Frosteez is the Billings flagship of one of Montana’s most decorated independent cannabis chains, operating out of Building 3 on Jellison Road in a commercial cluster just off the Lockwood interchange — about ten minutes east of downtown Billings. The operation has been running at this address since 2019 under the former Sunnyside Medicals name, and the rebrand to Frosteez brought a significant expansion: five locations now across Billings, Great Falls, Laurel, Lockwood, and Missoula, with two more coming to Sidney and Plentywood. What sets this location apart is the fully vertical, in-house operation — Frosteez grows its own flower, runs its own extraction lab for artisan concentrates, and produces all edibles in-house, including ice cream, gummies, and infused sugars. The product menu spans flower, pre-rolls, concentrates, cartridges (distillate, live resin, live rosin, and melted diamond), edibles, accessories, and rotating seasonal specialties. The Billings location was named Best Dispensary in Montana for both 2023 and 2024.

If you’re looking for a seed-to-sale cannabis shop on the east side of Billings with award-winning product, an in-house lab, and the kind of budtender knowledge that only comes from watching a product go from grow room to shelf — Frosteez on Jellison Road has been the standard-setter in this market for years. Online ordering available at frosteez.com; open seven days a week.
