Good news for those interested in building with hempcrete in the US. Recent laws are making it much easier to obtain legal hemp for making hempcrete. Some hempcrete mixes turn almost as hard as stone.
“State legislatures have taken action to promote industrial hemp as an agricultural commodity in recent years. A wide range of products, including fibers, textiles, paper, construction and insulation materials, cosmetic products, animal feed, food, and beverages all may use hemp. The plant is estimated to be used in more than 25,000 products spanning nine markets: agriculture, textiles, recycling, automotive, furniture, food/nutrition/beverages, paper, construction materials and personal care.
While hemp and marijuana products both come from the cannabis plant, hemp is typically distinguished by its use, physical appearance and lower concentration of tetrahydrocannabinol (THC). Hemp farmers and producers often grow the plant for the seeds and stalk. The plant is cultivated to grow taller, denser and with a single stalk. Marijuana, grown for the budding flowers, tends to be grown shorter, bushier and well-spaced.
At least 30 states passed legislation related to industrial hemp. Generally, states have taken three approaches: (1) establish industrial hemp research and/or pilot programs, (2) authorize studies of the industrial hemp industry, or (3) establish commercial industrial hemp programs. Some states establishing these programs require a change in federal laws or a waiver from the DEA prior to implementation.
At least 16 states have legalized industrial hemp production for commercial purposes and 20 states have passed laws allowing research and pilot programs. Seven states—Colorado, Kentucky, Maryland, Minnesota, North Dakota, Rhode Island and Virginia—have approved the creation of both pilot/research and commercial programs. Many of the states that have legalized hemp cultivation for commercial purposes specify that state law does not allow for violation of federal law. States including California, Indiana, Kentucky, Minnesota, Montana and Virginia have established a framework for regulating commercial hemp but still consider hemp illegal outside of research programs unless federal law changes.”

Special thanks to Dave for this update. He says there is a ready supply of legal hemp hurds in the US, Colorado in particular. “States are in various degrees of what you can or cannot do. Colorado is pretty much whatever you want to do as long as the industrial hemp is less than .3%THC.”
