Hemp has always been a cash crop. Fuel may be the most important product you can get from hemp for our growing energy needs, but there are literally thousands of different products you can make from hemp. From clothing, to makeup, to biodegradable plastics, it's pretty much a miracle plant.

It has 4x the yield of tobacco, is incredibly resilient to changes in environment and it grows very quickly. I would argue that hemp would be a staple in any sustainable society. It's really a shame that it's illegal in the US.
