ABOUT THEORY

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.

T-Pen

  • MORE DETAILS

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.
