Small Batch Cannabis

Massachusetts Premium Cannabis Dispensaries

CHICOPEE GRAND OPENING: Saturday, February 29th at 9AM

We couldn’t be more excited to announce that we are officially opening our doors this coming Saturday at 9AM.

Sign-up below to be the first to see our opening day menu!


We have a deep passion for cannabis and the role it plays in improving people’s lives. Here at Theory, we cultivate cannabis and produce a wide variety of extracts and infused products at our Bridgewater, Massachusetts facility. We also have retail locations in both Bridgewater (medical) and Great Barrington (medical and recreational), where our customers can learn about cannabis and purchase our products.

Focused on small batches and unique genetics, we strive to develop a premium range of flower, concentrates, and infused products for consumers in Massachusetts. In doing so, we commit ourselves to constant reinvention and self-scrutiny, working with and listening to each other, to further improve and enhance your cannabis experience.




Theory carries a variety of staff selected, high-quality Glassware, including American-Made pieces from local artists at Witch Dr. located in Salem, Ma, along with many other options from Grav Labs and the Jane West Collection. Stop by anytime to discuss our selection in more detail with one of our cannabis consultants. Our staff looks forward to recommending the ideal glassware for your needs.
