Felony Charges for THC Concentrates and Edibles in Wyoming: Weight Thresholds Explained

Driving north across the state line from Fort Collins or Craig, Colorado, or heading east from Salt Lake City, Utah, with a few legally purchased vape cartridges or a tin of cannabis gummies is one of the fastest ways to end up in handcuffs in Wyoming. Millions of tourists heading toward Yellowstone National Park, Jackson Hole, or Cheyenne assume that carrying a personal-use supply of dispensary products will at worst result in a minor ticket. Instead, they are shocked to learn about felony charges for THC concentrates and edibles in Wyoming, where possessing a single standard 1-gram vape pen cartridge can legally trigger the exact same felony classification as carrying over three ounces of raw marijuana flower.

Unlike its neighbors, Wyoming has not legalized medical or recreational cannabis in any form. Under Wyo. Stat. Ann. § 35-7-1014(d)(xiii) and Wyo. Stat. Ann. § 35-7-1014(d)(xxi), both marijuana and tetrahydrocannabinols (THC) remain strictly Schedule I controlled substances. Because Wyo. Stat. Ann. § 35-7-1031(c) divides misdemeanor and felony possession strictly by the physical form and total weight of the item seized, understanding how Wyoming crime labs and prosecutors weigh concentrates, oils, and infused foods is vital to keeping a permanent felony off your record.

Wyoming's Statutory Weight Thresholds Under Wyo. Stat. Ann. § 35-7-1031(c)

Under the Wyo. Stat. Ann. § 35-7-1031(c)(i), simple possession of a Schedule I or II controlled substance is a misdemeanor-punishable by up to 12 months in county jail and a $1,000 fine-only if the total weight stays at or below specific form-based statutory ceilings. The moment the weight crosses those tiny thresholds, Wyo. Stat. Ann. § 35-7-1031(c)(iii) elevates possession of marijuana or THC to a felony punishable by up to 5 years in prison and a $10,000 fine.

Calculating Edible Weight vs. Plant Form: The Carrier Weight Trap

The biggest shock in Wyoming drug law is the "carrier weight" or mixture rule codified in Wyo. Stat. Ann. § 35-7-1031(d). That subsection explicitly states that for purposes of determining misdemeanor versus felony weight under Wyo. Stat. Ann. § 35-7-1031(c), the weight of a controlled substance includes the total weight of any mixture, compound, or other substance containing a detectable amount of the controlled substance.

The Wyoming Supreme Court validated this harsh mixture rule in Smith v. State, 964 P.2d 421 (WY Supreme Court 1998), holding that when a controlled substance is mixed into a liquid or carrier medium, the state can weigh the entire mixture-not just the pure active drug-to elevate a misdemeanor to a felony under Wyo. Stat. Ann. § 35-7-1031(d). Consequently, if you buy a bag of THC gummies containing only 100 milligrams (0.1 grams) of actual THC, the Wyoming Division of Criminal Investigation, State Crime Laboratory, Cheyenne does not extract the pure THC. Instead, analysts weigh the sugar, gelatin, and fruit flavoring-or in the case of a THC soda or vape cartridge, the entire liquid carrier volume-which effortlessly pushes a minuscule dose of THC past the 0.3-gram liquid or 3-gram solid felony line.

Border Stops Returning from Colorado and Out-of-State Medical Cards

Law enforcement agencies in southern and western Wyoming-particularly along US-287 between Fort Collins and Laramie, I-25 north into Cheyenne, and I-80 into Evanston and Rock Springs-routinely stop drivers who visited dispensaries just across the border. Many arrested travelers immediately show the trooper a valid medical marijuana registry card from Colorado, Utah, Montana, or California, assuming reciprocity protects them.

In Wyoming, offering an out-of-state medical card at the roadside is an admission of possession, not a legal shield. In Burns v. State, 246 P.3d 283 (WY Supreme Court 2011) and Bruyette v. State, 253 P.3d 512 (WY Supreme Court 2011), the Wyoming Supreme Court ruled that possessing an out-of-state medical marijuana card or physician recommendation provides zero legal defense to a felony or misdemeanor charge under Wyo. Stat. Ann. § 35-7-1031(c). Furthermore, after the 2018 federal Farm Bill legalized hemp containing no more than 0.3% delta-9 THC on a dry-weight basis (codified in Wyoming at Wyo. Stat. Ann. § 35-7-1063), prosecutors must still prove through quantitative lab testing that a seized gummy or vape cartridge exceeds the 0.3% delta-9 THC hemp threshold.

Strategies to Downgrade Felony Concentrate and Edible Charges to Misdemeanors

If you are charged with felony possession of THC liquid, wax, or edibles under Wyo. Stat. Ann. § 35-7-1031(c)(iii), a knowledgeable Wyoming defense attorney can deploy several statutory and forensic defenses to get the felony dismissed or reduced to a misdemeanor:

• Challenging the "In Plant Form" Charging Defect on Edibles: Under Wyo. Stat. Ann. § 35-7-1031(c)(i)(A), the 3-ounce misdemeanor provision specifically refers to a controlled substance "in plant form." When prosecutors mistakenly charge a defendant with possessing more than 3 ounces of marijuana "in plant form" based on baked goods, chocolate bars, or gummies manufactured from extracted distillate, defense counsel can file a motion to dismiss the felony count because THC distillate edibles contain zero plant material.
• Excluding the Weight of Non-Consumable Vape Hardware: A standard 510-thread glass and metal vape cartridge weighs between 5 and 10 grams empty, while holding only 0.5g or 1.0g of oil. If an arresting officer weighed the entire metal and glass cartridge on a roadside scale to allege felony weight, your lawyer can demand that the Wyoming Division of Criminal Investigation, State Crime Laboratory, Cheyenne extract and weigh only the interior liquid, excluding the heavy cartridge casing.
• Demanding Quantitative Delta-9 THC vs. Hemp Testing: Under Wyo. Stat. Ann. § 35-7-1063, hemp and hemp-derived products containing 0.3% or less delta-9 THC on a dry-weight basis are excluded from the Wyoming Controlled Substances Act. For heavy edibles (such as a 50-gram gummy pack or brownie containing 100mg of THC, where 100mg is only 0.2% of the total 50,000mg weight), an aggressive defense lawyer can argue that the product's dry-weight concentration falls below 0.3% delta-9 THC!
• Negotiating a Charge Reduction to Misdemeanor Plant Possession or Use: Even when lab weights exceed 0.3 grams of liquid, county prosecutors in Cheyenne, Laramie, and Green River frequently agree in plea negotiations for first-time offenders with clean records to amend a Wyo. Stat. Ann. § 35-7-1031(c)(iii) felony down to a single misdemeanor count under Wyo. Stat. Ann. § 35-7-1031(c)(i) or misdemeanor unlawful use under Wyo. Stat. Ann. § 35-7-1039 (which carries a maximum of 6 months and a $750 fine).

Step-by-Step Process After a THC Concentrate or Edible Arrest in Wyoming

Whether you were stopped in Cheyenne, Laramie, Casper, Rock Springs, or Jackson, here is how to navigate the criminal court process when facing felony THC charges.

Step 1: Do Not Admit Knowledge of THC Potency or Offer Dispensary Receipts

Never volunteer your dispensary receipt or out-of-state medical card to the officer. Prosecutors use dispensary labels and receipts to prove that you "knowingly or intentionally" possessed a Schedule I THC product rather than legal CBD or hemp.

Step 2: Attend Your Circuit Court Initial Appearance and Preliminary Hearing

Felony concentrate charges begin in your local Circuit Court, such as Laramie County Circuit Court, First Judicial District, Cheyenne, Albany County Circuit Court, Second Judicial District, Laramie, or Sweetwater County Circuit Court, Third Judicial District, Rock Springs. Your attorney can cross-examine the arresting officer at the preliminary hearing under Wyo. R. Crim. P. § 5.1 or negotiate a pre-bindover reduction to a misdemeanor so the case never reaches felony District Court.

Step 3: Demand Quantitative Crime Lab Testing and Net Liquid Weighing

If the case is bound over to Laramie County District Court, First Judicial District, Cheyenne, Albany County District Court, Second Judicial District, Laramie, Natrona County District Court, Seventh Judicial District, Casper, or Teton County District Court, Ninth Judicial District, Jackson, file a formal written demand for discovery and quantitative lab analysis under Wyo. R. Crim. P. § 16. Require the state crime lab to separate packaging and vape hardware from the net substance and quantify the exact dry-weight percentage of delta-9 THC.

Step 4: File Pretrial Motions to Dismiss or Suppress

If the stop involved an unlawful detention or a defective charging Information that misclassified distillate edibles as "plant form," your lawyer will file a written motion to suppress or dismiss the defective information under Wyo. R. Crim. P. § 12(b)(3).

Step 5: Pursue Misdemeanor Amendment or First-Offender Deferral

If the search and lab results hold up, your attorney can negotiate to amend the felony charge down to a misdemeanor under Wyo. Stat. Ann. § 35-7-1031(c)(i) or secure a first-offender conditional discharge under Wyo. Stat. Ann. § 35-7-1037 so that no conviction ever enters on your permanent record.

How Much Does it Cost in Wyoming?

Facing a felony THC vape or edible prosecution in Wyoming carries several direct and indirect financial costs:

• Felony Statutory Fine (Wyo. Stat. Ann. § 35-7-1031(c)(iii)): Up to $10,000 (plus up to 5 years in prison).
• Misdemeanor Statutory Fine (Wyo. Stat. Ann. § 35-7-1031(c)(i)): Up to $1,000 (plus up to 12 months in county jail).
• Court Costs and Victim Compensation Surcharges: Typically $150 to $350 in mandatory court automation fees and crime victims' compensation assessments.
• Addiction Severity Index (ASI) Evaluation: $150 to $300 required by Wyoming courts prior to sentencing or probation placement.
• Criminal Defense Lawyer Fees: $3,500 to $8,500 for felony THC concentrate defense, suppression motions, and plea negotiations in District Court (compared to $1,500 to $3,500 if resolved as a misdemeanor in Circuit Court).

How Long Does the Process Take?

The timeline for resolving a THC concentrate or edible charge in Wyoming depends largely on crime lab backlogs:

• Circuit Court Misdemeanor Resolution: If your lawyer negotiates an early reduction to a misdemeanor at the Circuit Court stage, the case can often be resolved in 30 to 60 days.
• DCI State Crime Lab Quantitative Testing: Sending vape cartridges or edibles to the Wyoming Division of Criminal Investigation, State Crime Laboratory, Cheyenne for net weight and delta-9 THC quantification typically takes 60 to 120 days.
• District Court Felony Litigation: A contested felony THC case generally takes 4 to 8 months from arrest to final disposition, subject to the 180-day speedy trial limit after arraignment under Wyo. R. Crim. P. § 48(b).

Because a felony conviction for a single THC vape pen or bag of gummies can strip away your firearm rights, professional licenses, and career prospects, do not plead guilty without challenging the state's weight calculations.
