SeaWeed Co.’s Portland location at 23 Marginal Way, Suite 7 was the first recreational cannabis storefront to open in the city in 2021, establishing the Maine-owned brand’s presence in Portland’s Bayside neighborhood — nestled between the Downtown and East Bayside districts, sharing a parking lot with Chipotle and positioned just off I-295 at Exits 6A/6B for easy access from anywhere in Greater Portland. The store carries SeaWeed Co.’s full signature menu of flower, pre-rolls, edibles, concentrates, beverages, and CBD products, with a particular specialty in live resin extracts, alongside locally produced Maine cannabis art, accessories, and branded merchandise. The staff — referred to as “mermaids” in the brand’s playful coastal voice — approach every visit as a guided, education-first experience tailored to the individual customer’s goals, whether they know exactly what they want or are still learning. Delivery is available through seaweedmaine.com alongside in-store pickup. The Bayside location puts customers within minutes of the Old Port, Portland Museum of Art, Deering Oaks Park, USM, and the Maine Narrow Gauge Railroad, making it a natural stop for both locals and visitors exploring the city. SeaWeed Co. Portland suits recreational adults 21-plus across Portland’s Bayside, Downtown, East Bayside, and the broader Greater Portland area who want Portland’s original recreational dispensary with award-winning store aesthetics, live resin expertise, and a coastal Maine brand identity built around education and community.
