Trish Regan reports on the business of medicinal marijuana. In Colorado, the industry has sparked an infusion of capital and jobs into the weak economy, and provides needed tax revenue to the state and local governments. The documentary also details federal efforts to eradicate the weed in the mountains of eastern Kentucky (despite its legal status in 15 states and Washington, D.C., the drug remains illegal on the federal level); and the campaign against complete legalization in California.
