ZD,
That is not your problem because kashrut agencies did no such thing. What happened was that Rabbi Elefant responded to a question from a reporter. And he said that they would be open to certifying canabis infused products for medical usage. Such items would need hashgocha and the OU was approached by the producer and the producer told such to the media.
Of course, the so called Jewish Reporter at the NY Prust made the story into something else, which swallowed and are now regurgitating.
