I'll begin by saying that in NO way do I advocate its use (maybe for medicinal purposes, but that's a different debate). I saw a report on MSNBC about this agricultural "crop" and was stunned to see that it makes more than corn and wheat, combined.
I post this for informational purposes only. Again, I don't advocate its use.
