It’s a common story: a weekend hangout, someone passes around a joint, and no one thinks twice—until red and blue lights cut the moment short. In a state where marijuana remains fully illegal, misdemeanor marijuana possession in Wyoming isn’t a slap on the wrist.
It’s a criminal charge that can follow you long after the smoke clears.
Unlike some neighboring states, Wyoming has not adopted lenient marijuana policies. That means even small amounts—under three ounces—can land someone with a permanent record.
For young adults just entering the workforce, applying to college, or trying to move out on their own, the stakes are especially high.
The law doesn’t ask whether you were experimenting, visiting from Colorado, or thought it was harmless. It only sees possession. This guide explores how the law works, what to expect if charged, and how to protect your future if you’ve made a mistake that suddenly feels much bigger than it should.
Is Marijuana Legal in Wyoming?
Despite the shifting legal landscape across the country, marijuana possession remains fully illegal in Wyoming. This includes both recreational and medical use. The state has some of the strictest cannabis laws in the Mountain West region, with no legal protections even for out-of-state visitors who may legally possess cannabis elsewhere.
This is where many people—especially young adults—get caught off guard.
Under current Wyoming law, possessing less than three ounces of marijuana is classified as a misdemeanor. This might seem minor compared to felony charges, but the consequences are anything but small.
A misdemeanor marijuana possession charge can lead to jail time, fines, a criminal record, and social consequences that extend far beyond the courtroom. Even trace amounts found in your car, backpack, or on your clothing can qualify for charges.
What’s more, Wyoming law treats possession broadly. If marijuana is found in a shared space—like a dorm room, a group tent, or a vehicle—anyone nearby may be charged through what’s known as constructive possession.
This concept means that even if the marijuana wasn’t physically on your person if you had access or control over the area where it was found, law enforcement may argue that you were in possession.
Young people often assume they’ll receive a warning or a fine. But under Wyoming’s zero-tolerance approach, officers typically arrest and charge individuals on the spot. That arrest then becomes part of your public criminal record—accessible to employers, schools, landlords, and even future romantic partners.
For a deeper understanding of the law, refer to the Wyoming Controlled Substances Act , which outlines how substances are classified and penalized.
In a state where marijuana laws remain unchanged while others become more progressive, it’s crucial to understand that bringing cannabis into Wyoming—or possessing it within its borders—can have lasting, life-altering consequences.
What Is Considered Misdemeanor Marijuana Possession in Wyoming?
In Wyoming, misdemeanor marijuana possession applies when an individual is found with less than three ounces of cannabis. While it may seem like a minor amount—especially compared to what is legal just across the border in states like Colorado—Wyoming law treats it as a criminal offense, not a citation or infraction.
Possession includes more than just having marijuana in your pocket. If law enforcement finds marijuana in your backpack, vehicle, shared living space, or even near your belongings, you may still be charged.
This is because Wyoming recognizes constructive possession, which means you don’t have to be holding the substance to be legally responsible for it. If you had access to or control over the location where the marijuana was found, that’s often enough for prosecutors.
Another commonly overlooked detail is paraphernalia. You don’t have to have marijuana on you to face charges—owning a grinder, pipe, vape cartridge, or even a baggie with trace residue can result in a misdemeanor paraphernalia charge.
These charges often accompany possession offenses and can compound the legal consequences.
What raises the stakes even further is location. If you’re caught possessing marijuana on or near school grounds, including high schools, college campuses, or school buses, the penalties can be enhanced.
Law enforcement takes possession near educational facilities especially seriously, regardless of the amount involved.
Under Wyoming Statutes § 35-7-1031(c)(i), it is unlawful for any person to knowingly or intentionally possess a controlled substance unless obtained through a valid prescription or as otherwise authorized by law. Possession of certain amounts of controlled substances is classified as a misdemeanor:
Plant Form: Possession of no more than three (3) ounces.
Liquid Form: Possession of no more than three-tenths (0.3) of a gram.
Powder or Crystalline Form: Possession of no more than three (3) grams.
Pill or Capsule Form: Possession of no more than three (3) grams.
Crack Cocaine: Possession of no more than five-tenths (0.5) of a gram.LSD (Lysergic acid diethylamide): Possession of no more than three-tenths (0.3) of a gram.
Understanding the nuances of these definitions is critical—many first-time offenders don’t realize that a single edible or shared pipe can lead to criminal charges that carry real and lasting impact.
FAQs About Misdemeanor Marijuana Possession in Wyoming
1. Is marijuana decriminalized in Wyoming?
No. Wyoming has not decriminalized marijuana. Possession of any amount is still considered a criminal offense. If you’re caught with less than three ounces, it’s classified as a misdemeanor, which can still result in jail time, a criminal record, and fines.
Larger amounts may result in felony charges. If you are charged with possession, it is crucial to contact an attorney immediately.
2. Will a misdemeanor marijuana charge show up on a background check?
Yes. A misdemeanor marijuana possession charge will appear on most standard background checks, including those used by employers, landlords, and universities. Unless the charge is dismissed or later expunged, it can impact your ability to get a job, housing, or financial aid.
To best avoid impacts on your record, contact a lawyer.
3. Can I be charged if the marijuana wasn’t mine?
Yes. Wyoming law allows for “constructive possession,” which means if the marijuana is found in a place you control or share (like a car, tent, or dorm room), you can be charged even if it didn’t belong to you.
Officers and prosecutors don’t have to prove ownership—only access or control.
4. What should I do if I’m under 21 and get caught with marijuana?
Being under 21 doesn’t shield you from criminal charges. In fact, it may trigger additional penalties, especially if you’re caught on school property. First-time offenders may qualify for deferred prosecution programs, but outcomes vary depending on the case details.
Speaking with an attorney early can protect your rights and future.
5. Can I get a misdemeanor marijuana charge expunged in Wyoming?
Possibly. Wyoming law allows for the expungement of certain misdemeanor offenses after a waiting period and successful completion of all sentencing requirements. However, not every case qualifies.
Consulting with a criminal defense attorney is the best way to determine eligibility and begin the process. For more about expungements, read here.
