I too am surprised to see such an article on CNN.

The one thing it doesn't touch on is the cost we have incurred as a nation by making it illegal. We have seen this before with prohibition, it didn't stop people from drinking it just made better criminals. Once we legalize it we can stop spending money fighting it and start taxing it!

Of course the funny thing will be watching all the farmers in Illinois plow down their corn fields to crow weed! Yes I am aware of what it takes to grown corn in terms of resources, time, and cost and at the current market rate for weed those fields would be plowed under in record time!
