The State of Cannabis OOH Advertising — 2026

Cannabis advertising in 2026 sits at an intersection of three industry trends. First: the U.S. legal cannabis market grew to approximately $30.1B in 2024 before a slight 2025 decline to roughly $28.6B–$29.6B^[6], with Statista forecasting recovery and continued growth across the rest of the decade. Second: the U.S. out-of-home advertising market hit a record $9.46B in 2025, with the digital sub-segment (DOOH) growing 10.5% YoY to $3.43B^[1]. Third: cannabis brands remain structurally locked out of most mainstream digital platforms, concentrating their ad spend into the compliant channel set that includes DOOH as one of the largest growing components.

This report covers what cannabis OOH actually looks like in 2026 — the market sizing data we can credibly cite, the channel mix cannabis brands actually use, the state-by-state regulatory snapshot that constrains the channel set per market, the vendor and platform landscape (Vistar Media, MediaJel, the bar TV networks, the cannabis-friendly publishers), and the 2026–2030 growth outlook.

Highfloor's view: cannabis OOH is one of the highest-growth advertising sub-segments in the U.S. through the rest of the decade, driven by mature dispensary economics in early-legal states, fresh growth in newly-legal states (Ohio launched adult-use in 2024; Minnesota, Maryland, and others rolling out), and continued maturation of cannabis-eligible programmatic DOOH inventory. The brands that build channel-mix discipline now will outperform the brands that wait for federal rescheduling to unlock Meta and Google.

Industry-wide cannabis advertising spend figures are imperfectly tracked compared to mainstream consumer categories — the structural lockout from major mainstream platforms means much of the spend doesn't pass through Meta or Google's reported pipes, and the compliance complexity makes private-platform-level reporting fragmented.

The most-cited public projection: Statista's North American cannabis advertising spend forecast, which projected growth from approximately $661M in 2018 to $3.89B by 2028 — roughly a 6× increase over the decade^[5]. Actual realized spend in 2024–2025 has tracked the trajectory broadly, though precise public reporting is limited.

Cannabis brands generally spend substantially less on marketing as a percentage of revenue than traditional retail or CPG categories — by some industry estimates 75% less than retail and 80% less than CPG^[6] — but this gap reflects channel-access constraint more than category disinterest. Cannabis brands invest heavily in the channels available to them; the underspend reflects channels that aren't.

The U.S. out-of-home advertising market reached a record $9.46B in 2025, up 3.6% year-over-year, according to OAAA data^[1]. The digital out-of-home (DOOH) sub-segment grew 10.5% YoY to approximately $3.43B (36.3% of total OOH). Q2 2025 alone produced $2.86B in OOH revenue, with DOOH and transit identified as the fastest-growing segments^[2].

Globally, the DOOH market sits at $20.17B in 2025 (Fortune Business Insights estimate)^[7] and is projected to reach $39.12B by 2030 (Grand View Research)^[8] — growth that reflects both the expansion of digital screens replacing static OOH and the growth of programmatic-DOOH (pDOOH) bidding infrastructure.

Cannabis sits inside this growing OOH market as a meaningful and growing buyer category. While cannabis-specific OOH spend share is not separately published in industry-wide data, the directional trend is clearly upward — particularly through cannabis-eligible programmatic SSPs like Vistar Media, which reported major H1 2024 expansion including 68% growth in SSP client base and the addition of cannabis-friendly inventory partnerships including Firefly accepting cannabis ads on car-top digital displays for the first time^[3,10].

Cannabis OOH spend in 2026 distributes across a relatively small set of compliant channels. The categories that aren't on the channel list — broadcast TV in most states, Meta, Google search, TikTok, Snapchat, most major audio platforms — are the categories cannabis brands instinctively reach for first, which is why cannabis channel-mix discipline matters so much.

The strongest cannabis campaigns layer a curated bar TV strategic spine with programmatic display and DOOH for awareness scale, plus rideshare for post-venue conversion in the right markets. Direct mail and in-store signage handle the CRM/retention layer. The channels that are categorically off-limits are off-limits — pretending otherwise wastes time.

Cannabis advertising is regulated at the state level, and the rules vary widely. The audience-composition thresholds, prohibited channels, required disclaimer copy, and venue restrictions all differ. This snapshot covers the 12 highest-volume legal-cannabis advertising states as of 2026; full per-state detail is published at /cannabis-advertising/[state] for all 22 covered states.

The compliance complexity reflected in this table is the single biggest differentiator between cannabis OOH and mainstream consumer OOH. Multi-state cannabis brands need per-state compliance review, state-specific creative variants, and venue auditing per market. Highfloor coordinates this work as part of every cannabis flight in our priority states; brands operating without that infrastructure typically need either dedicated compliance counsel or a managed-service partner that builds it into the buy.

Cannabis OOH and DOOH inventory is delivered through a vendor stack that spans owned venue networks, programmatic SSPs that aggregate venue inventory, cannabis-vertical specialty platforms, and the broader DSP ecosystem.

Programmatic DOOH SSPs. Vistar Media is the largest, with 730,000+ DOOH screens and 120+ media owner partners as of 2024^[3]. Vistar has been particularly active in expanding cannabis-eligible inventory, with a high-profile 2024 case involving Eaze and major media partners (Volta and Firefly) accepting cannabis advertising on their screens for the first time^[10]. Place Exchange, Hivestack, Adomni, and Reverb operate as additional DOOH SSPs with varying cannabis-eligibility tooling.

Cannabis-vertical specialty platforms. MediaJel positions as a "full-stack" AdTech platform purpose-built for regulated programmatic advertising — programmatic display, CTV, DOOH, native, SEO, and Google Ads in compliant categories^[9]. Other cannabis-vertical specialty platforms include Wunderworx, Headi, and a growing set of regional cannabis-specific SSPs and DSPs.

Bar TV networks. Atmosphere TV is the largest mass-market bar TV network with 25,000+ venues. Curated alternatives include Highfloor Media (curated managed-service across 11 Tier 1 + 25 Tier 2 metros), Taiv (5,000+ AI-powered venues), and Social Indoor (3,300+ venues across 20+ states).

Rideshare. Uber Advertising (Journey Ads in-app + JourneyTV in-vehicle tablets), Lyft Media (in-app + Halo Cars car-tops via Firefly partnership), Octopus Interactive (independent in-vehicle tablets), and Vugo cover the major rideshare advertising surfaces. Cannabis acceptance varies by carrier and market.

CTV streamers. Pluto, Roku Channel, Tubi, and certain ad-supported tiers of mainstream services accept cannabis advertising under standard age-gating and compliance review. Major subscription streamers (Netflix with ads, Disney+ with ads) generally do not accept cannabis at scale.

Three trajectories support continued cannabis OOH growth through 2030.

State-level legalization continues. Ohio launched adult-use sales in 2024 and is one of the fastest-growing new markets. Minnesota's adult-use program continues rolling out through 2025–2026. Maryland launched adult-use in 2023. Delaware is in early rollout. Pennsylvania, Florida, and several other states have active legislative or ballot-initiative discussions that could expand the legal-cannabis advertising market further.

Cannabis-eligible DOOH inventory continues to expand. The Vistar Media / Eaze / Firefly partnership in 2024 was emblematic of a broader trend — venue networks that historically declined cannabis advertising are re-evaluating as the legal market matures and as compliance tooling improves. Each new venue network that opens to cannabis advertising expands the total addressable inventory.

Cannabis brand maturation. Multi-state operators (MSOs) have become substantial advertising buyers with sophisticated media-mix optimization. As the cannabis brand category matures into national-feeling brands with consistent identity across markets, the channel-mix sophistication grows in parallel — including increased cannabis OOH spend share.

Headwinds: federal rescheduling discussions continue but haven't produced a usable change to advertising restrictions. State-level regulatory tightening is possible — Massachusetts, New York, and Connecticut all have notably restrictive frameworks that could spread. The cannabis brand consolidation cycle has produced operator failures that remove buyers from the market.

Net trajectory through 2030: substantially up. Statista's $3.89B 2028 North American cannabis ad spend projection^[5] remains directionally credible. The OOH share of that spend should grow proportionally with the broader OOH market's continued expansion.

Cannabis brands building 2026 marketing strategy should organize around the channels that actually work rather than wait for federal rescheduling to unlock Meta and Google. The compliant channel set is good enough — the work is making it work.

Three operating principles for 2026:

1. Lock in a strategic channel spine before optimizing the layers. For most cannabis brands the strategic spine is bar TV (in markets where curated 21+ venue coverage is available) or programmatic DOOH (in markets where direct curation isn't available). Build the spine first; layer programmatic display, CTV, and rideshare against it.

2. Run state-by-state compliance review as a system, not as ad-hoc per-flight work. The audience-composition rules, prohibited channels, required disclaimer copy, and venue restrictions vary state by state. Operators with multi-state campaigns benefit substantially from a managed-service partner or in-house team that handles per-state compliance as a repeatable workflow rather than treating each flight as a one-off problem.

3. Measure attributable lift, not impression CPM. Cannabis advertising's most consistent measurement signal is dispensary foot-traffic lift via geofence-panel data (Placer.ai, Veraset, Foursquare) within a 5-mile radius of conversion points, paired with branded-search and call-volume halo measurement. CPM-on-CPM comparisons against programmatic display systematically undersell curated bar TV's attributed-lift-per-dollar.

The cannabis brand that builds channel-mix discipline now will outperform the brand that's still trying to back-door their way onto Facebook in 2030.

This report synthesizes publicly-available industry data published by trade associations (OAAA), market research firms (Statista, Fortune Business Insights, Grand View Research), industry vendors (Vistar Media, MediaJel), state cannabis regulators (Massachusetts CCC), and trade publications (Marijuana Retail Report, The Drum) as of early 2026.

The report does not include any proprietary Highfloor Media client data. All quantitative figures cite original sources. State-by-state regulatory information reflects publicly-known rule frameworks current as of the audit date; readers should confirm against current state regulator publications before relying on any specific compliance claim.

Highfloor's qualitative assessments throughout the report reflect operator-side perspective drawn from running cannabis flights across our priority markets. Where qualitative claims appear, they are explicitly framed as Highfloor's view rather than industry consensus.
