Women in Medical Cannabis: From Underground Caregivers to Clinical Pioneers

Long before clinical trials, ballot initiatives, or dispensary shelves, a handful of women quietly built the foundation of medical cannabis in America. Their tools were brownies, gardens, courtrooms, and eventually, medical degrees.

The history of women in medical cannabis is often told as a footnote to a larger political story, a tug-of-war between federal prohibition and state reform movements. But underneath that narrative runs a quieter thread: the sustained, often dangerous work of women who pushed cannabis toward the mainstream when doing so could cost them their freedom. Women have been driving medical cannabis advocacy for decades, from informal caregiving to peer-reviewed science, and their contributions deserve a clear-eyed look.

Brownie Mary: Where Compassion Became a Political Act

In the early 1980s, a retired cafeteria worker named Mary Jane Rathbun began baking cannabis-laced brownies in her small San Francisco kitchen and carrying them through the AIDS wards of San Francisco General Hospital. She asked nothing in return. Patients called her “Brownie Mary,” and for men who were too nauseated to eat, too exhausted to fight, and largely abandoned by the medical system, her visits were a lifeline.

She was arrested twice. Each time, the public response was overwhelming. Rather than ending her work, the arrests amplified it, drawing press coverage and turning a grandmother with a baking sheet into the unlikely face of the medical marijuana movement. San Francisco declared “Brownie Mary Day” in her honor and the Board of Supervisors passed a resolution supporting medical cannabis use. That local momentum fed directly into California’s Proposition P in 1991 and eventually into Proposition 215 in 1996, a landmark moment in cannabis legalization history and the nation’s first successful statewide medical cannabis ballot initiative.

Rathbun’s power came not from policy expertise but from moral clarity. She showed the public that medical cannabis users were not criminals. They were her patients, and she was their caregiver.

Valerie Corral: Building a System, Not Just a Garden

In 1973, Valerie Corral survived a car accident that left her with a severe seizure disorder. Conventional medications helped only partially. After experimenting with cannabis, she found it dramatically reduced the frequency and intensity of her seizures. What began as personal necessity became her life’s work.

Corral’s medical-necessity defense following early arrests laid important legal groundwork, demonstrating that cannabis could be framed not as recreational use but as genuine therapeutic need. In 1993, she and her husband Mike co-founded the Wo/Men’s Alliance for Medical Marijuana (WAMM) in Santa Cruz, a member-run collective that grew cannabis for patients with serious illnesses, including many in hospice care.

Corral co-authored Proposition 215, helping draft the language of what would become California law. WAMM’s model was different from a dispensary: it was a community, built on the idea that patients deserved dignity and participation in their own care. When federal DEA agents raided WAMM’s garden in 2002 and destroyed the plants, patients and local officials showed up in protest. The raid backfired publicly, galvanizing support and reinforcing WAMM’s moral authority. WAMM later evolved into WAMM Phytotherapies, a licensed cannabis company that still prioritizes patient access and social equity.

Corral didn’t just advocate for medical cannabis. She built an institution around it.

Dr. Bonni Goldstein: From Emergency Medicine to Cannabinoid Science

By the time medical cannabis had legal footing in California, it still lacked clinical credibility. That gap is part of what drew Dr. Bonni Goldstein away from pediatric emergency medicine and toward cannabinoid therapeutics. Over the course of her career, she has evaluated thousands of patients, with a particular focus on autism and treatment-resistant epilepsy in children.

Her work represents the transition from grassroots cannabis advocacy to evidence-based practice. By documenting patient outcomes, contributing to peer-reviewed literature on cannabinoid therapeutics, and educating other clinicians, Goldstein helped establish that cannabinoid medicine deserves the same rigorous scrutiny as any other therapeutic area. She’s part of a broader cohort of women scientists, including researchers like Michelle Glass and Saoirse O’Sullivan, whose work in cannabinoid pharmacology is now shaping how physicians understand the endocannabinoid system.

What Research Reveals About Women in Medical Cannabis

Women in medical cannabis have shaped the field as patients, caregivers, legal advocates, and clinical researchers — and the data increasingly reflects their outsized influence. A peer-reviewed study on gender differences in medical cannabis use found that women are more likely to use cannabis for pain, anxiety, and sleep disorders, and that many report meaningful symptom relief. The medical cannabis history documented in studies like this one reflects a consistent pattern: women have been disproportionately represented among patients while being undercredited as advocates and researchers.

Women also show different patterns of use and different sensitivity to cannabinoids compared to men, a distinction that researchers are only beginning to explore in depth. Understanding how women experience medical cannabis differently isn’t a niche concern. It’s a core question for anyone designing clinical protocols or patient education programs.

A Legacy Still Being Written: Women Shaping Medical Cannabis Today

The arc from Brownie Mary’s hospital visits to Dr. Goldstein’s clinic is not a straight line. It’s a series of overlapping efforts by women who refused to accept that compassion and evidence were incompatible with cannabis. They worked through kitchens, courtrooms, collectives, and clinical settings because the need was real and no one else was stepping up.

Today, women in medical cannabis continue to shape the field as researchers, physicians, advocates, and policymakers. The work of this next generation is built, whether they know it or not, on the foundations these women cannabis pioneers laid. Medical cannabis didn’t emerge from a committee. It emerged from people who cared enough to risk something for it, and many of the most important were women.
