JAR Cannabis Co.’s recreational storefront at 11 Storm Drive in Windham is one of the most consistently praised dispensaries on the Route 302 corridor — founded by two of Maine’s very first medical marijuana caregivers in 2012, with caregiver operations beginning as early as 2011, JAR opened its first medical storefronts in 2019 and launched adult-use retail in 2021. The Windham operation represents the core of a multi-location Maine cannabis company that also serves Portland, South Portland, and Newry. JAR is vertically integrated: cultivation, processing, and retail all run in-house, with strains selected specifically for their terpene and cannabinoid profiles and grown using organic practices. Leafly reviewers call it “the bar of excellence in Maine cannabis” and “the best in the Windham area by the largest of margins,” with particular praise for flower quality, consistency, staff knowledge, and the variety of strain offerings. A separate JAR medical storefront serves registered patients from a different Windham address. The recreational store at 11 Storm Drive is open daily from 8 AM to 8 PM — among the earliest opening hours on the Route 302 corridor. Products span flower, pre-rolls, edibles, drinks, vape pens, and concentrates, with in-house JAR Co. products alongside curated Maine retail brands. Note that the parking lot exits can be slow during peak hours per multiple reviewer mentions. JAR Cannabis Co. suits recreational adults 21-plus and medical patients across Windham, North Windham, Raymond, Gorham, Standish, and the Sebago Lakes region who want one of Maine’s longest-running organic cultivators with vertically integrated production and a deep terpene-forward strain roster.
