Mary's Medicinals is the Denver cannabis brand built on transdermal patches, founded in 2013 and still selling under the line "Science Smart. Plant Wise." The shelf runs patches, creams, compounds and sublingual oils. Since January 12, 2026, the brand has belonged to MM Brands, a Denver company led by chief executive Joe Bayern.
The patches still anchor the business. Headset counted Mary's in 802 licensed stores across 12 states in its September 6, 2026 snapshot and ranked it No. 1 in Missouri topicals and No. 2 in California topicals for August 2026.
Two-inch squares and a transdermal patent
The format is the brand. Mary's patches are 2-by-2-inch squares sold singly or in 10-packs, and the 1:1 version carries 10mg of CBD and 10mg of THC. The site bills them as heat-, sweat- and water-resistant.
Intellectual property came early. BellRock Brands described Mary's in October 2021 as a 2013 company focused on delivery methods and IP, including a U.S. patent for its transdermal technology. The same release cited BDSA data naming Mary's the best-selling cannabis brand in topicals for the first half of 2021.
The BellRock years and licensed partners
By December 2020, Mary's sat inside BellRock Brands, the Denver multistate company that also owned Dixie, founded in 2010. BellRock said at the time that its portfolio spanned nine states, 11 brands and more than 200 SKUs.
Growth ran through licensing. On December 11, 2020, BellRock signed Matrix NV, a Las Vegas producer, to make, distribute and sell Mary's and Dixie to every cannabis retailer in Nevada, starting in the first quarter of 2021. The Nevada menu covered transdermal patches, transdermal gels, topical compounds, gummies, mints and elixirs.
Maryland followed on October 21, 2021. Curio Wellness took on manufacturing and distribution of Mary's patches, a transdermal gel pen and transdermal compounds at its 34,000-square-foot facility in Timonium, with product due in the first quarter of 2022. Curio already made Dixie for the state. BellRock president Brian Jansen said both companies "share an unrelenting commitment to quality, science, and innovation."
A People's Choice cup in Michigan
The patch took hardware in 2023. At the High Times Cannabis Cup Michigan: People's Choice Edition, with results posted July 11, 2023, the 1:1 CBD:THC transdermal patch won first place in the AU Topicals + Tinctures + Capsules + Sublinguals category.
The brand's own product page goes further, listing the same patch as a winner at both the 2023 Michigan and SoCal High Times Cups. It also lists the patch in California, Colorado, Michigan, Missouri, Nevada, Ohio, Vermont, Illinois and Canada.
Patches sorted by cannabinoid
The 2026 patch lineup splits by compound. Single-cannabinoid patches cover THC in sativa and indica versions, CBD, CBN, CBG and THCa. The 1:1 CBD:THC patch sits alongside a three-cannabinoid FORMULA patch and a live rosin patch.
The topical side adds three creams, a 1:1 CBD:THC transdermal compound, a 1:1:1 FORMULA compound and two further topicals in 1:1 and CBD-only versions. Headset's top seller for August 2026 was the CBD/THC/CBN 2:3:1 FORMULA transdermal patch, ahead of a 1:1 cream and a 1:1 compound balm.
Sublingual oils make up the consumable shelf. They come in 1:1 and 30:1 CBD-to-THC ratios, a 2:1:1 THC-CBD-CBN blend, THC-only versions and two FORMULA oils at 2:2:1:1 and 4:4:2:1:1. Headset put tinctures and sublinguals at 25.5% of August 2026 sales, with topicals at 74.5%.
Who owns Mary's Medicinals now
BellRock Brands was placed in receivership in March 2024. On January 12, 2026, Denver's KEY Investment Partners bought the BellRock portfolio out of receivership and folded it into a newly formed company, MM Brands. KEY, founded in 2018 by founding partner Jordan Youkilis, manages more than $50 million.
The deal covered six brands: Mary's Medicinals, Mary's Nutritionals, Mary's Tails, Dixie Elixirs, Rebel Coast and Défoncé. Youkilis called Mary's "a powerhouse brand known for its science-driven approach to transdermal patches, topicals and tinctures," and framed the purchase as "the perfect deal at the perfect time" given consumer interest and the prospect of federal rescheduling.
Bayern is a former president and CEO of Curaleaf Holdings, with earlier executive roles at VOSS of Norway and in the creation of Dr Pepper Snapple Group. MM Brands runs an asset-light model, and KEY counted 11 states at the close, among them California, Michigan, Missouri and Maryland.
StateHouse in California and the 2026 map
California got a fresh production partner on May 1, 2026. MM Brands signed StateHouse Holdings, through its licensed subsidiaries, to manufacture and distribute Mary's Medicinals and DIXIE in the state. StateHouse CEO Jim Scott called them "iconic brands."
The August 2026 numbers show the reach. Headset tracked 297 California stores carrying Mary's and 125 SKUs at an average price of $28.45. On top of the No. 1 spot in Missouri topicals, the brand ranked No. 2 in Michigan topicals, Michigan tinctures and sublinguals, and Missouri tinctures and sublinguals.
