Smart ass. Hemp fiber can replace cotton everywhere that cotton is used. It's a longer, stronger fiber, but just as flexible (i.e. "soft and comfy".)
Look up "hempcrete" for construction.
Then there are the benefits of hemp seed in one's diet, and it's suitability for producing bio-diesel fuels that can run in diesel engines without modifying the engines.
Last but not least is producing paper at 4 times the rate per acre than pulpwood, and without the harsh chemicals required by the wood pulp paper industry.
But that's why hemp was made illegal -- it threatened too many "new industries" of the time.
