Sister Kate lights a joint at Sisters of the Valley on April 18 near Merced, Calif.
The self-ordained "weed nuns" are on a mission to heal and empower women with their cannabis products. The sisterhood stresses that its seven members, despite the moniker, do not belong to any order of the Catholic Church. They consider their Holy Trinity to be the marijuana plant, specifically hemp.
Sister Kate, whose real name is Christine Meeusen, adopted the nun persona after she took part in an Occupy Wall Street protest in 2011 dressed as a Catholic nun, a look that led her to be known by protesters as "Sister Occupy."
"We've gotten a few hate calls but, by and far, the Catholics understand what we're doing," she said.

The second round of the Bottle Kicking gets underway over the Hare Pie Hill on April 17 in Hallaton, England.
The Hare Pie Scramble and Bottle Kicking events form an ancient custom that dates back to the early eighteenth century, and one of the oldest in British History.

The second part, the Bottle Kicking sees two rival villages, Hallaton, and neighboring Medbourne attempt to carry a 'bottle' which is actually a keg of beer, from the Hare Pie Bank, and get it across a boundary stream for their own village.

A North Korean medium-range missile exploded seconds after it was launched on Sunday, U.S. officials said.
The White House believes it did not involve an intercontinental ballistic missile. The North regularly launches short-range missiles, but is also developing mid-range and long-range missiles meant to target U.S. troops in Asia and, eventually, the U.S. mainland.
The failed launch came a day after one of the biggest North Korean propaganda events of the year-- celebrations of the 105th birthday of late North Korea founder Kim Il Sung, the current leader's grandfather.
