Indiana residents pour $1.8 billion each year into an underground cannabis market, a new study reveals, despite the state’s tough bans. This huge spend by 1.3 million users, many daily, spotlights lost taxes and enforcement costs. As neighbors cash in on legal sales, Hoosiers fuel a black market that drains the state. Lawmakers now face fresh pressure to rethink old rules.
The RAND Corporation study, out this week, pegs annual cannabis spending at $1.8 billion. That figure could swing from $1.2 billion to $2.6 billion based on survey data. Most cash goes to daily users who buy often.
Frequent users drive the demand. They account for the bulk of purchases, averaging nearly $10 per use day. People get cannabis from illegal sources or cross state lines. Intoxicating hemp products sold in stores add to the total.
This market thrives even as cannabis stays fully banned here. No medical or recreational sales allowed. Indiana misses out on regulating a booming trade right under its nose.
Cannabis Use Climbs Despite Strict Laws
About 1.3 million Hoosiers ages 12 and older used cannabis last year. That’s from the latest National Survey on Drug Use and Health data.
One-third report daily or near-daily use. Past-month users hit 929,000, with 433,000 in that heavy group. Adult use has doubled over the past decade. Past-month rates for those 12 and up jumped from 6 percent to 15.5 percent since 2011.
Youth trends buck the rise. High school seniors’ past-month use fell from 21 percent in 2016 to 11 percent in 2024, per the Indiana Youth Survey.
Use holds steady or grows amid bans.
Enforcement Hits Hard, With Uneven Toll
Indiana logged over 13,000 cannabis arrests in 2024. That covers 12,351 unique people, mostly for small possession amounts.
The state spends $10 million to $20 million yearly on these cases. Black residents face arrests at four times the rate of white residents per capita.
Prohibition chews up taxpayer money while the underground trade rolls on.
Most arrests tie to possession. Many also involve other charges. This system strains courts and jails.
Neighbors Rake In Cannabis Cash Indiana Forfeits
States around Indiana pull in big tax bucks from legal sales. Hoosiers drive over borders, handing money to rivals.
Here’s a quick look at recent hauls:
| State | Annual Tax Revenue (Latest) |
|---|---|
| Illinois | $577 million (2024) |
| Michigan | Over $400 million combined with others (recent months) |
| Ohio | Projected $400 million+ (2026) |
Indiana sits boxed in. Over 40 percent of residents live within 50 miles of a dispensary. Nearly everyone reaches one in 100 miles.
Legal sales could bring $180 million in taxes here within five years. Range sits at $100 million to $270 million. Startup regulation might cost $10 million to $100 million at first.
This shift could cut enforcement bills too. But black markets might linger.
Policy paths vary. Options run from lighter penalties to full adult-use markets run like state liquor stores. Medical cannabis stands as another route.
Gov. Mike Braun signals openness to talk. He notes the surround of legal states. Past pushes stalled, but this study renews the buzz.
As Indiana weighs change, the $1.8 billion black hole looms large. Families feel the pinch from lost schools funds or road fixes. Heavy users risk arrests that scar lives. Yet hope glimmers in tax windfalls and safer products.
