The dependency, adoration, and excitement about being around weed makes some people seem devoted to it. I have watched them sort the seeds, examine the weed meticulously, hold it to the light, and roll it carefully like a priest performing a sacred ritual.
I have also noticed some stoners try to get others to convert to weed. They claim it heals miraculously; they claim it recues them from the insanity of the world out there. In short, it becomes their savior.
Many even make sacrifices for weed, giving up interests, losing jobs, spending money on weed that should go to bills.
Like Jesus Freaks, they wear t-shirts with images of their savior, buy weed necklaces, make weed memes, and exclude people from their social circles that haven't converted to weed.
Before the name-calling begins, I add that they also get angry when someone questions their devotion, attacking anyone who disagrees and saying that person is stupid and evil, and should be silenced. Like all fundamentalists do.
