I saw that article 2 days ago in a free copy of a newspaper, given to people on the street.... The full (very small) article was:
"US growers produce nearly $35bn worth of marijuana a year, making it America's largest cash crop, bigger than corn and wheat combined, says a report by public policy analyst Jon Gettman, who said California, Tennessee, Kentucky, Hawaii and Washington grow $1bn worth each".......I couldn't believe the numbers!!! That's a lot of weed guys!!!!!
