Haha, what religion does to a person. You do understand pot is legal is several places, and possession is tolerated in much of the Western world. Right?
It doesn't have anything to do with religious affiliation. I know several Atheists who absolutely hate the idea of pot being legalized. Almost every person I know who smokes pot are complete deadbeats. They look like idiots, sitting there with a retarded smirk on their face with their eyes half shut. From personal experience and witnessing, it DOES affect motivation whether or not people want to believe it.
However, I'm not entirely concerned about being legal because:
1) It probably won't be.
2) Those who smoke pot don't have an issue getting it. Legalizing it wouldn't make a huge difference.
