The Green Lady Dispensary sits on Amelia Drive in Nantucket’s mid-island commercial corridor, about 30 miles offshore in the Atlantic — a location that makes it unlike any other cannabis operation in Massachusetts. Because federal law prohibits cannabis from crossing federal waters or airspace to or from Nantucket, every product sold at 11 Amelia Drive must be grown, processed, extracted, and tested on the island itself. The Green Lady operates a state-of-the-art indoor cultivation facility powered entirely by LED grow lights, a supercritical CO2 extraction lab, and a commercial kitchen — all under one roof — making it the first cannabis company in the United States approved for modified on-premises compliance testing. Its Ocean Grown (OG) flower strains are Nantucket-exclusive, cultivated organically in small batches with an island microclimate that cannot be replicated on the mainland. The menu covers flower, pre-rolls, infused pre-rolls, vape pens, concentrates, edibles, drinks, wellness products, and accessories. The store opened August 11, 2019, as Massachusetts’ first off-mainland dispensary and serves both recreational adults and medical patients. The Green Lady Dispensary Nantucket suits seasonal visitors and year-round island residents who want Nantucket-exclusive small-batch cannabis from the only fully island-contained cannabis operation in the state, with daily hours through evening and an award-winning reputation.
