Custer Avenue Cannabis Guide: Helena, Montana

Helena is a government town wrapped around a gold-rush gulch. The Capitol, the state agencies, and the Supreme Court employ a large share of the workforce, Carroll College sits above the west side, and the Fort Harrison VA Medical Center serves veterans from across western Montana. The Cannabis Control Division that writes the rules for every dispensary in the state has its offices here, which gives the local market an unusual proximity to its own regulator.

Lewis and Clark County backed I-190 in 2020 and its voters approved the 3% local-option tax on adult-use sales in June 2022, so a recreational purchase totals 23%. The wrinkle in Helena is employment rather than law: thousands of residents work for state agencies, federal offices, or the VA, and several of those employers apply drug policies that ignore Montana's legalization entirely. Plenty of legal buyers here are simply careful about it.

The retail geography is the easiest in the state to describe. Euclid Avenue, which is US Highway 12 running east and west across the north side of town, holds the densest run of dispensaries, including Bloom Montana at 1446 Euclid and Top Shelf Botanicals at 520 Euclid. Apogee Gardens operates a Helena store as part of an operation that also serves Livingston, Lionheart Cannabis has a Helena location in its five-city chain, and White Pine MT and Keeper of the Green run multiple counters around the county. The walking mall on Last Chance Gulch has none of them - that is restaurants and shops.

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 July 1, 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.
