If governments and corporations really wanted to help the environment and create more sustainable housing, I can guarantee you that the whole world would be using Hempcrete right now. Unfortunately, It seems that they are too concerned with keeping their very profitable system that they fear changing things.
Growing industrial hemp was illegal in the United States after 1970 because the industrial plant and marijuana were considered to be the same, when in fact they are different varieties of Cannabis. In recent years, some states have changed their laws, allowing farmers to start growing industrial hemp, which is used in everything from clothing to nutritional products to building materials. Oregon grower Cliff Thomason says growing and processing hemp was stymied because it was illegal, but now a knowledge base for best uses can grow, along with the plants.
