American Hemp examines what this new domestic crop can be used for, what makes it a superior product, and what made it illegal in the first place; the book also delves into the many health and medical benefits of the plant. Hobbs weighs in on how hemp can improve existing industries, from farming to energy to 3D printing, plus how it can make a serious impact on climate change by removing toxins from the soil and by decreasing our dependence on plastics and fossil fuels.
