When the hemp amendments were being considered, EPA had undertaken the unusual step of inviting public comment, which is required only for new active ingredients. With the rapidly growing number of acres planted in hemp as a result of the 2018 Farm Bill,  additional registrants can be expected to seek to add hemp as a target crop, although such future amendments are not likely to be the subject of public notice. In the meantime, however, EPA continues to assert that no pesticides are legal for use on cannabis being grown under state medical and adult use programs.
