SEATTLE (AP) - Residents of Washington, Oregon and Colorado won't just be considering whether to let adults buy pot at state-sanctioned shops when they vote next month on legalizing and taxing marijuana. They'll be voting on whether to let farmers grow marijuana's far less potent cousin - hemp - for clothing, food, biofuel and construction materials among other uses.
But don't expect farmers to start growing it, at least not immediately.
The passage of the measures would create the familiar clash with federal law, which prohibits growing the plant for industrial, recreational or medicinal purposes.
Farmers who say they have enough to worry about with drought and crop diseases don't want to also be left wondering whether federal drug agents will come knocking.
"Farmers are already engaged in a high-risk endeavor," said Roy Kaufmann, a spokesman for Oregon's pot initiative. "That weariness of potentially facing federal action is just too much of a disincentive."
The three ballot initiatives to regulate pot like alcohol have garnered much attention, in part for the hundreds of millions of dollars they could bring into state coffers and for the showdown it could set up with the federal government.
No state has made recreational pot legal, and these measures would be the first to set up state-sanctioned pot sales.
The Justice Department could try to block them in court under the argument they frustrate federal antidrug law enforcement efforts.
Less well known is the effect the measures would have on hemp and the possibilities they create for another fight with the federal government.
Nine states - Hawaii, Kentucky, Maine, Maryland, Montana, North Dakota, Oregon, Vermont and West Virginia - have passed laws allowing hemp cultivation or research, and supporters of the latest measures say they would be another shot across the federal government's bow.
Oregon's earlier law, passed in 2009, allows the state to regulate hemp production; the initiative on the ballot next month, Measure 80, would allow unregulated hemp production.
While medical marijuana patients and those who grow for recreational use have been willing to risk federal prosecution, a viable hemp crop would be much larger than many of those grow operations, putting farmers at risk of severe mandatory minimum sentences in federal court. Hemp and marijuana are the same species, cannabis sativa, but are genetically distinct.
Hemp has a negligible content of THC, the psychoactive compound that gives marijuana users a high. It's also grown differently, in tightly packed plots to maximize stalk height rather than widely spaced to maximize branching and flowering.
