William Randolph Hearst spent a lot of time and money getting both marijuana and hemp criminalized in the early part of the last century. His motive was to change the way we produce paper (he owned lots of forests and wanted to move from hemp pulp to paper pulp). So, our laws criminalize a fibrous plant, not a psycho-active substance produced by one strain of that plat. Having yeast produce THC does an end run around our silly laws.
