Nuns living in a remote area near Yosemite National Park are making a name for themselves around the world due to their devotion to cannabis. The self-proclaimed "Sisters of the Valley" are often called "The Weed Nuns." The mission of their sisterhood is to get the most amount of plant-based medicine to the most amount of people around the world, "while doing it in a manner that is aligned with our values of compassionate activism, spirituality and service. Their vision is to "bridge the gap between Mother Earth and her suffering people, and open up the world to the healing powers of nature’s gifts."

"We're not ditzy stoner nuns," Sister Sophia Maya Costaras said. "We try to say that to folks. we're scholars, we're intellectuals, we're spiritual, we walk our walk, and we walk it very fluidly with everyone." Their story has been featured across the globe, from Rolling Stone Magazine to the BBC. These nuns are not part of any official, organized religion. However, they wear traditional habits historically worn by sisters in the Roman Catholic Church.
