Welcome to Theory Wellness!

Hey, we gotta ask.

Are you 21+?

Small Batch Cannabis

Massachusetts Premium Cannabis Dispensaries


We have a deep passion for cannabis and the role it plays in improving people's lives. We’re a vertically integrated cannabis cultivation, product manufacturing, and retail company headquartered in Bridgewater, MA with retail locations in both Bridgewater (medical) and Great Barrington (medical and recreational).

Focused on small batches and unique genetics, we strive to develop a premium range of strains and 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 our approach to cannabis therapies.

Theory’s T-Pen is our flagship line of vape pen hardware, designed to work with our in-house glass CO2 cartridges. The T-Pen hardware is available in two configurations, ‘button’ and ‘buttonless.’ The T-Pen with a button has an adjustable battery, and allows the user to prime the cartridge with heat prior to inhalation, which provides a stronger vaping experience. The ‘buttonless’ T-Pens are extremely easy to operate – inhaling on the cartridge automatically turns on the device and begins the vaporizing process. Each T-Pen comes with a storage case and a USB charger.
