Well... as a half-christian, i did read all the text... the passages cited there, in the books of Micah and Ezekiel, refers about things that are completly unrelated to his interpretation concerning weed.
If we get only small quotes of the Bible, without looking at in which context they are, and what they really mean, its easy to interpret them at will, and its exactly what religion-makers does. They get a small piece of the Bible (or any "sacred" book), and interpret them in the way they wish.
