NORTH CAROLINA: While cooking oil was the main topic of Dean Price’s presentation to the school board, another key component to biofuel would be the growth of farm crops that could supply fresh oil.
Back in 1900, hemp was the biggest crop in the state, Price said. Then in the 1930s, confusion over the differences between hemp and its cousin marijuana led to laws outlawing hemp.
The component in marijuana that produces a high is known at tetrahydrocannabinol (THC). While that plant has a good amount of THC, hemp has only a trace in its leaves.
