The Kansas House has endorsed allowing farmers to one day sell hemp, less than a year after the state authorized growth for research. But some would-be producers of hemp say the legislation is more or less pointless. The House passed House Bill 2173 on a 119-5 vote Tuesday. The bill still must go to the Senate. The legislation paves the way for Kansas to create a commercial program to grow hemp, the industrial textile form of cannabis that is a close cousin of smokable marijuana.
