Genesis 1:29: And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for meat

Notice that God said, "I have given you every "herb bearing seed," and "to you it shall be for meat"! It said it was given to man for "food"! He didn't tell man to "dry it out, roll it up, and smoke it," FOOL! Your "body" is the "temple of the Holy Ghost," and the Lord said:
1 Corinthians 3:16-17: (16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?

17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.)
