What gives me pause is that the government was able to ban Cannabis in the first place. It is a God given right and is protected under the First and Ninth amendments to the U.S. Constitution as well as the Bible.
"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 King James
"...(God) Who made the earth for you an expanse and made for you therein paths and sent down water from the cloud; then thereby We have brought forth many species of various herbs. Eat and pasture your cattle; most surely there are signs in this for those endowed with understanding." Quran 020.053-054 Translation by M H Shakir
There is a phrase in almost every ancient religious book that specifies that man has the right to 'use all of the herbs of the earth'.
