The House of Mary Jane sits on James Couzens Freeway in Detroit’s northwest side, close to the Huntington Woods and Palmer Park borders — a location that draws medical patients from the surrounding Eight Mile–Wyoming, Palmer Park, and Bagley neighborhoods. The provisioning center has been serving Detroit medical cannabis patients since opening and runs a loyalty-friendly deal structure: patients get 10% off for leaving a verified review on Google, Weedmaps, Leafly, or Yelp; referrals earn a free eighth for both parties; birthdays bring 10% off; and veterans receive 5% off Thursday through Saturday. Home delivery is available for Michigan medical cardholders with a $50 order minimum for patients within five miles and a $100 minimum beyond that, with a free gram for first-time delivery patients.

The House of Mary Jane is best suited to established Detroit-area medical cannabis patients who want a consistent neighborhood provisioning center with a delivery option and a strong discount program. The store carries flower, edibles, and concentrates, with staff known for product knowledge and patient education. James Couzens Fwy connects directly to I-96 and the Lodge Freeway interchange nearby, making it accessible from much of northwest Detroit and the inner suburbs.
