Is CBD advertising legal?
Hemp-derived CBD became federally legal with the 2018 Farm Bill, provided it contains no more than 0.3% Delta-9 THC by dry weight. That legality is why CBD brands have more advertising options than THC cannabis brands. But legal to sell does not mean unrestricted to advertise: platform policies, the FTC, and state rules all still apply.
The result is a middle lane. CBD is not locked out the way THC is, but it is not a normal consumer category either. Plan for restrictions, especially on claims and on which platforms accept the product type.
The claim problem (FTC)
The biggest CBD advertising risk is not where you run, it is what you say. The FTC has brought enforcement actions against CBD companies for unsubstantiated health claims, and it treats claims that a product treats, cures, or prevents disease as deceptive without rigorous scientific support.
Keep CBD claims to what can be substantiated, avoid disease and condition language entirely, and never imply a medical outcome. This is the same discipline THC advertising requires, and it is enforced harder for CBD because the products are sold more widely.
The ad compliance scanner flags the health and superlative claims that draw FTC and platform attention. Run CBD copy through it before you publish.
LegitScript and platform access
The key that unlocks mainstream search for CBD is LegitScript certification. Google permits topical CBD advertising only from LegitScript-certified advertisers, and several other platforms and payment processors use the same certification as their bar. Ingestible CBD remains rejected on most mainstream platforms even with certification.
If search is part of the plan for a topical CBD line, budget the time and cost for LegitScript certification early; it is the gate, not an optional extra.
The CBD channel mix
For most CBD and hemp brands the working mix is LegitScript-certified search for topicals, programmatic display and DOOH for scale, CTV for high-attention awareness, curated bar TV in the right venues, and owned email and SMS for retention. Influencer and content can work with strict claim discipline and disclosure.
It looks a lot like the THC channel mix with a few more doors open at the top. The brands that scale treat claim compliance as the foundation and build channel reach on top of it.
