Wyoming is one of the most restrictive cannabis states in the country. There is no medical cannabis program, no adult-use program, no decriminalization, and no meaningful reform legislation has advanced in the 2023, 2024, 2025, or 2026 legislative sessions. Cannabis cultivation of any amount is a felony. Hemp cultivation is legal with a license from the Wyoming Department of Agriculture (WDA), though the 2026 application deadline has already passed. What any Wyoming resident can do right now is purchase cannabis seeds, including high-THC varieties, for collecting and to be prepared if and when Wyoming legalizes home cultivation. Cannabis seeds are legally classified as hemp under the 2018 Farm Bill — the seed itself contains no meaningful THC regardless of what the plant would eventually produce. This post covers Wyoming’s hemp licensing process, current cannabis law, and where things stand on reform.

Can You Grow Cannabis at Home in Wyoming?
No. Cannabis cultivation is a felony in Wyoming at any scale. There is no personal use exception, no medical patient exception, and no plant count threshold that reduces cultivation to a misdemeanor.
Possession of three ounces or less is a misdemeanor carrying up to 12 months in jail and a $1,000 fine. Possession of more than three ounces is a felony carrying up to five years in prison. Cultivation is treated as a more serious offense than simple possession — any cultivation of cannabis, regardless of the amount or number of plants, is a felony under Wyoming law.
Wyoming has made virtually no progress on reform. No city or municipality in Wyoming has successfully decriminalized marijuana. The Cheyenne City Council rejected a decriminalization proposal 6-3 in March 2023. Lawmakers made no progress on cannabis reform bills in the 2023, 2024, 2025, or 2026 legislative sessions.
Hemp Is Legal to Grow in Wyoming With a License
Hemp — cannabis with no more than 0.3% delta-9 THC by dry weight — is legal to cultivate in Wyoming under a producer license issued by the Wyoming Department of Agriculture (WDA). Wyoming legalized hemp cultivation through HB 171 in 2019, aligning with the federal 2018 Farm Bill. The USDA approved Wyoming’s state hemp regulatory plan on February 20, 2020.
Unlike Kansas, Nebraska, and several other states that have fully transferred hemp producer licensing to the USDA, Wyoming maintains its own state-level hemp program administered by WDA. Applications go to WDA, not the USDA HeMP platform. WDA Analytical Services Lab handles compliance testing, and WDA uses the eHemp online platform to report monthly, yearly, and disposal reports to the USDA.
Wyoming law specifies that no municipality in the state can restrict the cultivation or processing of licensed hemp on private property. Licensed hemp growers have a clear preemption against local restrictions.
Licenses are valid through December 31 of the year issued and must be renewed annually.
How to Get a Wyoming Hemp Producer License
Applications are submitted through the WDA Agriculture Licensing website at agriculture.wy.gov/hemp-program. Applications can be submitted online or by paper form.
2026 deadline note: The 2026 application deadline was March 9, 2026 at 5:00 PM and has passed. The next application window will open in early 2027. Monitor the WDA hemp program page at agriculture.wy.gov/hemp-program for announcements.
When the window opens, the process works as follows:
- Review WDA’s hemp program rules and requirements at agriculture.wy.gov/hemp-program before applying.
- Gather required documentation including photo identification, proof of business registration if applicable, aerial maps of proposed cultivation sites with GPS coordinates, a criminal history report, and a statement outlining your intended hemp usage and growing practices.
- Complete the Hemp License Application Form online through the WDA Agriculture Licensing website, or download and complete the paper form.
- Pay the $750 application fee (or $500 for non-profit and educational organizations) at the time of application.
- Submit the completed application with all required documentation and the application fee.
- After approval, register your grow sites with your local USDA Farm Service Agency (FSA) office for annual acreage reporting.
You can reach the WDA Technical Services Division with hemp program questions by phone at 307-777-3502. Modifications to a submitted application can be made by completing and submitting the Hemp Amendment Form.
What the License Requires
Once licensed:
Pre-harvest THC testing. WDA Analytical Services Lab performs compliance testing on hemp crops. All lots must be tested before harvest to confirm THC compliance at or below 0.3% delta-9 THC. Crops testing above the threshold must be destroyed and a destruction report must be filed.
Monthly and annual reporting through eHemp. WDA uses the eHemp online platform to collect and report required production data to the USDA. Growers must submit monthly, annual, and disposal/remediation reports through this system.
Random audits. WDA conducts random audits of approximately 10% of all licensees annually to verify that hemp is being produced in accordance with Chapter 61 Rules.
Annual renewal. Licenses expire December 31 each year and must be renewed. Applications for the following year are accepted through an annual window.
Costs to Know Before You Apply
Application fee: $750 for individuals and businesses; $500 for non-profit organizations and educational institutions. This fee is non-refundable.
Testing fees. WDA Analytical Services Lab handles compliance testing. Testing fees vary depending on sample type and analysis requested. Contact the lab at (307) 742-2984 for current pricing and sampling instructions before submitting samples.
GPS modification fee. If GPS coordinates for registered cultivation sites need to be changed after licensure, an amendment fee applies.
Wyoming’s $750 application fee is on the higher end compared to other states in this series. The limited number of licensed growers in the state — a small and sparsely populated agricultural state — means the program has relatively modest infrastructure compared to major hemp-producing states.
What Is Changing: Wyoming Cannabis Legislation in 2025 and 2026
The short answer is very little. Wyoming has been among the most resistant states in the country to cannabis reform, and that has not changed through the 2026 session.
No medical cannabis bill advanced (2025 or 2026). Multiple medical cannabis bills have been introduced in Wyoming over the years, but none have advanced to a floor vote in either chamber. No medical bill with meaningful momentum was introduced in the 2025 or 2026 sessions.
No decriminalization bill advanced (2025 or 2026). A 2024 budget session introduced HB 204, which would have made possession of up to three ounces a civil offense with a $100 fine. It did not receive the two-thirds majority needed to pass as a non-budget bill in the short session. No comparable bill advanced in 2025 or 2026.
No recreational legalization bills advanced. No recreational or adult-use legalization bill has received meaningful committee action in Wyoming.
Public support exists but has not translated to reform. A 2025 statewide survey found approximately 65% of Wyoming respondents support legalizing recreational marijuana. That public sentiment has not yet translated into legislative movement, reflecting the conservative political culture of the legislature.
No citizen initiative process. Wyoming does not have a citizen initiative process for statutes. Voters cannot put cannabis reform directly on the ballot — all change must go through the legislature. This is a structural constraint that makes reform slower than in states where citizen initiatives are available.
Colorado and Montana context. Wyoming is bordered to the south by Colorado, which has had full adult-use cannabis since 2012, and to the north by Montana, which legalized adult use in 2020. Cross-border travel for cannabis is a reality for Wyoming residents, but it has not generated legislative momentum in Cheyenne.
Wyoming’s Limited CBD Access
Wyoming passed HB 32 in 2015, creating a narrow exception for patients with intractable epilepsy. The law allows qualifying patients with a physician’s recommendation to possess and use hemp extract containing no more than 0.3% THC and at least 5% CBD.
There is no dispensary or in-state supply chain supporting this access. Patients must source compliant products from out-of-state legal sources. The law provides a limited affirmative defense but is not a functional medical program.
This is the only patient cannabis access in Wyoming.
Outdoor Growing in Wyoming
Wyoming spans USDA hardiness zones 3a through 6b, making it one of the most climatically challenging states for outdoor growing in the country. The high plains and basin areas of central and eastern Wyoming fall in zones 4b and 5a. The lower-elevation areas in the Big Horn Basin and around Casper reach zones 5b and 6a. The outdoor growing season runs from roughly late May through early September in most of the state, with a short frost-free window often under 100 days in many areas.
Wyoming’s short growing season, high elevation, and variable weather make variety selection critical for licensed hemp growers. Photoperiod hemp strains that mature late in October are generally not suited to most of Wyoming — frost risk arrives long before those varieties would reach harvest.
Autoflowering hemp strains — which finish in 70 to 90 days regardless of light cycle — are the most practical choice for Wyoming’s outdoor growing conditions. They allow licensed growers to plant after the last frost risk has passed in late May or early June and harvest well before fall frosts arrive in late August or early September at higher elevations. In the warmer basin areas, there may be room for a slightly wider window with careful variety selection.
If you are a licensed hemp grower looking for genetics suited to Wyoming’s challenging climate, our USDA zone map tool can help you identify your zone and planting window. We carry CBD seeds for outdoor production, and if you want to be ready for when Wyoming’s laws change, you can browse our full seed catalog — including high-THC feminized varieties. The seeds themselves are legally classified as hemp and are legal to purchase and ship to Wyoming today.
Penalties for Growing Without a License
Cannabis cultivation in Wyoming is a felony at any scale:
Any cultivation of cannabis without a license is a felony. Possession of three ounces or less is a misdemeanor carrying up to 12 months in jail and a $1,000 fine. Possession of more than three ounces is a felony carrying up to five years in prison. Cultivation bypasses the misdemeanor tier entirely and is treated as a separate and more serious offense.
Sale or delivery of cannabis carries escalating felony penalties based on the amount involved, with the most serious charges carrying up to 10 years in prison and $10,000 in fines.
Growing hemp without a WDA producer license is also illegal under both Wyoming state law and federal law.
Frequently Asked Questions
Is it legal to grow cannabis at home in Wyoming?
No. Cannabis cultivation is a felony in Wyoming at any scale. There is no personal use exception, no medical program, and no decriminalization. Wyoming is one of the most restrictive cannabis states in the country.
Can I grow hemp at home in Wyoming?
You can grow hemp on your property with a valid WDA hemp producer license. The application window for 2026 closed on March 9, 2026. The next window will open in early 2027. The application fee is $750 for individuals and businesses. Applications and renewal information are at agriculture.wy.gov/hemp-program.
Does Wyoming have any medical cannabis program?
No. Wyoming has no medical cannabis program as of 2026. A narrow 2015 law (HB 32) allows patients with intractable epilepsy to possess low-THC, high-CBD cannabis oil with a physician’s recommendation, but there is no dispensary or in-state supply chain. No medical cannabis bill has advanced through the legislature.
Has Wyoming made any progress on cannabis reform?
No meaningful progress has been made in the 2023, 2024, 2025, or 2026 legislative sessions. Decriminalization and medical cannabis bills have been introduced but have not advanced to floor votes. Wyoming also lacks a citizen initiative process, meaning voters cannot put cannabis reform directly on the ballot.
Is Wyoming affected by legal cannabis in neighboring states?
Colorado to the south has had full adult-use cannabis since 2012, and Montana to the north legalized adult use in 2020. Wyoming residents have legal access in neighboring states but face felony charges if they bring cannabis back into Wyoming.
Can I buy cannabis seeds in Wyoming?
Yes. Cannabis seeds — including high-THC feminized varieties — are legal to purchase in Wyoming. Cannabis seeds are legally classified as hemp under the 2018 Farm Bill — the seed itself contains no meaningful THC regardless of what the plant would eventually produce. Many Wyoming residents purchase seeds now for collecting and to be ready if and when the state legalizes home cultivation.
