog.
California Recognizes the Problem
Even California, the nation's largest cannabis market, is confronting taxation failure. The state's excise tax—originally intended as a revenue generator and consumption deterrent—has become a stranglehold on the industry.
AB 564, proposed in 2026, would suspend the excise tax rate increase. This represents a significant policy reversal. Even progressive states that championed legalization are admitting that tax rates have exceeded the economic breaking point.
The admission is implicit but clear: we taxed cannabis too aggressively, the strategy isn't working as intended, and we need to recalibrate.
The Revenue Question: Are Taxes Even Generating What They Promise?
Here's the darkly comic part. States justifying high taxes with two arguments—consumption deterrence and revenue generation—are succeeding at neither.
The $25 billion in cannabis tax revenue generated nationally in 2026 sounds impressive until you realize what it represents. States initially projected far higher revenues. The gap between projections and reality reflects underestimated illicit market persistence and overestimated consumer willingness to pay inflated legal prices.
Colorado learned this lesson early. Initial optimism about cannabis tax windfall gave way to reality: taxes must remain competitive with illicit alternatives or legalization fails.
The Circular Logic Problem
States face a trap of their own making. Announce aggressive tax rates to fund education, infrastructure, and social equity [Quick Definition: License programs designed to help communities disproportionately harmed by the war on drugs]. Businesses model their operations around those rates.
Legalization launches. Black market thrives due to price competition. Tax revenue underperforms projections.
Lawmakers, facing budget shortfalls, either raise taxes further (exacerbating the illicit market) or admit the strategy failed.
No jurisdiction has successfully escaped this cycle through higher taxation. Every state discovering this has eventually moved toward lower rates.
What the Tax Foundation Data Tells Us
The Tax Foundation maintains comprehensive state-by-state cannabis tax rate comparisons. Their data shows the wide variance in approaches:
- Washington: 43.5% excise tax plus local taxes
- Colorado: 15% excise tax plus local taxes
- Illinois: 30% retail tax
- California: 15% state excise tax plus local taxes
- New Jersey: 6.6% retail tax
- Vermont: No state excise tax, 6% retail tax
Notably, the lower-tax jurisdictions show more stable legal markets and better illicit market displacement. This inverse relationship—lower taxes correlating with stronger legal markets—represents the opposite of what prohibition-era policymakers assumed.
The Broader Policy Implications
The Ohio State research and supporting data from multiple states suggest several unavoidable conclusions:
First: Taxes Are Not Consumption Controls
Policymakers invoking taxes as demand management tools are relying on discredited economics. Taxation is a revenue tool and a price lever—not a behavioral control lever for this particular product.
If a state genuinely wants to reduce cannabis consumption through policy, that's a legitimate public health goal. But taxation won't accomplish it. Only supply restrictions, age verification, education, and enforcement address actual consumption.
Second: Competitive Rates Matter
Legal markets require pricing that doesn't give black markets an irresistible advantage. This doesn't mean zero taxation—it means thoughtful taxation that captures revenue while maintaining market competitiveness.
Colorado's 15% rate has proven more sustainable than Washington's 43.5%. Not because Coloradans value cannabis less, but because Colorado's policy designers understood basic economics.
Third: The Social Equity Trap
Many states justified high taxes by dedicating revenue to social equity programs—justice system expungements, licensing assistance for communities disproportionately impacted by prohibition, community reinvestment. These programs are vital.
But they're better funded by general revenue or targeted cannabis licensing fees than by crushing tax rates that undermine the legal market they're supposed to serve. A failed legalization system can't fund reparations for prohibition.
Industry Perspectives and Calls for Reform
Licensed cannabis operators are increasingly vocal about tax reform. Trade associations from California to Washington argue that current rates are unsustainable. Small businesses claim they're being regulated out of existence while illicit competitors thrive.
The irony is sharp: legalization was supposed to disadvantage black market dealers by offering transparency, quality control, and legal certainty. Instead, excessive taxation reversed that advantage.
Looking Forward: What States Should Do
If the Ohio State research and multi-state data consensus points toward any policy direction, it's this: states should prioritize competitive legal markets over maximum tax extraction.
This doesn't mean no taxation. Cannabis taxation is legitimate and necessary. But it means rates should be set to maximize legal market share and tax base, not to maximize per-unit tax revenue at the expense of the broader market.
The successful jurisdictions will be those that treat legalization as a market transformation project rather than a revenue maximization exercise. They'll acknowledge that the goal is pulling consumers from illicit to legal markets—not creating a taxation regime so punitive that illicit dealers remain competitive.
The Larger Lesson
The Ohio State study and supporting state-level data deliver a simple but humbling lesson: sometimes our policy assumptions are just wrong. Taxation looked like a elegant tool for simultaneous revenue generation and consumption control. The data suggests it's merely a revenue tool—and not even a particularly effective one when rates exceed market competitiveness thresholds.
The coming years will likely bring tax reform across multiple states. Those that move quickly toward competitive rates will build robust legal markets and strong tax bases. Those that cling to unsustainable rates will continue fighting illicit competitors while underperforming revenue projections.
The choice is becoming clearer. Data-driven policy or dogmatic taxation. The Ohio State researchers have provided the evidence.
Now states must decide whether to listen.
