If clothes were made of hemp, there would be no lint problems. Hell, when they got dirty you could just smoke 'em.... 
Actually in some places you can buy shirts made from hemp and they last 100 years or so. On going controversy on why we cannot grow Hemp in America. As far as smoking the stuff, may as well smoke catnip or dried parsley.
Farmers in my area want to grow hemp as for some reason it improves the soil, and the uses are quite amazing, boots made of hemp last and wear better then Moose hide. Farming Expos are one way to see how this plant is can be turned into material that is as soft as silk to make clothing and upholster furniture that wears better then horse hide.
Cotton industry and the Chemicals Company's are scared to death of loss of money if hemp is allowed to be processed. What will happen to the cardboard industry and the loggers that find less need for wood pulp.???
