Diem Cannabis occupies a remodeled automotive garage on Grafton Street in Worcester’s Canal District — just off Exit 18 on I-290, within walking distance of Union Station, the DCU Center, and Polar Park, home of the Worcester Red Sox. The location opened in June 2020 as Diem’s first Massachusetts store, originally based out of Oregon, and has since grown to include a second location in Lynn. The Canal District placement puts it in one of Worcester’s most active neighborhoods, with on-site dedicated parking making it easy to reach from across the city and from nearby communities including Shrewsbury, Auburn, Millbury, Grafton, and Holden. Diem carries a full recreational menu covering flower, pre-rolls, vaporizers, edibles, concentrates, topicals, and tinctures, available for in-store browsing or online ordering with pickup typically ready in 10–15 minutes. Debit, credit, cash, and DutchiePay are all accepted, with two on-site ATMs. The Diem Rewards loyalty program runs across both Massachusetts locations. Diem Worcester suits recreational cannabis shoppers throughout central Worcester County who want one of the latest-closing dispensaries in the market — open until 11 PM six days a week — with a polished Canal District setting and strong Google ratings.
