Is Marijuana Legal in Wyoming? State Laws and Regulations Explained
Meta description: Find out whether marijuana is legal in Wyoming, what state law says about possession, medical cannabis, hemp products, driving, and penalties.
Marijuana remains illegal for recreational use in Wyoming, and the state does not operate a broad medical-marijuana program. Possessing cannabis can lead to criminal penalties, even if it was purchased legally in another state. Wyoming does allow certain hemp products and has a narrow exception for qualifying hemp extract used to treat intractable epilepsy. Knowing the difference between marijuana, hemp, and limited medical exceptions can help residents and visitors avoid costly legal problems.
Is Marijuana Legal in Wyoming?
No. Wyoming has not legalized recreational marijuana. State law generally prohibits possessing, using, growing, selling, or distributing marijuana unless a specific legal exception applies. A person cannot legally bring cannabis into Wyoming from a state where recreational or medical marijuana is permitted.
Wyoming’s prohibition applies regardless of whether a person uses cannabis for recreation, has a medical recommendation from another state, or bought the product from a licensed dispensary elsewhere. A neighboring state’s laws do not change what is legal once someone is in Wyoming.
Marijuana is also illegal under federal law. Federal rules are especially relevant on federal property, such as national parks and certain federal lands, where state legalization would not make possession lawful. Because Wyoming does not legalize recreational cannabis in the first place, state and federal restrictions may both matter.
Wyoming Marijuana Laws at a Glance

This table is a general summary, not a substitute for the current statute or legal advice. Charges and consequences can depend on the substance, amount, location, prior convictions, and alleged intent.
Possession Penalties in Wyoming
Wyoming treats marijuana possession as a criminal offense. Under Title 35 of the Wyoming Statutes, possession of three ounces or less is generally a misdemeanor. The statute provides for up to 12 months in jail, a fine of up to $1,000, or both. The specific outcome in a case can vary, and the maximum penalty is not necessarily the penalty imposed.
Possessing more than three ounces can be charged as a felony. The statutory maximum is generally up to five years in prison, a fine of up to $10,000, or both. The amount is only one factor: evidence of distribution, a prior record, or other alleged offenses may affect the charge and potential sentence.
Wyoming law also addresses marijuana use and possession in circumstances beyond a simple personal-possession case. For example, alleged possession with intent to deliver may be treated differently from possession for personal use. The facts, evidence, and applicable statute determine how prosecutors classify an incident.
Possession of Marijuana Paraphernalia
Items used to grow, process, or consume marijuana can create a separate legal issue. Wyoming law prohibits certain conduct involving drug paraphernalia, including possession in circumstances covered by the statute. A paraphernalia offense may carry its own penalties, apart from any marijuana-possession charge.
Whether an item qualifies as paraphernalia can depend on its design, how it was used, and the surrounding evidence. The term does not automatically mean every ordinary household item is illegal; the applicable statute and circumstances matter.
Is Medical Marijuana Legal in Wyoming?
Wyoming does not have a comprehensive medical-marijuana program that allows qualifying patients to purchase and use cannabis under a state-issued medical card. A medical recommendation or cannabis card from another state does not provide a general exemption from Wyoming’s marijuana laws.
The state does have a narrow exception relating to hemp extract for certain people with intractable epilepsy. Wyoming enacted a limited law allowing qualifying individuals to possess a defined hemp-extract product under specified conditions. The exception is not equivalent to a general medical-cannabis program: it does not authorize patients to possess ordinary marijuana products or use a dispensary card as a defense.
People considering this exception should verify the current requirements in the statute and consult a qualified attorney or medical professional. Product composition, documentation, eligibility, and compliance with the law’s conditions can all be important.
Hemp, CBD, and Delta-8 Products
Hemp and marijuana both come from the cannabis plant, but the law distinguishes them. In general, hemp is defined by its low delta-9 THC concentration, while marijuana refers to cannabis outside the applicable hemp definition. Federal law generally sets the hemp threshold at no more than 0.3% delta-9 THC by dry weight; state rules and product-specific requirements also matter.
That distinction does not mean every product labeled “hemp,” “CBD,” or “legal THC” is automatically lawful in Wyoming. Product ingredients, THC content, how the product was made, labeling, and applicable state or federal rules can affect its status. A label alone does not prove that a product complies with the law.
CBD products may contain trace THC or be mislabeled. Products marketed as delta-8 THC or other hemp-derived intoxicating cannabinoids can raise additional legal and regulatory questions. Consumers should check current Wyoming requirements and reliable product-testing information rather than assume that an item sold online or in a store is permitted.
For federal background on the legal distinction between hemp and marijuana, see the Agriculture Improvement Act of 2018 and current guidance from the U.S. Food and Drug Administration. Federal hemp definitions do not override every state restriction or make unapproved health claims lawful.
Can You Grow Marijuana in Wyoming?
Growing marijuana for personal use is not a legal workaround in Wyoming. Cultivation can lead to criminal charges, and the possible consequences depend on the amount, circumstances, and applicable provisions of state law. A person should not assume that a small number of plants will be treated as legal or exempt from prosecution.
Growing hemp is different from growing marijuana, but hemp production is subject to its own rules and authorization requirements. A person interested in commercial hemp cultivation should consult the Wyoming Department of Agriculture and confirm current licensing, testing, and compliance procedures before planting.
Buying, Selling, and Transporting Cannabis
Buying marijuana in another state does not make it legal to possess in Wyoming. The same is true of cannabis ordered online or carried across state lines. Transporting marijuana into Wyoming may expose a person to state criminal charges and, depending on the facts and route, possible federal consequences.
Selling or distributing marijuana can carry more serious penalties than simple possession. Wyoming law distinguishes among conduct and circumstances, including the amount and whether the alleged offense involves delivery or intent to deliver. A person should not rely on another state’s licensed dispensary system as protection from Wyoming law.
Air travel adds another layer of risk. Airports and flights are subject to federal rules, and cannabis remains prohibited under federal law even when a state permits it. Travelers should not assume that a state airport or a flight within a legal-cannabis state makes marijuana transport lawful.
Marijuana and Driving in Wyoming
Driving while impaired by marijuana is illegal. Wyoming’s DUI law covers driving while under the influence of a controlled substance to a degree that makes a person incapable of safely driving. A marijuana-related DUI may be investigated even if the driver has no alcohol in their system.
Cannabis impairment can affect reaction time, attention, coordination, and judgment. Unlike a simple rule based on the presence of alcohol, marijuana impairment may be assessed through the circumstances of the stop, driving behavior, observations, and testing. A positive test does not, by itself, explain every legal issue in a case; the facts and applicable law matter.
Drivers should not use marijuana before driving or ride with someone who may be impaired. A DUI arrest can bring consequences beyond a criminal sentence, including possible effects on driving privileges, insurance, and employment.
Workplace and Housing Considerations
Because marijuana is illegal under Wyoming law, employers may enforce workplace drug policies and take action consistent with applicable law. Even in states with legal recreational cannabis, legalization does not always require an employer to allow use or impairment at work. In Wyoming, workers should review employer policies and applicable state and federal requirements.
Housing rules can also matter. Landlords may restrict illegal drug activity under lease terms, and federally subsidized housing is subject to federal requirements. A person should review the lease and housing program rules rather than assume that private use is protected.
What to Do If Facing a Marijuana Charge
A marijuana arrest or citation should be taken seriously, even when the amount appears small. The charge may involve separate allegations, such as paraphernalia, impaired driving, distribution, or conduct on federal property. A person facing a case can take practical steps while avoiding actions that might complicate it.
- Read the paperwork carefully. Note the alleged offense, court, deadlines, and any release conditions.
- Do not miss a court date. Failure to appear can create additional legal problems.
- Avoid discussing case details publicly. Social media posts or informal statements may become relevant evidence.
- Consult a Wyoming criminal-defense attorney. An attorney can assess the charge, evidence, and available legal options.
- Keep product and medical documentation. Records may help clarify what a product was, but they do not automatically establish a legal defense.
Where to Check Current Wyoming Rules
State statutes can change, and cannabis rules may be affected by new legislation, court decisions, or agency guidance. For current information, consult the Wyoming Legislature’s Title 35 statutes, the Wyoming Department of Agriculture for hemp-related matters, and a licensed Wyoming attorney for advice about a specific situation.
Bottom line: Recreational marijuana is illegal in Wyoming, and the state does not provide a general medical-marijuana exemption. Limited hemp-related rules do not make ordinary cannabis legal. Possession, cultivation, distribution, and impaired driving can carry serious consequences, so anyone unsure about a product or situation should verify the law before acting.
