Hemp is a variety of Cannabis with extremely low THC levels and high tensile strength. It can be used to make a variety of products, and is a versatile, useful, and renewable resource. With the legalization of marijuana in several US states, and a growing acceptance for weed, will hemp come back into use? There are currently legal restrictions on hemp, but backers are trying to lift the bans so hemp can be used for housing insulation. Using hemp to make products could lessen the need to use other resources that are quickly being depleted, such as wood, and may be an environmentally friendlier alternative to some synthetic materials that are not biodegradable.
