Here’s what you need to know.

At Theory, we cultivate cannabis in very controlled environments to create the ideal conditions that allow our plants to thrive. By controlling the humidity, temperature, lighting, CO2 levels, nutrients, airflow, and pruning techniques, Theory is able to allow each strain of cannabis to reach its maximum genetic potential. Additionally, we implement strict and extensive sanitation protocols to ensure that no potential contaminants ever enter our facility.

Third parties independently test all products that are sold at recreational cannabis dispensaries in Maine. They’re screened for things like molds, heavy metals, and other contaminants that might cause adverse reactions. All products are affixed with a label that will reflect the testing information for every product you buy.

Cannabis Strains

Theory carries a wide variety of marijuana strains. Each strain is labeled on the spectrum from sativa to indica. We also carry CBD rich strains. Many strains are hybrids, meaning they are a combination of the three main types of strains explained below.

Sativa strains of cannabis are naturally occurring in tropical, equatorial areas of the world such as southeast Asia and Africa. They may provide an increase in energy and focus or an elevated mood, and are generally recommended for daytime use.
Indica strains are naturally occurring in mountainous, colder climates. They may provide a calming sense of relaxation in the body and are generally recommended for evening use.
CBD is a non–psychoactive compound that may offer increased relaxation in the body.


Our Customer Service agents are available to help between 9 AM – 6 PM ET 7 days a week! Feel free to email us at [email protected], give us a call, or use our chat feature in the bottom right hand corner of our website.
