Genesis 1:29-31 29Then God said, "Behold, I have given you every plant yielding seed that is on the surface of all the earth, and every tree which has fruit yielding seed; it shall be food for you; 30and to every beast of the earth and to every bird of the sky and to every thing that moves on the earth which has life, [U]I have given every green plant for food[/U]"; and it was so. 31God saw all that He had made, and behold, it was very good. And there was evening and there was morning, the sixth day.

1 Timothy 4:1-4 1But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons, 2by means of the hypocrisy of liars seared in their own conscience as with a branding iron, 3men who forbid marriage and [U]advocate abstaining from foods which God has created to be gratefully shared in by those who believe and know the truth. 4For everything created by God is good, and nothing is to be rejected if it is received with gratitude; [/U]

Not really sure if the second verse is refering to cannabis, but it sounds like a possibility to me. Marijuana has been illegal in the US for only 68 years. It has been used by many cultures around the world for about 5,000 years. Hemp, and specifically Cannabis sativa, is an amazing plant. It can be used for fuel, textile, food, and medicine, among other things. God created hemp for a reason. Who knows, maybe God did smoke cannabis.
