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. -- Genesis 1:29
God gave us every plant for food. What about Canabis sativa? Is it okay to eat (or smoke) that plant? How about the opium poppy (Papaver somniferum), coca plant (Erythroxylum coca), or the peyote cactus (Lophophora williamsii)? Did God give us these plants to eat too? It would seem that he did, since there are no exceptions given in Genesis 1:29.
