Programmatic and Alternative Ad Networks for Restricted Categories

Programmatic display now runs almost entirely through automated exchanges: 96.8% of new display ad dollars in 2025 went through those channels, per Persistence Market Research, and cannabis brands, sportsbooks, alcohol companies, and gun retailers mostly can't touch that pipeline. This piece walks through why the lockout happens, who fills the gap, and what an advertiser in a regulated category needs to know before spending a dollar.

Meta bans most dispensary advertising outright. Google's Ad Manager treats cannabis, gambling, and similar categories as restricted or excluded by default, so every piece of inventory is opted out unless a publisher deliberately flips it back on, and TikTok runs roughly the same playbook. This is policy applied at the platform level, and it covers more ground than most people assume: cannabis, alcohol, tobacco and vaping, prescription drugs, gambling and sports betting, firearms and ammunition. Six major verticals, locked out of the default pipeline.

Two different reasons drive this, and the distinction matters for where an advertiser actually has room to move. Cannabis gets excluded largely because of federal legal status in the U.S., a fact platforms can't negotiate around no matter how big the ad budget gets, while alcohol and gambling exclusions are brand-safety calls the platforms made on their own, separate from what federal law requires. Cannabis restrictions work like a wall, while alcohol and gambling restrictions work more like a fence with a gate somewhere, if you know where to look for it.

Restrictions don't stop at platform policy, either. They stack three deep: federal rules from the FTC and FDA, state rules that shift by category and by state line, and platform policy sitting on top of both. A campaign can clear the federal bar, clear the state bar, and still die because a platform decided it doesn't want the risk. Any one of the three layers can shut things down on its own, which is why "we checked with our lawyer" is necessary and nowhere near sufficient.

How the mainstream programmatic stack handles restricted categories, and where the small openings sit

Google Ad Manager's answer is an opt-in system, and it's narrower than the name suggests. Publishers can allow alcohol or gambling and betting ads at the inventory level, but only after opting in at the network level first; for alcohol specifically, only publishers based in what Google calls "Alcohol promotion allowed countries" even qualify. The door exists, but the publisher controls it, and it's a narrow door at that.

Gambling doesn't get that much. There's no network-level setting for gambling or betting inventory in Ad Manager at all, so the permission structure is lopsided depending on which restricted category you're standing in. Alcohol gets a formal, if narrow, opt-in path, while gambling gets nothing comparable.

Cannabis got its own small, cautious opening. Google began allowing some cannabis-related ads in Canada and select U.S. states, though the allowance stays narrow: non-ingestible CBD products, some dispensary services, wrapped in strict disclaimers and geo-fencing. It's real, and it's new as of 2025, but calling it a market opportunity would be generous. It's a crack in the door.

Some mid-market DSPs have gone further than the big platforms. StackAdapt, named among the top mid-market DSPs, allows cannabis advertising, but every advertiser goes through verification first and needs a valid license or permit in whatever jurisdiction they're targeting. Viant's omnichannel DSP takes a different angle for gambling and casino campaigns, with audience targeting built for compliant vertical-specific placements rather than the usual behavioral cookie stack. A handful of general-purpose DSPs have quietly built compliant lanes for specific categories.

Here's the part that trips up a lot of first-time advertisers in these categories: even where the platform technically allows the ad, the compliance work still lands on the advertiser's desk. The platform hands you the key to the room, but the paperwork stays yours.

The tier of purpose-built networks and DSPs built specifically for restricted categories

Below the mainstream stack sits a whole layer of ad networks built for exactly this problem, with purpose-built infrastructure, relationships with endemic publishers, and compliance tooling baked into the platform itself.

Cannabis has the most developed version of this, which makes sense given how completely it's shut out everywhere else. Mantis Ad Network calls itself the largest programmatic platform for cannabis and CBD, with access to more than 250 cannabis-focused publishers, support for display, native, video, and retargeting, and a self-serve model with no monthly minimums. It also runs built-in fraud protection and, in 2025, partnered with PubMatic to extend contextual targeting across a wider set of premium sites. Traffic Roots, based in San Diego, launched back in 2016 with $250,000 in seed funding from Canopy Boulder, making it one of the earlier entrants in cannabis-specific ad tech. Safe-Reach and Cannabx by MNI round out the named options in that space.

Gambling and sports betting have their own specialist lane too, with Viant as a named example on the DSP side, alongside vertical-specific ad tech built to handle geo-compliance and responsible gaming messaging. What ties these networks together, regardless of vertical, is a shared set of structural features: endemic publisher pools whose audiences already sit in-category, built-in age-gating and geo-restriction tools, contextual targeting tuned to content rather than third-party behavioral data, and compliance documentation baked into onboarding instead of bolted on after the fact.

CTV has quietly become a real channel for both cannabis and gambling advertisers, offering adult-audience targeting without the categorical bans hitting social and search. And the broader market data explains why the specialist model fits so well here: over 91% of U.S. programmatic display spend in 2025 flows through private marketplaces and programmatic direct deals, per Persistence Market Research. Specialist networks are basically built for that exact structure, since PMPs are the mechanism through which compliant, endemic inventory gets bought and sold in the first place.

What compliance actually requires from the advertiser, no matter which network they use

Compliance sits with the advertiser, no matter which platform sits in between. Three mechanics show up across every restricted category, and none of them are optional.

Age-gating comes first: ads served only to verified adults, 21 and up for both cannabis and alcohol. The network hands you the tool, but you have to configure it and keep documentation proving you did. Geo-targeting is the second piece, and it behaves less like a one-time setup than an ongoing maintenance job. Cannabis campaigns need state-by-state mapping of where the product is actually legal; gambling campaigns need targeting locked to licensed states only. Neither map holds still, since state law shifts, sometimes quarter to quarter, and a geo-target set once and forgotten is a liability sitting there waiting to happen.

Content restrictions round things out: no health claims for cannabis or supplement products, no messaging that could appeal to minors, no depictions of consumption in a lot of jurisdictions, no pricing promotions in certain categories. These rules bite at the creative level, which is why a lot of networks review ad creative before it ever serves rather than after someone complains about it.

Cannabis specifically requires tracking compliance across three levels at once: federal, state, and platform, according to Cannabis Business Times reporting. A campaign can be clean at two of those levels and still trip the third. The IAB has pointed to exactly this combination as what makes cannabis uniquely hard to advertise responsibly: state laws that keep shifting, advertising guidelines that stay fuzzy, brand safety concerns, and lingering consumer bias against the category. Stack those four together and you get compliance uncertainty even for advertisers doing everything in good faith.

The penalty for cutting corners isn't symmetric, and that's the part worth sitting with for a second. Brands that try to slip past policy using coded language or suggestive imagery risk a permanent account ban, not a warning, not a removed ad. A removed ad costs you a campaign, while a banned account costs you the whole channel, for good. So treat the entire compliance stack, geo data, age verification, creative review, legal sign-off on copy, as infrastructure you maintain continuously, revisited on a schedule rather than run once per campaign.

The gambling and sports betting vertical's distinct advertising dynamics in 2025

Start with scale, because it's large: U.S. sports betting and online gaming spent $3.9 billion on marketing in 2025, according to research published by 5WPR. Television alone soaked up $1.42 billion of that figure, and this is a category with real money behind it.

Yet the digital piece of that spend is shrinking, and that's the part that should catch your attention. Digital ad impressions for online sportsbooks fell nearly 14% in 2025, and sports betting advertising volume has now declined for four straight years, down 1% year-over-year and down 27% from its 2021 peak, per casinobeats.com. Big spend, shrinking digital footprint, and those two facts sitting next to each other are exactly the kind of contradiction that deserves more than a passing glance.

Part of the explanation: a new competitor showed up and started eating impressions. Prediction market platforms have moved into the space and begun competing directly for impressions. Meanwhile compliance is slipping in places you'd expect more scrutiny: compliance gaps in state-mandated responsible gaming messages have drawn growing regulatory scrutiny. That's the kind of gap that draws regulatory attention sooner or later.

A growing number of states have legalized sports betting, and a handful of dominant operators control the majority of total handle between them. That concentration means most programmatic gambling spend runs through a small number of buyers with in-house compliance teams built for exactly this problem. Smaller sportsbooks and regional operators don't have that luxury, so they lean harder on DSPs like Viant, which have already built vertical-specific compliance tooling and audience targeting into the platform, because building it in-house isn't realistic at their scale.

For a sense of where U.S. rules might be headed, UK gambling companies spent £2 billion, roughly $2.62 billion, on advertising in 2024, according to WARC estimates. Comparable scale, but a regulatory environment further along the restriction curve. Worth watching as a preview, not a parallel.

How to size up a specialist network or DSP before you commit budget

Start with the publisher pool, and ask specifically whether it's endemic or run-of-network. Endemic publishers, cannabis media, sports betting news sites, lifestyle content aligned to the category, tend to outperform generic inventory on both compliance and conversion. Ask any network for a representative publisher list and check it against your own brand safety standards before signing anything.

Then look at verification. A network that skips checking for a license or operating permit before onboarding you isn't actually vetting anyone, and that gap becomes your liability, not theirs. Geo-compliance tooling matters just as much. Does the platform keep an up-to-date map of state-level legality, or are you configuring exclusions by hand? Given how often cannabis and gambling law shifts state to state, manual configuration is a risk you're volunteering for.

Targeting method deserves a direct question too. Contextual targeting, meaning content-adjacent placement, works differently from behavioral or audience targeting, and restricted categories often can't lean on behavioral data the way a mainstream retailer can. Find out what data the platform actually relies on, and whether you could defend that method out loud if a regulator asked.

Fraud protection varies more between endemic networks than people expect. Mantis specifically names built-in fraud protection as a feature, which is worth asking about directly with any network you're weighing: what's the invalid traffic filtering methodology, and how is it verified?

Creative review matters for timing as much as compliance. Does the network check your ad creative before it serves, or only after someone complains? Pre-serve review adds a little friction and a little wait, but it cuts your regulatory exposure by a real margin. Reporting is the last piece worth checking: restricted-category advertisers often can't plug into standard third-party measurement vendors, so confirm what attribution method the network actually supports and whether it matches your own reporting needs. And check the access model. Mantis offers self-serve with no monthly minimum, which matters a lot if you're a smaller operator who can't commit to a managed-service floor. That's a real differentiator worth pressing on whenever you're comparing two networks side by side.

Where organic search and owned digital infrastructure cut your dependence on paid programmatic

Underneath all of this sits one structural problem: platform dependency. A policy change at a major DSP or exchange can wipe out a campaign overnight, and there's not much recourse when that happens, which is exactly why diversifying away from paid channels is the practical answer here.

Search is one place that risk doesn't reach. SEO isn't subject to advertising policy at all, so a dispensary, a sportsbook, or an alcohol brand can rank for high-intent search queries no matter what Google Ads permits that quarter. Site performance feeds into this directly: page speed, Core Web Vitals, how easily a site gets crawled, all of it shapes organic rankings. For a business whose paid reach is already capped by category, that kind of technical investment carries more weight than it would for an unrestricted advertiser.

Local search runs especially high-leverage here, particularly for dispensaries and gambling operators tied to a physical location or a state license. Ranking locally in a licensed jurisdiction captures intent-driven traffic that paid channels, hemmed in by geo-restriction and platform policy, can't reliably reach on their own. Content built around category-specific search behavior, strain guides, betting odds explainers, responsible gambling resources, builds topical authority that compounds over time. Organic visibility keeps paying off long after it's built, while paid impressions stop the moment the budget runs dry.

The combination that actually works pairs compliant specialist programmatic networks for top-of-funnel reach and retargeting with SEO and site performance work for capturing high-intent organic demand already searching for you. Treat those as complementary budgets, not competing ones. For businesses in the Midwest operating in regulated categories, dispensaries, tribal gaming operations, licensed alcohol retailers, that combination matters even more, given how wide the resource gap runs between national operators with dedicated compliance teams and local licensed businesses working with a fraction of the budget.
