Small Batch Cannabis

Massachusetts Premium Cannabis Dispensaries


Theory Wellness has paused the sales of cannabis-infused vaporizers and associated devices following Governor Baker’s recent directive. All other cannabis-related products will continue to be available at our locations. We look forward to working with the State of Massachusetts to safely and responsibly return these products to the regulated cannabis market. Please note that we do not have any concerns regarding the safety of products we have sold to date, and will not be accepting returns for previously purchased products.


Our store is now open from 8 AM until 10 PM, seven days a week!

Pre-order at this location will now be available from 7:45 AM until  7PM.

If you are looking to learn more about our current limits and product availability, please check our PDF menu above. We update the menus throughout the day!

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.
