The Billion-Dollar Blind Spot
The cannabis tourism market is estimated at $10–17 billion, yet formal economic impact studies are nearly nonexistent at the city level. No tourism board currently tracks cannabis-specific KPIs as part of standard performance reporting, and no city has published a comprehensive cannabis tourism economic impact study.
This represents perhaps the single largest research gap in the cannabis industry — and one of the most valuable opportunities for cities and tourism organizations that choose to measure it.
What the Data Shows
Colorado: The Most Studied Market
A Penn State University study found cannabis legalization drove an immediate $130 million increase in Denver hotel revenues and a 9% jump in occupied hotel rooms in 2014, with effects concentrated in tourist-oriented, lower-priced hotels. A separate Bayesian causal inference study found Colorado hotels averaged 25.2% revenue increases ($63,671 per month per hotel), with hotels closer to dispensaries benefiting more.
Despite this data, Colorado’s Tourism Office historically refused to acknowledge cannabis tourism, with its former director stating: “We still don’t have any numbers that support that marijuana tourism exists.”
Illinois: The Best Cross-Border Data
Illinois is the only state systematically tracking in-state versus out-of-state sales. Out-of-state customers accounted for $385 million (22%) of all adult-use sales in 2024, down from $479 million (31%) in 2022. The decline is attributed to Missouri’s legalization in 2023, which demonstrates a predictable cross-border erosion pattern when neighboring states legalize.
The Illinois cross-border erosion pattern is replicable. When a neighboring state legalizes, out-of-state sales decline 25–40% within 12–18 months. This model can be applied to any border-state market to forecast tourism revenue impact.
Las Vegas: The Struggle
Nevada cannabis sales have declined 17% in taxable revenue since 2021. Consumption lounges — positioned as a major tourist draw — have been a “decided bust”: of 99+ initial applicants, only one state-licensed lounge (Dazed! at Planet 13) remains open. Gaming industry restrictions, the ban on delivery to Strip hotels, and federal banking issues continue to hamper integration with the tourism ecosystem.
Emerging Destination Models
- Visit Oakland created an “Oakland Cannabis Trail” with technology-driven visitor tracking — winning finalist recognition at the U.S. Travel ESTO Awards
- Visit Modesto launched a “CannaPass” gamified passport that drove an 11% traffic boost to local dispensaries
- Destinations International (700+ member destination organizations) has established an official Cannabis & Hemp Task Force
Consumer Demand Data
- 50% of Millennials say legal cannabis access matters when choosing a vacation destination
- 43% have already chosen destinations because cannabis was legal there
- Cannabis tourists spend an estimated $300–400 per dispensary visit on guided tours — roughly 3x the average adult-use consumer
- The MJBiz Factbook estimates a $2.50 economic multiplier for every $1 spent at dispensaries (including hotels, restaurants, transportation, and other tourism spending)
The Missing Infrastructure
Cannabis tourism lacks the basic measurement infrastructure that every other tourism segment takes for granted:
- No city tracks cannabis-specific visitor KPIs
- No standardized methodology for measuring cannabis tourism economic impact
- No cross-city comparison data
- No tourist satisfaction or spending surveys specific to cannabis tourism
- No integration between cannabis purchase data and tourism board visitor tracking
Cannabis tourism is a core focus of our research. The Green Forecast tracks tourism trends quarterly, and our City Reports include localized cannabis tourism assessments for relevant destinations. We are building the measurement infrastructure that doesn’t exist yet.
