Indiana Residents Spend $2 Billion a Year on Cannabis — And the State Spends $20 Million to Stop Them

Indiana has one of the strictest cannabis laws in the Midwest. It also has one of the most expensive — and least effective — cannabis prohibition regimes in the country.

A new economic analysis released this week by NORML finds that Hoosiers spend nearly $2 billion annually on cannabis products. Almost none of that money stays in Indiana. It flows instead to dispensaries in Illinois, Michigan, and Ohio — all of which have legal adult-use markets — or it funds the state’s well-documented illicit trade. At the same time, Indiana state and local governments spend up to $20 million per year enforcing marijuana prohibition: making arrests, processing cases, incarcerating people, and paying for supervision.

The arithmetic is simple, and damning: Indiana is paying tens of millions of dollars annually to keep a $2 billion market underground and out-of-state.

The Billion-Dollar Border Crossing

Indiana is almost entirely surrounded by legal cannabis markets. Illinois opened adult-use sales in January 2020. Michigan followed months later. Ohio launched its recreational program in 2024. Kentucky has a limited medical market. Indiana sits at the center of this ring of liberalization and has, so far, done nothing.

The result is a well-documented phenomenon economists call “cannabis tourism” — Hoosier residents making regular trips across state lines to purchase legally what they cannot buy at home. The NORML analysis doesn’t specify exactly how much of the $2 billion flows out of state versus stays in-state through illicit channels, but anecdotal evidence and sales data from Illinois border dispensaries consistently show Indiana plates in the parking lots. Operators in East St. Louis and the Chicago suburbs have spoken publicly for years about the Indiana customer base that props up their sales volume on weekends.

What Indiana gets in return: zero tax revenue, zero consumer safety standards, zero testing requirements, and zero data on what its residents are actually consuming.

The $20 Million Question

The enforcement side of the ledger is where the analysis gets most uncomfortable for prohibition advocates.

Indiana law still classifies possession of even small amounts of marijuana as a criminal offense. Possession of 30 grams or less is a Class B misdemeanor carrying up to 180 days in jail and a $1,000 fine. Possession with intent to deal can be charged as a Level 6 felony. The state makes thousands of marijuana-related arrests each year — a number that has not meaningfully declined even as neighboring states have legalized.

The NORML report estimates Indiana spends up to $20 million annually on marijuana prohibition enforcement — a figure that includes police time, prosecution costs, court administration, incarceration, and probation supervision. That number is almost certainly conservative. It doesn’t fully account for the downstream costs: lost wages for people with marijuana convictions, reduced employment prospects, housing barriers, and the administrative burden on the courts.

Twenty million dollars is not a catastrophic line item in Indiana’s $22 billion annual budget. But context matters. That’s $20 million that is not being spent on roads, schools, or public health — spent instead on enforcing a policy that demonstrably isn’t stopping anyone from using cannabis.

A Legislature That Hasn’t Moved

Indiana’s general assembly has shown no appetite for reform in recent sessions. No legalization or decriminalization bill has advanced out of committee in the Republican-controlled legislature, and leadership has been explicit about its opposition to following neighboring states toward recreational markets.

The political calculus is familiar. Indiana’s GOP caucus is among the more socially conservative in the Midwest, and cannabis reform doesn’t fit cleanly into the fiscal-conservative framing that might otherwise make the revenue argument compelling. The $20 million enforcement price tag and the $2 billion export of consumer dollars haven’t, so far, been enough to move the needle in the statehouse.

What’s changed this year is the quality of the economic data. Previous estimates of Indiana cannabis spending were rougher and easier to dismiss. A multi-state analysis with firmer consumption modeling and comparable state data gives reform advocates something more concrete to put in front of skeptical legislators — and budget-focused think tanks a reason to weigh in.

The Federal Pressure Layer

Indiana’s prohibition debate doesn’t exist in a vacuum. The 2026 National Drug Control Strategy released by the White House’s Office of National Drug Control Policy last week made marijuana a centerpiece concern — signaling that the Trump administration intends to push back against state-level legalization norms rather than accelerate the federal-state detente that many industry observers had hoped for under rescheduling.

That posture doesn’t directly affect Indiana’s choices. States retain authority to set their own cannabis laws regardless of federal scheduling. But it does complicate the political optics for any Hoosier legislator considering a reform vote. In a state where federal alignment still matters politically, the White House’s hardened position on marijuana gives prohibition advocates fresh rhetorical cover.

The NORML data, on the other hand, cuts through that noise with numbers that are hard to argue with. You can debate the politics of legalization. It’s harder to explain why the state should continue spending $20 million a year to send residents across the Ohio border to buy gummies that are legal everywhere within a two-hour drive.

What Comes Next

The report will almost certainly be deployed by Indiana reform advocates in the lead-up to the 2027 legislative session. NORML and state-based organizations like the Indiana Civil Liberties Union have been pushing incremental reform for years — starting with decriminalization, then medical access — and the economic framing has historically been their strongest argument in a fiscally conservative statehouse.

Whether the numbers move the needle depends partly on what happens in neighboring states over the next 12 months. Ohio’s adult-use rollout has been smoother than many critics predicted. Illinois’s market — now five years old — has generated more than $2 billion in cumulative tax revenue for the state. Every year those programs run without catastrophe is another data point Indiana’s reform advocates can point to.

For now, Hoosiers keep driving to Michigan. And Indiana keeps paying to stop them.
