Cannabis Dispensary Openings Not Linked to Local Crime Increases, Study Finds

Do cannabis dispensaries increase neighborhood crime? A new Canadian study found no statistically significant association between licensed cannabis store openings and nearby crime levels in Toronto and Ottawa.

Armstrong of Brock University, author of the underlying study.

What the Cannabis Dispensary Crime Study Examined

Armstrong’s paper, “Crime levels near federally legal cannabis stores in two Canadian cities,” appeared online in the International Journal of Drug Policy on October 7, 2026.

The analysis covered eight initially licensed stores and police-reported incidents within 3,000 meters of their locations. It examined one category of personal crime and four categories of property crime, using records from January 2018 through February 2020.

That provided 15 months before the stores opened and 11 months afterward. The researcher compared changes across distance bands while accounting for existing trends.

What the Research Found

The analysis identified no significant association between store openings and crime. Although monthly crime counts were somewhat higher after openings, the increase was associated with warmer winter weather and pre-existing trends, rather than proximity to cannabis retailers.

The distinction matters: an increase occurring after a business opens does not, by itself, establish that the business caused it.

How This Fits Into National NORML’s Research Resources

National NORML’s original coverage places the Canadian findings alongside earlier American research.

Its Societal Impacts of Cannabis Dispensaries/Retailers fact sheet collects studies examining neighborhood crime and other community outcomes. The resource includes research finding no significant local crime effect from dispensary openings, as well as studies reporting reductions in some crime measures.

Readers seeking a broader picture should explore National NORML’s references rather than treating any single study as the final answer.

Why This Matters for Florida Cannabis Policy

For Suncoast NORML, the policy lesson is straightforward: claims about neighborhood safety should face the same demand for evidence as any other argument about cannabis.

Residents deserve thoughtful answers about proposed businesses. Local officials should ask specific questions about security, site management, and measurable community impacts. They should also ask whether predictions of increased crime are supported by research.

A public hearing should distinguish a concrete operational concern from an assumption that a cannabis storefront automatically makes a neighborhood dangerous.

We believe responsible oversight and fair treatment can work together. Evaluating a proposed dispensary should involve evidence about the business and its surroundings, with clear standards that officials can explain and communities can assess.

What the Study Does—and Does Not—Establish

These findings concern selected offenses, two Canadian cities, and a defined observation period. They do not establish that every dispensary in every community will have identical outcomes.

Nor does an absence of a statistically significant association prove that an effect is impossible. The appropriate takeaway is narrower: this study did not support the prediction that the openings increased the crimes measured nearby.

Frequently Asked Questions

Does this research mean dispensaries prevent crime?

No. A finding of no significant increase should not be turned into a claim that dispensaries necessarily prevent crime.

How should communities use research like this?

Use it to test assumptions, frame better questions, and inform decisions alongside local evidence. Broad claims deserve careful scrutiny whether they favor or oppose a proposed business.
