Idaho
cannabis & CBD market

Idaho is a full prohibition state: no medical program, no adult-use market. Since July 1, 2026, HB 879 ties retail hemp products for ingestion or inhalation to Idaho's 0.3 percent total THC definition, while ISDA guidance still states 0 percent at distribution. The legal retail segment is CBD, hemp, smoke and vape shops.

The law, as it stands

Idaho status board

Legal status
Full prohibition. No adult-use market and no medical cannabis program. Marijuana and tetrahydrocannabinols are Schedule I substances under Idaho Code 37-2705, and possession, delivery and manufacture are criminalized under Idaho Code 37-2732.1
What may be sold at retail
Hemp derived CBD, and other hemp products only if they meet Idaho's hemp definition. Idaho Code 22-1705(4) ties retail products for ingestion or inhalation to the criteria in 37-2701(u), while ISDA guidance still states 0 percent THC at distribution. High THCA flower fails the total THC test, and delta-8 remains exposed under Idaho's Schedule I tetrahydrocannabinols listing.1
Governing body
The Idaho State Department of Agriculture regulates hemp. Idaho Code 22-1705(4) now places establishments offering ingestible or inhalable hemp products under Title 22, Chapter 17, and 22-1705(5) authorizes ISDA to set fees and penalties by rule. Idaho has no cannabis regulator because it has no cannabis program.1
Program
No state cannabis program. Hemp operates under the Industrial Hemp Research and Development Act, Idaho Code Title 22, Chapter 17.1
In effect since
2021 for industrial hemp, with retail hemp provisions added effective July 1, 20261
THC rule
Three layers apply. Handling facilities may obtain hemp from a producer at up to 0.3 percent THC. ISDA guidance states manufactured hemp products must be at 0 percent THC at the point of distribution. Since July 1, 2026, Idaho Code 22-1705(4) requires retail hemp products for ingestion or inhalation to meet 37-2701(u), which sets 0.3 percent total delta-9 THC including THCA.1

How it got here

The legislative record

  1. 2015

    Governor Otter vetoes SB 1146, a bill that would have allowed CBD oil for children with intractable epilepsy, and instead authorizes a limited Epidiolex expanded access study.22

  2. 2021

    Governor Little signs House Bill 126 on April 16, legalizing industrial hemp production, processing and transport in Idaho.13

  3. 2025

    House Bill 7 is signed, adding a mandatory minimum fine for possessing three ounces or less of marijuana. It takes full force and effect on July 1, 2025.11

  4. 2025

    The Legislature adopts HJR 4, the House 58-10-2 on March 5 and the Senate 29-6-0 on March 11, sending voters a constitutional amendment that would give lawmakers sole authority to legalize marijuana and other psychoactive substances.14

  5. 2026

    House Bill 879 is signed April 2 and takes effect July 1, adding Idaho Code 22-1705(4), which subjects establishments offering hemp products for human ingestion or inhalation to the Industrial Hemp Research and Development Act and requires those products to meet the criteria of 37-2701(u) and 37-2705(d)(29)(i).7

  6. 2026

    The Idaho Medical Cannabis Act falls short of the 2026 ballot. The Marijuana Policy Project reports the campaign verified 58,024 signatures against the 70,725 required.16

Who we grow here

Idaho CBD stores, hemp retailers, smoke shops and vape shops

Idaho has no licensed dispensaries, so the legal retail market is CBD and hemp shops, smoke shops and vape shops. They compete for high intent local searches while shoppers, Google and AI assistants all carry confusion about what Idaho actually allows.

  • 01Search results and AI answers still repeat Idaho's older 0 percent guidance without the July 2026 statutory change, so customers arrive with the wrong expectations.
  • 02Ad platforms and marketplaces restrict cannabinoid advertising, which leaves organic search, Maps and AI citations as the only dependable acquisition channels.
  • 03National hemp blogs outrank Idaho storefronts on the exact legality questions Idaho buyers search right before they decide where to shop.

What happens next

Legislation watch

Nothing pending would open an Idaho dispensary market. The live questions are HJR 4 on the November 3, 2026 ballot, which would close the citizen initiative route, and how ISDA reconciles its 0 percent guidance with HB 879. The federal hemp redefinition takes effect November 12, 2026.

  • HJR 4 constitutional amendment

    Certified for the November 3, 2026 ballot as the Grant Legislature Exclusive Authority and Prohibit Citizen-Initiated Measures on Marijuana, Narcotics, and Psychoactive Substances Amendment.15

  • Idaho Medical Cannabis Act and Decriminalize Cannabis Now initiatives

    Both are listed by the Secretary of State among the initiatives that did not qualify for the November 3, 2026 ballot.15

  • HB 879, sale of hemp products for human ingestion or inhalation

    Signed April 2, 2026, effective July 1, 2026, Session Law Chapter 292. Passed the House 53-16-1 and the Senate 24-10-1. It added Idaho Code 22-1705(4), requiring such products to meet the criteria of Idaho Code 37-2701(u) and 37-2705(d)(29)(i) and subjecting those establishments to Title 22, Chapter 17.7

  • HB 772 negligent violation standard for hemp producers

    Signed April 2, 2026, effective July 1, 2026, Session Law Chapter 293. Amends existing law to provide for negligent violations by licensed hemp producers.8

  • Federal hemp redefinition, Public Law 119-37

    Enacted November 12, 2025 and effective one year later, on November 12, 2026. It measures hemp on total THC including THCA, cuts off finished products above 0.4 milligrams total THC per container, and excludes synthesized cannabinoids.20

Answered on the record

Idaho cannabis questions

Is marijuana legal in Idaho in 2026?

No. Idaho prohibits marijuana for every use, with no medical or adult-use program. Under Idaho Code 37-2732, possessing three ounces or less is a misdemeanor carrying a mandatory minimum fine of 300 dollars for anyone 18 or older, in addition to penalties of up to one year in jail and up to 1,000 dollars.4

Is CBD legal to sell in Idaho?

Yes, within a narrow rule. The Idaho Office of Drug Policy states CBD oil is legal in Idaho only when processed from industrial hemp and containing no THC at all. Since July 1, 2026, Idaho Code 22-1705(4) has tied retail hemp products for ingestion or inhalation to the 0.3 percent total THC definition, so confirm current requirements with ISDA.10

Are delta-8, THCA flower or hemp THC drinks legal in Idaho?

It depends on the product and the standard applied. Idaho Code 22-1705(4) requires retail hemp products for ingestion or inhalation to meet the 0.3 percent total THC definition in 37-2701(u), while ISDA guidance still states 0 percent at distribution. High THCA flower fails that test once decarboxylated, and delta-8 remains exposed under the Schedule I tetrahydrocannabinols listing.1

Did Idaho vote on medical marijuana in 2026?

No. The Idaho Medical Cannabis Act did not qualify for the 2026 ballot. The Marijuana Policy Project reports the campaign verified 58,024 signatures against the 70,725 required, and notes that initiatives must also hold 6 percent of registered voters in 18 of Idaho's 35 legislative districts.16

What is HJR 4 and how could it change Idaho cannabis law?

HJR 4 is a constitutional amendment certified for the November 3, 2026 ballot, listed by the Secretary of State as the Grant Legislature Exclusive Authority and Prohibit Citizen-Initiated Measures on Marijuana, Narcotics, and Psychoactive Substances Amendment. It would leave the Legislature as the only route to legalization.15

Do Idaho hemp and CBD retailers need an ISDA license?

Possibly, and the answer is changing. Idaho Code 22-1705(4) now places establishments offering ingestible or inhalable hemp products under the Industrial Hemp Research and Development Act, and 22-1705(5) authorizes ISDA to set fees and penalties by rule. ISDA's published FAQ still states it is not requiring licenses for retailers. Confirm current requirements directly with ISDA.1
