West Riverton Cannabis Guide: Riverton, Wyoming

Riverton is the largest city in Fremont County and it sits within the exterior boundaries of the Wind River Indian Reservation, home to the Eastern Shoshone and Northern Arapaho. That single fact makes it the most legally layered town in the state for a drug case. Whether a matter is handled by city police, the county sheriff, tribal authorities or federal prosecutors can turn on the status of the land where the stop happened and whether the people involved are tribal members. Riverton residents learn those distinctions the way other Wyoming towns learn snow routes.

What none of that layering produces is legal access. Tribal members have pushed both governments toward medical cannabis and hemp since the early 2020s, and as of September 2026 no licensed cannabis storefront operates anywhere on the reservation. Wyoming law governs the rest of the county, so a Riverton resident faces the same prohibition, the same weight thresholds and the same separate under-the-influence offense as someone in Cheyenne, with the added complication that federal jurisdiction can attach on trust land.

The commercial core runs along Federal Boulevard, the US-26 route that carries traffic through town, with older storefronts on Main Street and the shopping cluster near the Riverton Marketplace. Central Wyoming College sits on the north side and brings students who ask the usual questions. Tobacco shops, wellness counters and pharmacies along those corridors sell CBD oils, capsules and balms, and their intoxicating hemp cases were emptied statewide in the summer of 2024.

Wyoming is one of a shrinking handful of states with no cannabis program of any kind. Marijuana sits in Schedule I of the Wyoming Controlled Substances Act, no city or county can decriminalize on its own, and the 2015 hemp extract card for intractable epilepsy is the closest thing to a medical pathway the state has ever created. That card, issued by the Wyoming Department of Health on a neurologist's certification, covers preparations under 0.3 percent THC with a high CBD content - and it comes with no legal in-state source, which is the flaw patients have complained about since the day it passed.

Nothing loosened in 2025 or 2026. Reclassification and decriminalization bills died before introduction in consecutive sessions, and organizers of the ballot petitions have never cleared Wyoming's geographic distribution rule, which demands signatures equal to 15 percent of the last governor's race turnout in two-thirds of the counties. The 2024 attempt gathered enough raw signatures statewide and still failed because it reached the threshold in only 14 of the required 16 counties. No cannabis measure was certified for the November 2026 ballot.

The state also went the other direction on the federal question. After an April 2026 federal order moved state-licensed medical cannabis to Schedule III, Wyoming objected, held a public hearing in June and ruled in July 2026 that all marijuana - including product held under another state's medical program - stays Schedule I under Wyoming law.

Penalty math matters more here than in most states. Anything up to three ounces of plant material lands as a misdemeanor with a year of possible jail time and a fine ceiling of $1,000, and above that weight the charge turns felony, worth five years and $10,000. Concentrate is measured on a far smaller scale, and Wyoming is one of the few states that charges being under the influence as its own offense, which means a blood or urine result can support a case with nothing found in your pocket.

No cannabis brand is legally sold inside Wyoming, so any honest recommendation is about categories and paperwork rather than logos. What a Wyoming shelf can legally hold in 2026 is non-intoxicating hemp: broad-spectrum and isolate CBD tinctures, CBD or CBG capsules, topicals, and pet drops. The test of a good one is the certificate of analysis - a current batch report, from a third-party lab, showing delta-9 THC under 0.3 percent and no delta-8, delta-10, HHC or THC-O, all of which became controlled substances here on July 1, 2024. Anything advertised as high-potency hemp flower, THCA bud or a 25 mg hemp gummy is either mislabeled or illegal in this state. Verified cannabis brands exist across the Colorado and Montana lines, and their products are lawful only where they are sold.

Three things defined the 2025-2026 stretch here. A federal appeals court upheld Wyoming's intoxicating hemp ban in October 2025, ending the industry's best shot at reopening delta-8 sales. Congress then rewrote the federal hemp definition in November 2025, and after a September 2, 2026 stopgap most of those restrictions - a total-THC standard and a 0.4 mg per container cap - land December 11, 2026, while cannabinoids the plant cannot make lose hemp status a month earlier. And in July 2026 Wyoming declined to follow the federal move of medical cannabis to Schedule III, which keeps every product Schedule I under state law regardless of what the DEA does next.
