Cloth

Hemp

Hemp grows well without herbicides, fungicides, or pesticides and is naturally anti-bacterial/anti-fungal. On an annual basis, 1 acre of hemp will produce as much fiber as 2 to 3 acres of cotton. Hemp grown for industrial use is very low in THC (the psychoactive chemical in marijuana), thus making industrial hemp useless as a drug. There is no chance of intoxication from the use of this cloth.
