Iowans could apply for a state license to grow the controversial fiber hemp if a bill which cleared the Senate Ag Committee becomes law. Senator Mark Zieman of Postville says it would give officials a chance to test hemp as a cash crop. Zieman says a hemp growing license wouldn’t be given to just anybody. Zieman’s father, Lyle — who was a state Senator until last year, tried to get fellow legislators to get rid of the statewide ban on hemp, but failed. Critics say hemp is too much like marijuana and people like Zieman are being used by those who want to legalize pot. Zieman says the plants are NOT the same and there are over 25-thousand products that can be made from hemp.
