The U.S. war on non-smokable hemp hurts the environment and the economy, according to a new report from the free-market-promoting Reason Foundation. To wit: Hemp fiber requires six times less manufacturing energy on average than polyester fiber, and requires less pesticides and water than cotton. Hemp can be used to make paper, fiberglass, and cement, generally with less energy use than alternative materials. It could make a lovely cellulosic biofuel, were cellulosic ever ready for the big time. And in case you needed a reminder, says the report: “Marijuana cultivated for drug value contains between 3 and 10 percent of the active ingredient, tetrahydrocannabinol, or THC. Industrial hemp typically contains 0.3 percent or less of this active ingredient — as a result, it has no value as a drug.”
