Ohio Study Links Cannabis Sales to Lower Property Crime

What the Ohio Cannabis Crime Study Actually Measured

Researchers Hunter M. Boehme, Peter Leasure, and Dexter Ridgway examined police-reported crime from January 2023 through December 2025. Their analysis covered 42 law enforcement agencies with usable data and compared 92 census tracts containing dispensaries with 1,386 control tracts. Census tracts are geographic areas commonly used to study neighborhoods.

The key date was August 6, 2024, when Ohio dispensaries began recreational sales. The researchers had 19 months of observations before that transition and 17 months afterward.

Crucially, every dispensary included had already been licensed for medical sales. This was a study of existing medical retailers expanding their customer base, rather than entirely new stores arriving in neighborhoods without dispensaries.

That distinction makes the findings particularly useful for states considering a similar transition. It also limits how confidently they can be applied to new storefronts, different licensing systems, or communities with different security requirements.

Why Comparing Neighborhoods Strengthens the Findings

A simple before-and-after comparison can be misleading. If crime falls throughout a city, a decline near a dispensary does not automatically mean the store helped. If crime rises everywhere, the retailer should not automatically receive the blame.

The Ohio researchers addressed this problem using two approaches called synthetic and conventional difference-in-differences. In accessible terms, they compared changes in dispensary neighborhoods with changes in comparison areas, with the synthetic approach weighting those comparisons to better match earlier conditions.

Both main approaches found reductions in total measured crime and property crime. In the main synthetic model, the property-crime estimate corresponded to roughly 2.8 fewer monthly incidents per 10,000 residents relative to the comparison trend. That is an estimated difference, not a percentage reduction.

Agreement across methods strengthens the overall finding. However, stores were not randomly assigned to neighborhoods, so the analysis cannot eliminate every competing explanation.

Dispensary Security May Be Part of the Opportunity

Cannabis stores can appear attractive to thieves because they hold valuable products and may handle substantial cash. But a potential target can also become a carefully managed property.

The paper discusses Ohio requirements for dispensary security and surveillance, alongside measures such as lighting, barriers, and controlled access. These precautions could help explain why recreational sales did not produce the broad crime increases some observers expected.

There is also a straightforward neighborhood possibility: a well-maintained storefront with staff, customers, and regular activity may create more opportunities to notice suspicious behavior. The researchers discuss increased legitimate foot traffic as another possible explanation.

Neither mechanism was directly established. The useful insight is that the effects of cannabis retail may depend partly on the conditions surrounding it. Cities can help shape those conditions through practical operating standards instead of treating every dispensary as carrying the same risk.

Neighborhood Differences Deserve More Attention

The statewide average was encouraging, but it was not the entire story. Supplementary analyses divided neighborhoods into five groups based on their earlier crime rates. Total crime and property crime generally increased in lower-crime groups, while the two highest-crime groups experienced significant reductions.

Those differences deserve attention without jumping to explanations the study did not test. They do not establish why neighborhoods responded differently. They do show why an overall decline should not become a promise that every community will experience the same benefit.

Murder findings also require care. Some models using incident counts detected an increase, while the main rate models did not find a significant change. The authors caution that murders were infrequent and the finding was inconsistent across specifications.

A constructive response is to keep monitoring specific outcomes. A city can welcome regulated businesses while investigating a troubling local pattern rather than assuming that an encouraging statewide average settles every question.

Canadian Research Adds Useful Perspective

Ohio’s results arrive alongside a recent Canadian study of cannabis stores and crime, published online October 7, 2026. Researcher Michael J. Armstrong examined eight early licensed stores in Toronto and Ottawa and found no significant association between store openings and nearby crime.

That study did not demonstrate the same property-crime reduction reported in Ohio. Instead, it found that observed increases were associated with pre-existing trends and warmer weather, rather than proximity to cannabis stores.

MyCannabis recently explored those findings in its coverage of legal cannabis stores and neighborhood crime. Together, the studies weaken the assumption that licensed retail necessarily brings greater neighborhood crime. Their different findings also reinforce the value of examining each market on its own terms.

How Ohio Communities Can Put the Evidence to Work

The question remains practical as Ohio’s retail network grows. Recent MyCannabis reporting covered Ascend’s seventh Ohio dispensary in October and MariMed’s Columbus dispensary expansion in September. These openings illustrate an evolving market, although they are outside the study’s observation period and should not be treated as evidence of its conclusions.

For local officials, the research supports a more useful discussion about measurable performance. A practical approach could include:

• Setting clear expectations for lighting, access control, and security.
• Tracking neighborhood crime alongside suitable comparison areas.
• Reviewing results regularly and responding to specific problems.

These are policy implications, rather than interventions the researchers tested. Their advantage is accountability: residents gain a way to evaluate outcomes, and responsible operators gain an opportunity to demonstrate that they can be constructive neighbors.

There is also a timing lesson. Ohio’s October 2026 cannabis market update describes a retail system that has continued developing since the research period ended. Future evaluations should distinguish established medical stores adding recreational sales from newly opened businesses. Combining those experiences too quickly could hide which operating models work best.

Public safety is also broader than the offenses measured here. Traffic safety, youth access, and consumer health require their own evidence. Keeping those questions separate makes the positive crime findings more useful because each policy claim can be judged against the outcomes actually studied.

A Stronger Foundation for Cannabis Retail Decisions

The Ohio study leaves several questions open. Police records cannot capture every incident, four agencies were excluded because of incomplete data, and neighborhood-wide results may miss changes on particular streets. The study’s total-crime measure also excluded rape and arson, so it should not be described as covering every serious offense.

Longer follow-up could reveal different patterns. Yet those limits do not erase the central finding: expanding recreational sales at existing medical dispensaries was associated with lower property crime overall, without a consistent increase in overall violent crime.

For communities weighing cannabis retail, that is a meaningful opening. Evidence supports moving beyond an automatic expectation of harm toward clear standards, careful monitoring, and a willingness to recognize when regulated businesses coexist successfully with neighborhood safety.
