Mary Jane Rathbun, born in 1922 in Chicago, grew up in a strict Irish Catholic household in Minneapolis. Defiant from a young age, she left home as a teenager and worked as a waitress for most of her life. Activism was always part of her identity — she campaigned for miners’ rights and abortion access before moving to San Francisco during World War II.

The Birth of “Brownie Mary”

In the 1970s and 1980s, Rathbun began baking cannabis‑infused brownies. She distributed them to AIDS patients at San Francisco General Hospital, calling them her “kids.” Her grandmotherly appearance and compassion made her a beloved figure in the community.

Despite multiple arrests, she became a symbol of resistance against prohibition. Her mugshots and courtroom appearances only amplified her folk‑hero status.

Activism and Legal Reform

  • Arrests: Rathbun was arrested three times, each time drawing national attention and sympathy.
  • Proposition P (1991): She helped pass San Francisco’s resolution supporting medical cannabis.
  • Proposition 215 (1996): Alongside Dennis Peron, she was instrumental in passing California’s Compassionate Use Act, the first state law legalizing medical marijuana.
  • Cannabis Buyers Club: She contributed to establishing the first medical cannabis dispensary in the U.S.

Cultural Impact

Brownie Mary’s activism:

  • Humanized cannabis reform by linking it to compassion and patient care.
  • Inspired researchers to study cannabinoids in HIV/AIDS patients.
  • Shifted public perception, showing cannabis as medicine rather than vice.
  • Cemented her as a folk hero of cannabis culture, celebrated annually on “Brownie Mary Day” (August 25, 1992, declared by San Francisco officials).

Legacy

Mary Jane Rathbun passed away in 1999, but her legacy lives on in every medical cannabis program across the U.S. and beyond. She remains a symbol of grassroots compassion, proving that one person’s kindness can spark a movement.

Brownie Mary’s story is not just about cannabis — it’s about compassion, courage, and the power of grassroots activism. Her brownies were more than medicine; they were symbols of dignity and care during the darkest days of the AIDS crisis. Today, every medical cannabis law traces its roots back to her kitchen.
