I have read the entire hemp section of the Farm Bill more than once. "Hemp" is mentioned 72 times. That link contains the full text.
Dowling completely invented his anti-CBD-rich-hemp position out of thin air in order to try to make better hemp sound worse. As shockingly stupid of a direction as that may be for a supposed CBD company, it really is that simple. He figured if he couldn't win, no one should, and came up with the only propaganda that he thought/hoped could maybe level the playing field.
