Idaho Cannabis Advertising Laws

Idaho has no cannabis advertising framework, because it has no lawful cannabis market. There is no adult-use programme, no medical programme and no licensing authority. Idaho's CBD standard requires zero tetrahydrocannabinol rather than the federal 0.3 percent threshold, so a product lawful under federal law may be a controlled substance in Idaho.

If you are advertising hemp-derived or CBD products here, or targeting Idaho shoppers from a neighboring legal market, our cannabis marketing agency page covers what channels are open.

Marijuana is a Schedule I controlled substance under Idaho Code Title 37, Chapter 27, and may not lawfully be sold in Idaho. Advertising for CBD products containing no THC and derived from the permitted plant parts is governed by Idaho consumer protection law and federal law rather than by any cannabis-specific framework.

Marijuana is a Schedule I controlled substance under Idaho Code Title 37, Chapter 27, the Uniform Controlled Substances Act. There is no adult-use programme, no medical programme, and no licensing framework. Possession of three ounces or less is a misdemeanour; larger amounts and any manufacture or delivery are felonies.

Under Idaho Code §37-2701, a CBD product is lawful in Idaho only where it contains no tetrahydrocannabinol and is derived from specified parts of the plant: mature stalks, fibre produced from the stalks, oil or cake made from the seeds, or sterilised seed incapable of germination. A product at or below the federal 0.3 percent threshold is lawful under federal law and is a controlled substance in Idaho if it contains any detectable THC.

There is no cannabis advertising rule set, because there is no cannabis regulator and no licensed industry.

This page is part of our state-by-state cannabis advertising laws library, covering all 50 states and the District of Columbia.

There is no cannabis advertising rule

Idaho has no cannabis regulator, no licensing authority and no advertising regulations. This is an absence in state law rather than an omission from this page.

Product classification

Under Idaho Code §37-2701, a product is lawful in Idaho only where it contains no THC and is derived from mature stalks, fibre produced from the stalks, oil or cake made from the seeds, or sterilised seed incapable of germination. Idaho's standard is stricter than the federal 0.3 percent threshold, so a certificate of analysis showing compliance with the federal threshold does not establish compliance with Idaho law. The certificate must show no detectable THC.

Business name and licence number

Not required. There is no cannabis licensing framework.

The required warning statements

None. Idaho mandates no warning language in advertising, because there is no cannabis advertising framework.

How the warnings have to appear

Not applicable, as none are required.

When the warnings are not required

Not applicable. There is no disclosure requirement to disapply.

Hotline number

No. Idaho requires no helpline, hotline or poison control number.

Prohibited content

No cannabis-specific content rule exists. What applies instead:

• The Idaho Consumer Protection Act, Idaho Code Title 48, Chapter 6, which prohibits deceptive practices in trade and commerce
• Federal restrictions on disease, treatment and cure claims
• General advertising law

Discounts, coupons, and price promotion

No cannabis-specific restriction exists. General advertising law applies.

Pre-approval

Not applicable. There is no agency with authority to approve cannabis advertising.

What the Law Requires

Idaho states no cannabis advertising age standard, because there is no framework. Idaho has not established a statewide minimum age for CBD purchases.

Audience Percentage Thresholds

Idaho sets no audience composition percentage. This is an absence in state law rather than an omission from this page. Other states do set one: Connecticut requires reliable evidence that at least 90 percent of the audience is 21 or older, and Delaware requires at least 85 percent. Idaho states no equivalent figure for any medium.

Event sponsorship

Idaho sets no audience threshold specific to event sponsorship.

Where the burden sits

Idaho imposes no audience composition evidence or recordkeeping duty for cannabis or hemp advertising. For a regional campaign, the applicable thresholds are those of the other states in the delivery footprint.

Age Gating and Consent

Websites

Idaho prescribes no website age gate and no age verification requirement for cannabis or hemp advertising.

Direct communication

Idaho states no age affirmation requirement for direct or individualized communication.

Location-based devices

Idaho has no location-based device provision.

Established customers

Not applicable. There is no cannabis advertising definition to which an exception would attach.

People Depicted in Ads

Idaho states no casting restriction, no minimum age for persons appearing in advertising, no prohibition on depicting consumption, and no cartoon, mascot or celebrity provision, because there is no cannabis advertising framework.

The Idaho Consumer Protection Act prohibits deceptive practices, and federal law restricts disease, treatment and cure claims, including where implied by imagery.

Restricted Locations and Buffer Distances

Idaho states no cannabis advertising buffer. There is no distance requirement around any facility type, no transit prohibition and no public property prohibition, because there is no cannabis advertising framework. This is an absence in state law rather than an omission from this page.

General outdoor advertising law and municipal sign ordinances apply to physical placement.

The Border

Idaho borders six states. Washington, Oregon, Nevada, Montana and Utah each operate a cannabis programme; Wyoming does not. Marijuana may not lawfully be sold in Idaho, and a product advertised into Idaho may be a controlled substance under Idaho Code Title 37, Chapter 27.

Can You Run a Digital Out of Home Screen in Idaho?

Idaho states no cannabis-specific out of home prohibition. A screen advertising a compliant zero-THC CBD product is subject to general outdoor advertising law and the local sign ordinance. Marijuana may not lawfully be sold in Idaho.

Compliant Use of Geotargeting

• Idaho states no cannabis advertising buffer, so there is no facility exclusion layer required by state law.
• Build Idaho exclusions into campaigns running in Washington, Oregon, Nevada, Montana or Utah for THC products.
• Classify products against Idaho's zero-THC standard at §37-2701 rather than the federal 0.3 percent threshold.
• Check general outdoor advertising law and the municipal sign ordinance for any physical placement.
• For regional campaigns, the applicable audience and content standards are those of the other states in the delivery footprint.

Neither programme exists, so there is no advertising rule set for either.

Recreational. Marijuana is a Schedule I controlled substance. Possession of three ounces or less is a misdemeanour carrying up to one year and a $1,000 fine under Idaho Code §37-2732. Possession above three ounces, and any manufacture or delivery, are felonies. Idaho has not decriminalised possession.

Medical. Idaho has no medical cannabis programme. Legislative proposals have not been enacted. The legislature has advanced measures raising the signature requirements for qualifying a ballot initiative, and has advanced a proposed constitutional amendment to bar legalisation of psychoactive drugs by initiative.

Who regulates hemp here

The Idaho State Department of Agriculture administers hemp production, following 2021 legislation bringing Idaho into the federal hemp framework for cultivation and transport. Idaho was the last state to authorise hemp production.

Non-intoxicating hemp and CBD

Lawful only where the product contains no THC and is derived from mature stalks, fibre produced from the stalks, oil or cake made from the seeds, or sterilised seed incapable of germination, under Idaho Code §37-2701. A product containing any detectable THC, including one compliant with the federal 0.3 percent threshold, is a controlled substance in Idaho.

Intoxicating hemp-derived cannabinoids

Delta-8, THCA, HHC and similar cannabinoids contain THC and are therefore controlled substances under Idaho Code Title 37, Chapter 27. The federal definition of hemp narrows in November 2026; Idaho's zero-THC standard is set by state law and is unaffected by that change.

What it means for advertising

Idaho imposes no cannabis advertising framework, so the state law question is whether the product may lawfully be sold rather than how it may be advertised. A product lawful under the federal threshold may be a controlled substance in Idaho. Classify each product against §37-2701 and hold a certificate of analysis showing no detectable THC before building a media plan that delivers into Idaho.
