Our Story
PG County Based Maryland Cannabis Dispensary
Mary & Main’s journey began with Hope Wiseman, a pioneering Black woman who first embraced cannabis during her college years to manage severe anxiety. Her experience was life-changing, providing critical relief when she needed it most.
When Hope returned home, she was confronted with the reality that many people in her community were being penalized for using the same plant that had helped her. In response, Hope and her mother, Dr. Octavia Wiseman, decided to create change.
Together, they envisioned a welcoming space where the community could safely access cannabis, learn about its benefits, and receive thoughtful support without judgment. That vision became Mary & Main, a family-owned, Black-owned dispensary rooted in Capitol Heights, Maryland.
Today, Mary & Main represents their dedication to community care, education, wellness, and equitable access. Located near Central Avenue, Addison Road Metro Station, Fairmount Heights, Coral Hills, and the greater Prince George’s County and DMV area, Mary & Main is more than a place to shop. It is a space built to make people feel informed, supported, and at home.

Frequently Asked Questions.
New to Mary & Main, visiting as a medical patient, or just trying to understand Maryland’s rules? Start here.
Visit the Full FAQ Page01 Do I need a medical card to make a purchase?
No. As of July 1, 2023, adults age 21 and older may purchase from licensed Maryland dispensaries without a medical card.
Medical patients are welcome with a valid, unexpired government-issued photo ID. What we actually verify is your active certification in the state system — so even if your physical MCA card shows an expired date, you’re still good to shop as long as your certification has been renewed. Registered medical patients receive priority service and are exempt from cannabis tax, while adult-use purchases are subject to Maryland’s 12% cannabis sales tax.
