Wyoming does not permit recreational or medicinal Delta‑9 THC that exceeds the federal hemp threshold of 0.3 % THC by dry weight. In 2026, only hemp‑derived Delta‑9 products that stay under that limit are legal; any concentrate, vape, or edibles containing higher concentrations remain classified as a controlled substance under both state and federal law.
Wyoming Statutes on Delta‑9 THC
Wyoming’s “Controlled Substances Act” mirrors the federal schedule, placing Delta‑9 THC above 0.3 % in Schedule I. The state adopts the 2018 Farm Bill definition of hemp, which permits cannabinoids extracted from Cannabis sativa L. with a THC concentration of 0.3 % or less. In 2024 the Wyoming Legislature enacted SB 12, tightening enforcement by requiring testing labs to be state‑approved and granting law‑enforcement the authority to seize any product that exceeds the limit. Violations can result in felony charges, fines up to $10,000, and forfeiture of equipment.
Federal Influence and the 2024 Farm Bill
The 2024 amendment to the Farm Bill clarified that “Delta‑9 THC derived from hemp” is permissible if it meets the 0.3 % threshold, but it also mandated that all states maintain consistent testing standards. Wyoming complied by adopting ASTM D7608‑21 testing protocols, ensuring that products sold in licensed dispensaries are reliably below the legal limit. However, the amendment did not legalize Delta‑9 for medical use; that remains a separate federal and state consideration.
Practical Implications for Residents and Businesses
- Consumers: Only products labeled as “hemp‑derived Delta‑9” with verified lab results under 0.3 % can be purchased legally at licensed retailers or online. Possession of higher‑potency Delta‑9 can lead to criminal prosecution.
- Businesses: Retailers must maintain a chain‑of‑custody log, display third‑party certificates of analysis (COA), and store products in compliance with the state’s packaging and labeling rules, which prohibit claims of therapeutic benefit. Failure to adhere can trigger license revocation.
- Employers: Wyoming’s drug‑free workplace statutes allow testing for Delta‑9 above the legal limit, and positive results may be grounds for disciplinary action.
Future Outlook and Possible Legislative Changes
Legislative proposals for 2027 include a “Medical Delta‑9 Act” that would create a limited exemption for patients with a physician’s recommendation, modeled after Colorado’s 2022 amendment. Advocacy groups argue that the current binary approach—legal under 0.3 % or illegal—fails to address therapeutic needs. Conversely, law‑makers express concern about regulatory burden and cross‑border enforcement. Monitoring the Wyoming Senate’s 2026 session will be critical for stakeholders.
Frequently Asked Questions
What is the legal definition of Delta‑9 THC in Wyoming?
Wyoming defines Delta‑9 THC as any cannabinoid that produces psychoactive effects and exceeds 0.3 % THC by dry weight. Hemp‑derived Delta‑9 that stays below that threshold is exempt under the state’s adoption of the federal hemp definition.
Can I grow my own Delta‑9 THC plants at home?
No. Home cultivation of cannabis plants that could yield Delta‑9 THC above 0.3 % is prohibited and classified as a Schedule I activity, punishable by felony charges.
Are there any medical exemptions for Delta‑9 THC?
As of 2026, Wyoming has not enacted a medical program for Delta‑9 THC. Patients must seek alternative therapies that are federally recognized, such as CBD with low THC content.
How do I verify that a product complies with the 0.3 % limit?
Legally sold products must provide a COA from a state‑approved lab showing the exact THC concentration. The COA should be dated, include batch numbers, and be readily accessible to the consumer.
What penalties apply for selling illegal Delta‑9 THC?
Selling Delta‑9 THC above the legal limit is a felony in Wyoming, carrying up to five years imprisonment, fines up to $10,000, and mandatory forfeiture of all related assets.
