Legalization sets a precedent that undermines international law.

When the time comes, the US federal government will need to determine how to handle the INCB and their clear disapproval for adult use marijuana legalization. Assuming that American policy will eventually turn in favor of adult use regulation, the U.S. has two clear options: 1) knowingly violate international law or 2) attempt to lead the charge in amending the Convention. Violating international law may not have serious consequences from the INCB or fellow nations who are also looking to legalize marijuana for adult use, but it does set a precedent which could be negatively impactful in the future. The United States has a unique role on the international stage, and with this influence comes a level of responsibility. If the United States disregards commitments it has previously made, then that has the potential to not only undermine the international influence the U.S. has accumulated, but it also has the potential to encourage other nations to do the same. The U.S. has an interest in maintaining the credibility of international law, and such blatant disregard for an international convention could negatively impact this interest.
