Madison Avenue Cannabis Guide: West Yellowstone, Montana

Thirteen hundred people live here year-round and several million pass through. West Yellowstone exists because of the park gate at the end of Yellowstone Avenue, and its economy runs on summer RV traffic, winter snowmobiles, and the snowcoaches that carry visitors in once the interior roads close to cars. The street grid is a tidy rectangle of avenues named after park features, hemmed in on three sides by national forest and on the fourth by Yellowstone itself.

Gallatin County voted for I-190 and applies the 3% local-option tax, so a recreational purchase totals 23%. The unusual part of buying here is not the price, it is the geography. Cross the park boundary a few hundred yards east and you are on federal land where possession is a federal offense. Drive ten miles west over Targhee Pass and you are in Idaho, which treats any amount as a crime. Head south and Wyoming, which covers most of the park, still prohibits recreational cannabis entirely.

The shops sit where the traffic does. Lone Peak Cannabis Company operates at 4420 Targhee Pass Highway and Northstar Evolution, which trades as Northstar Organics, at 1870 on the same road, both on the US Highway 20 approach from the west, with Yellowstoned Cannabis Co. serving visitors in town. There is one more trap worth knowing: the drive north to Big Sky on US Highway 191 passes through the northwest corner of Yellowstone National Park for roughly twenty miles. That stretch is federal park land, and what is legal in your car on either side of it is not legal in the middle.

Initiative 190 carried Montana with about 57% of the vote in November 2020. Adult possession turned legal on January 1, 2021, and the first recreational receipts printed exactly one year later. By January 2026 the state had crossed $1 billion in cumulative adult-use revenue, and 2025 finished as the biggest year yet at roughly $327 million in combined medical and recreational sales, about 90% of that recreational. Cannabis is now a normal part of main-street commerce here, with one of the highest storefront-per-resident ratios in the country.

The thing that confuses visitors is the county map. Adult-use retail is allowed only where a majority backed I-190 - the green counties - while the red half of Montana stays closed until its own voters flip it. Custer County did exactly that in November 2024, and Miles City started selling recreational product on January 1, 2025. Cities get a say too. Billings voters barred adult-use storefronts inside the city limits in November 2021, which is why the recreational shops serving Billings sit in Lockwood and Laurel instead.

Money and limits are simple once you know them. Recreational purchases carry a 20% state tax; a registered patient pays 4%. Most counties tack on a local-option tax of up to 3%. The daily ceiling is one ounce of flower, and inside that ounce you may not exceed 8 grams of concentrate or 800 milligrams of edible THC. Two mature plants and two seedlings per adult are legal at home, locked and out of sight.

Two changes reshaped 2025 and 2026. SB 375 and HB 49 pulled almost every hemp-derived THC gummy and seltzer off gas-station coolers, pushing that demand into licensed stores. Then HB 636 cut edible servings from 10 milligrams to 5 on July 1, 2026, so the gummy you bought last spring is packaged differently now.

Montana retail is dominated by vertically integrated homegrown chains rather than national multistate operators. The names you will see across multiple towns include Bloom Montana, Lionheart Cannabis, Top Shelf Botanicals, Elevated, Lone Peak Cannabis Company, SweetGrass, Seed of Life Labs, Frosteez, Honey Sour, Dancing Goat Gardens, and Apogee Gardens. Because the same license covers cultivation and the sales floor, house-grown flower usually carries the store name on the jar, and the in-house cartridge or gummy line is the cheapest thing on the menu. Cross-shopping matters more here than brand loyalty: a strain that costs $12 a gram in one town may be $7 forty miles away.

Prices keep sliding while volume climbs: 2025 set a sales record even as per-gram pricing fell, and the first five months of 2026 ran ahead of 2025 on the recreational side while medical kept shrinking. SB 27 froze new licenses through June 30, 2027, so the shop count is fixed and competition is playing out on price and loyalty programs instead of new storefronts. Red counties holding opt-in votes are the only source of new territory.
