A mixture of fiberglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles.[37] The choice of which bast fiber to use is primarily based on cost and availability. Various car makers are beginning to use hemp in their cars, including Audi, BMW, Ford, GM, Chrysler, Honda, Iveco, Lotus, Mercedes, Mitsubishi, Porsche, Saturn, Volkswagen[38] and Volvo. For example, the Lotus Eco Elise[39] and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).[40]
Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.[46]
Hemp seeds are one of the best sources of plant-based protein and GLA and have a wide variety of health benefits, including their ability to improve heart health, stimulate digestion, build muscle mass, eliminate insomnia, treat anemia, and aid in weight loss. They also help to stimulate metabolic activity, boost the immune system, reduce symptoms of menopause and menstruation, improve skin and hair health, and build stronger bones.
Hemp is considered by a 1998 study in Environmental Economics to be environmentally friendly due to a decrease of land use and other environmental impacts, indicating a possible decrease of ecological footprint in a US context compared to typical benchmarks.[65] A 2010 study, however, that compared the production of paper specifically from hemp and eucalyptus concluded that "industrial hemp presents higher environmental impacts than eucalyptus paper"; however, the article also highlights that "there is scope for improving industrial hemp paper production".[66] Hemp is also claimed to require few pesticides and no herbicides, and it has been called a carbon negative raw material.[67][68] Results indicate that high yield of hemp may require high total nutrient levels (field plus fertilizer nutrients) similar to a high yielding wheat crop.[69]
Further the protein content of the hemp seed is supposed to be very digestible. Many people noted their personal experience of finding that hemp seed protein did not cause bloating or gas, like some of their whey, or other protein shakes did. And, unlike soy which has super high amounts of phytic acid (that anti-nutrient that prevents us from absorbing minerals), hemp seed doesn't contain phytic acid. At the very least, this makes hemp seed a step up from soy.

Luginbuhl, April M. (2001). "Industrial hemp (Cannabis sativa L): The geography of a controversial plant". The California Geographer. 41. California Geographical Society. pp. 1–14. hdl:10211.2/2738. Hemp contains less than 1% THC, or tetrahydrocannabinols, the psychoactive property in marijuana. In other words, smoking hemp cannot create a 'high.' ... The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated.
