The Greenfaith Ministry is a supporter of the THC Ministry.
"The THC Ministry, founded by Roger Christie from the Religion of Jesus Church, is a religion which considers cannabis to be a sacrament. Members base their practices on what they see as an eclectic mixture of ancient wisdom, modern science, and the enlightening and healing properties of cannabis sacrament. Its mission includes "liberating the Cannabis plant and the minds of those who do and of those who do not revere it," and is actively involved in the legal and social discussions surrounding cannabis use in society." - https://en.wikipedia.org/wiki/THC_Ministry
