Stem sits at 124 Washington Street in the heart of historic downtown Haverhill — Haverhill’s first adult-use cannabis dispensary, opened by social equity licensee Caroline Pineau in a 6,400-square-foot Washington Street building that dates back to the city’s mill era. The store operates a few steps from the Merrimack River and walking distance from a cluster of bars, cafés, and restaurants along Washington Street, making it a natural stop before or after dinner in Haverhill’s growing downtown scene. As an independently owned social equity operation, Stem has used its standing to push for reinvestment in the city: in 2025 the business was awarded a $500,000 Massachusetts Cannabis Social Equity Grant to fund renovation of the building’s upper floors and rooftop into what could become one of the state’s first on-site cannabis consumption lounges. The dispensary carries a hand-curated menu of flower, pre-rolls, vape pens, edibles, concentrates, tinctures, and topicals — sourced from Massachusetts producers including Cape Cod, Highmark, Cultivators Classic, and Erva — refreshed with daily deliveries. The “Stem Wayfinder” service offers personalized one-on-one consultations by appointment for customers who want more than a quick floor transaction, and the Gratitude loyalty program rewards regulars. Stem Haverhill is the right stop for recreational adults 21+ across Haverhill, Methuen, Merrimac, Georgetown, and the greater Essex County and Merrimack Valley area who want a locally rooted, independently owned downtown dispensary with a strong community identity and walkable access from the MBTA Haverhill commuter rail station.
