Legal recreational marijuana dispensaries may generate considerably more economic activity than the sales occurring inside the cannabis store itself. New research examining dispensary openings in Illinois found that surrounding businesses experienced measurable increases in customers, transactions and revenue after recreational cannabis retailers entered their neighborhoods, offering new evidence that dispensaries can function as local commercial anchors rather than isolated specialty stores.
The study examined dispensary openings between 2021 and 2024 and found that businesses located near the new cannabis retailers experienced an average 6.82 percent increase in customers, an 8.01 percent increase in transactions and a 7.47 percent increase in revenue. Researchers concluded that the increase came primarily from dispensaries drawing additional people into commercial areas, creating opportunities for those visitors to make purchases at restaurants, convenience-oriented retailers and other nearby establishments. The findings add an important new dimension to debates over cannabis zoning, because communities weighing whether to approve dispensaries frequently focus on marijuana tax revenue and potential neighborhood concerns while giving less attention to the economic spillovers created for businesses next door.
Illinois Dispensaries Became a Natural Experiment in Local Commerce
The 31-page study, titled “Like a Good Neighbor? Demand Spillovers from Recreational Cannabis Dispensary Openings to Nearby Retail Establishments,” was conducted by Ecem Basak of Baruch College, Aida Sanatizadeh of Northern Illinois University and Kevin Hong of the University of Miami. The researchers combined administrative information on Illinois dispensary openings with monthly economic data showing customer counts, transactions and revenue at surrounding establishments. Illinois provided a useful setting because dispensaries entered different communities at different times, allowing researchers to compare changes near newly opened stores with changes in areas where cannabis retail had not yet arrived.
Rather than simply observing that busy commercial districts happen to contain dispensaries, the researchers used a difference-in-differences design intended to isolate what changed after a cannabis retailer opened. That distinction is important because marijuana businesses often locate in areas that already have strong retail activity, major roads or favorable demographics. By comparing economic activity before and after dispensary openings while accounting for similar businesses elsewhere, the researchers could more closely estimate whether cannabis retailers themselves were generating additional demand in their immediate surroundings.
Nearby Revenue Increased Because More Customers Arrived
The most important finding is that the economic gain appears to come from attracting additional shoppers rather than convincing existing customers to spend substantially more money. Revenue increased 7.47 percent, transactions increased 8.01 percent and customer counts rose 6.82 percent. By contrast, revenue per customer and revenue per transaction changed little. That pattern indicates that dispensaries were expanding the number of people visiting an area rather than changing the spending habits of people who were already shopping there.
Economists often distinguish between growth occurring through the “extensive margin,” meaning more people participate in an activity, and the “intensive margin,” meaning existing participants increase their activity. The Illinois findings point strongly toward the first explanation. A consumer may drive or walk to a neighborhood specifically to visit a dispensary, then purchase lunch, coffee, groceries or another routine item while already in the area. Multiply that behavior across hundreds or thousands of dispensary visits each month and businesses that never sell cannabis can receive a meaningful boost in customer traffic.
Restaurants and Essential Retailers Benefited the Most
The economic spillover was not distributed evenly across every type of neighboring business. Food and beverage establishments showed significant benefits, as did retailers selling essential or routinely purchased goods. Nonessential retail businesses, however, did not experience a statistically significant increase. The difference provides clues about how dispensary visits interact with other shopping behavior.
Stopping at a restaurant, coffee shop, convenience store or grocery-oriented business can easily be added to an existing trip. A cannabis customer who is already away from home can grab food or purchase an everyday item with relatively little additional planning. Buying furniture, expensive electronics, specialty clothing or other discretionary products generally requires a more specific reason to shop. A dispensary can put more potential customers in front of neighboring businesses, but that additional traffic does not guarantee every retailer will convert those visitors into sales.
The finding has important implications for local development planning. Communities sometimes evaluate dispensaries as stand-alone land uses when deciding where cannabis retailers should operate. The Illinois research suggests the surrounding business mix matters considerably. A dispensary placed within a walkable district containing restaurants and everyday retail may generate different economic effects than one isolated inside an industrial zone or surrounded primarily by businesses that depend on planned, high-value purchases.
Walkable Neighborhoods Captured Stronger Spillover Effects
Walkability emerged as another major factor determining whether surrounding businesses benefited. Dispensaries located in more walkable areas produced larger increases in customer traffic, transactions and revenue at nearby establishments. The result is intuitive: when people can easily move between businesses on foot, the cost of turning a dispensary trip into a multi-stop shopping trip becomes extremely small.
The same effect may be weaker in automobile-oriented locations where each additional store requires getting back into a vehicle, navigating another parking lot and making a deliberate decision to stop. A customer driving directly to a dispensary located beside a major roadway may make a purchase and leave immediately. Someone visiting a dispensary on a pedestrian-friendly commercial street may instead walk past cafés, restaurants, convenience stores and other retailers before returning to a vehicle or public transportation.
This suggests the economic influence of cannabis retail is partly an urban-design question. Municipalities interested in maximizing commercial spillovers may have reason to consider pedestrian access, mixed-use zoning and complementary surrounding businesses when deciding where dispensaries can operate. Restricting cannabis stores to isolated areas may reduce neighborhood concerns, but it can also limit the broader economic benefits created by increased visitor traffic.
Weekend Business Saw a Particularly Strong Boost
The researchers also found that positive revenue effects were concentrated more heavily on weekends. That pattern supports the idea that dispensary trips frequently become part of larger recreational or multipurpose outings when consumers have more control over their schedules. A weekday visit may involve traveling directly between work, home and the dispensary. Weekend visitors may combine cannabis shopping with eating out, grocery shopping, entertainment or other errands.
The timing has practical implications for neighboring businesses. Restaurants and retailers located near dispensaries may be able to capitalize on new traffic through weekend staffing, extended hours or promotions aimed at consumers already visiting the district. The study does not suggest businesses should necessarily market themselves specifically to marijuana customers, but it demonstrates that changes in neighborhood foot traffic can have predictable timing that surrounding establishments may notice.
Dispensaries themselves may also become part of a broader destination economy. Cannabis tourism has already developed in several legal states, while local consumers increasingly treat dispensaries like conventional specialty retailers rather than highly unusual destinations. As legal cannabis becomes normalized, its interaction with restaurants, hotels, entertainment venues and other commercial activity may become increasingly similar to the spillover effects created by other destination-oriented stores.
Chain Businesses Captured More Benefits Than Independents
One of the more surprising findings was that positive economic spillovers were concentrated among chain establishments. Independent businesses near dispensaries did not show statistically significant gains overall. Researchers suggested several possible explanations, including stronger brand recognition, standardized products and more developed operating systems that allow chain businesses to capture additional customer traffic more efficiently.
A cannabis customer visiting an unfamiliar neighborhood may recognize a national restaurant, pharmacy or convenience brand immediately and feel comfortable making an unplanned stop. An independent business may require more discovery before the same visitor decides to enter. Chains may also have longer operating hours, stronger online visibility, larger signs, more parking or greater marketing budgets.
That difference complicates the argument that cannabis dispensaries automatically function as engines for small-business development. They can increase the number of potential customers in a commercial district, but independent merchants still have to convert that traffic into purchases. Better signage, local partnerships, pedestrian connections and neighborhood marketing could potentially help smaller businesses benefit more, but the Illinois findings indicate that additional foot traffic alone does not guarantee an equal economic gain for every neighboring operator.
Other Research Suggests Cannabis Can Affect Tourism and Employment
The Illinois findings fit into a growing body of research showing legal marijuana can produce economic effects beyond direct cannabis sales and tax collections. A study of Colorado’s hotel industry by Juncai Jiang, Florian Zach and Norris Bruce found recreational dispensary legalization was associated with an average 25.2 percent increase in hotel revenue, equivalent to roughly $63,671 per month. Researchers attributed the effect to a combination of increased room bookings and higher daily room rates, with stronger effects among hotels located closer to dispensaries and in urban, resort and airport markets.
Labor-market research has also documented positive effects in communities where marijuana stores operate. Economists Avinandan Chakraborty, Jacqueline Doremus and Sarah Stith studied recreational cannabis access in Colorado and found that unemployment fell in counties where dispensaries opened relative to counties without retail access. Employment increased, particularly in manufacturing-related activity, while researchers found no evidence that increased recreational cannabis access caused an overall decline in worker productivity.
Municipal economic analyses provide another perspective. Sacramento has estimated that its cannabis sector supported billions of dollars in total regional economic activity when direct, indirect and induced effects were considered. Cannabis businesses employ workers, purchase professional services, lease commercial property, buy equipment and create additional household spending through employee wages. Retail marijuana therefore behaves like other industries in one fundamental respect: money entering the sector can circulate through the surrounding economy well beyond the original transaction.
Property Values and Commercial Rents Tell a More Complicated Story
The economic effects of dispensaries are not universally positive. Real-estate studies have produced mixed results, illustrating how cannabis retail can create winners and losers even when overall business activity rises. Recent research into commercial property found that retail rents very close to new recreational dispensaries could decline significantly, with estimated reductions of approximately 15 to 29 percent in some locations. The declines became smaller as distance from the dispensary increased.
Residential research has also produced different results depending on location. A 2026 study of medical marijuana dispensaries in Oklahoma found that homes very close to cannabis retailers tended to sell for slightly less, although even the largest estimated effects were below 1 percent of property value. Earlier research using a natural experiment in Washington state estimated that recreational dispensary entry reduced home prices by approximately 3 to 4 percent within about 0.36 miles. A Vancouver study found little overall effect but some evidence of lower prices within 100 meters of dispensaries.
Those findings do not necessarily contradict the new Illinois business study. A dispensary can increase shopping traffic and neighboring revenue while simultaneously creating concerns about congestion, parking, odor, signage or neighborhood image that affect certain property owners. Economic impact is not a single measurement. Commercial sales, property values, tax receipts, employment and residential preferences can all move differently.
Crime Effects May Depend on How Busy the Dispensary Becomes
Public safety is another area where location and customer traffic appear to matter. A 2026 study published in Regional Science and Urban Economics examined medical cannabis dispensaries in Florida and found highly different crime effects depending on dispensary volume and the amount of existing foot traffic in the surrounding area.
High-volume dispensaries were associated with reductions in offenses including larceny, vehicle burglary and motor vehicle theft under certain neighborhood conditions, potentially because additional customers, employees, surveillance and security increased informal monitoring of the area. Low-volume dispensaries located in areas with little existing foot traffic sometimes showed increases in selected property crimes. The researchers concluded that foot traffic is a key variable when assessing how dispensaries influence their surroundings.
That finding complements the Illinois economic research. Cannabis stores are not interchangeable. A busy dispensary in a pedestrian-oriented commercial district may generate a very different neighborhood footprint from a low-volume retailer isolated in a low-traffic area. Local policy that treats every dispensary as producing the same external effects may therefore miss some of the most important variables determining whether a store becomes a community asset or a source of concern.
Local Governments May Need to Rethink Cannabis Zoning
Cannabis zoning debates have historically focused heavily on keeping dispensaries away from schools, parks, residential neighborhoods and other sensitive locations. Many jurisdictions also impose buffer zones between cannabis retailers themselves. Those restrictions were generally created when legal marijuana stores were new and policymakers had little evidence about how dispensaries would affect surrounding communities.
The new Illinois findings suggest overly restrictive zoning could carry an economic cost. If cannabis retailers attract consumers who then patronize nearby businesses, moving dispensaries into isolated industrial districts may prevent commercial neighborhoods from receiving those spillover benefits. That does not mean dispensaries should be permitted everywhere. Communities still have legitimate concerns involving traffic, youth exposure, operating hours, advertising and neighborhood compatibility.
The emerging research instead supports a more nuanced approach. A municipality might evaluate whether a proposed dispensary sits within a walkable shopping district, what businesses surround it, how visitors will arrive and whether the location can accommodate additional customer activity. Cannabis regulation can then move beyond the simple question of whether a dispensary should exist toward the more useful question of where a dispensary can produce the strongest benefits with the fewest negative externalities.
The Illinois Study Still Has Important Limitations
The new research is a preprint and has not yet completed the full peer-review process associated with publication in a major academic journal. It also focuses entirely on Illinois, where cannabis licensing, demographics, transportation patterns and retail geography may differ substantially from states such as California, Colorado, New York or Massachusetts. The size of any spillover effect should therefore not automatically be assumed to apply everywhere.
Observational economic studies also face unavoidable challenges when trying to establish causation. The researchers used a difference-in-differences approach designed to account for many competing explanations, but dispensary locations are not randomly assigned. Cannabis companies seek commercially attractive locations, municipalities impose zoning restrictions and local consumer demand influences where businesses choose to open.
Even with those limitations, the magnitude and consistency of the Illinois findings are noteworthy. Customers, transactions and revenue all moved in the same direction, while the differences across business types, weekends and neighborhood walkability create a coherent explanation for how the effect occurs.
Cannabis Dispensaries May Be Becoming New Retail Anchors
For much of the legalization era, policymakers viewed marijuana stores primarily through two lenses: the cannabis sales occurring inside the building and the taxes governments could collect from those transactions. The newest research suggests the economic footprint can extend farther down the block.
An average 7.47 percent increase in neighboring revenue would be meaningful for many retail businesses, particularly in commercial districts operating on thin profit margins. The fact that the gain appears to come from additional customers rather than increased spending by existing shoppers strengthens the argument that dispensaries can function as localized demand generators. They are bringing people into commercial areas who might not otherwise have visited.
The benefits are clearly conditional. Restaurants and essential retailers gain more than nonessential businesses. Chains appear better positioned than independents. Walkable neighborhoods capture more spillover than automobile-oriented locations, and weekends generate stronger effects than weekdays. Those differences may ultimately be the most useful part of the study.
As recreational marijuana markets mature, cannabis dispensaries are increasingly becoming ordinary components of American retail geography. The Illinois research suggests communities may need to evaluate them the same way they evaluate other high-traffic commercial destinations: not simply by what happens inside the store, but by how the customers it attracts reshape economic activity throughout the surrounding neighborhood.
