Montana dispensaries sold $277.7 million of cannabis in the first ten months of 2026, state data shows. Adult-use sales rose about 4% — while medical sales fell roughly 16%.

Montana's legal cannabis market sold $277.7 million worth of product in the first ten months of 2026, according to the Montana Department of Revenue's cannabis sales reports — and nearly all of the growth came from the adult-use side of the market.

Combined sales for January through October 2026 totaled approximately $277.7 million. Adult-use purchases accounted for $251.0 million of that, roughly 90 cents of every dollar. Medical sales made up the remaining $26.7 million.

Montana cannabis sales: $277.7M in Jan-Oct 2026, $1.55B since 2022, adult-use about 90% of sales, $267.8M estimated state tax

The growth belongs to adult-use alone

Against the same ten months of 2025, the combined market grew just 1.8%. The split underneath is wider: adult-use sales rose about 4.1% year over year, while medical sales fell roughly 16%.

The figures show a widening divide inside Montana's market: adult-use sales keep growing while medical sales contract — and with recreational purchases now at roughly 90% of reported sales, the market that opened on January 1, 2022 runs overwhelmingly on adult-use.

Montana adult-use vs medical sales split: $1,286.1M vs $265.5M since 2022; $251.0M vs $26.7M in Jan-Oct 2026

$1.55 billion since the market opened

Since adult-use sales began in January 2022, Montana's reported cannabis sales total $1,551,649,271 — $1.29 billion of it adult-use and $265.5 million medical. The state figure counts sales from January 2022 onward; Montana's older medical program sales before that date are not included.

The department estimates approximately $267.8 million in state adult-use and medical cannabis taxes over the same period — $257.2 million from the 20% adult-use tax and $10.6 million from the 4% medical tax. Local-option taxes are calculated separately, from actual collections. For the first ten months of 2026 alone, the estimated state tax is about $51.3 million — an estimate calculated from estimated sales, not a collections figure.

A steady $28 million a month

October 2026 sales were $28.5 million, up slightly from September's $28.1 million and roughly flat against October 2025. The year's strongest month was July, at just under $30.0 million.

One caution applies to every figure above: the Department of Revenue labels these figures estimates — dispensaries file quarterly, so monthly numbers are revised — and reported monthly sales may include discounted purchase prices, which can differ from the statutory retail price used to calculate cannabis taxes. Actual tax collections are tracked separately.
