As for the Bible, Jesus loved the herb, the boys were natty dreads!

And the earth brought forth grass and herb yielding seed after its kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good. (Genesis 1:12)

"I will take my rest and I will consider in my dwelling place like a clear heat upon herbs, and like a cloud of dew in the heat of harvest. For afore the harvest, when the bud is perfect and the sour grape is ripening in the flower, he shall cut off the sprigs with pruning hooks and take away and cut down the branches. (Is. 18:4-5)

Jesus said about drugs and morality- "Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man." (Matt. 15:11)

"One believeth that he may eat all things. Anotherâ?¦eateth herbs. â?¦ Let us not, therefore judge one another any more: but judge this rather, that no man put a stumbling block or an occasion to fall in his brother's way."
(Epistle of St. Paul: Romans 14: 2,3,13,14,17)

Did you know if we didnt use artificial chemicals in our shampoos we'd all have dreads?
