Paul, who is widely believed to be eyeing the presidency, introduced a separate measure in June to stop the Drug Enforcement Administration from using federal funds to go after medical-marijuana operations that are legal under state law. A similar version of the amendment introduced by Reps. Dana Rohrabacher and Sam Farr easily passed the lower chamber in May, underscoring marijuana’s growing national acceptance.

Paul’s press person has said that the new amendment, if enacted, would go beyond the Farr-Rohrabacher legislation by providing a more formal framework for protecting states that have enacted medical-marijuana laws.

While passage of the amendment is unlikely—it’s not even expected to come up for a vote—the news of its introduction was excitedly written up by a host of advocacy sites, including Hemp News, Stop the Drug War and Ladybud, where advocates encouraged readers to contact their senator in support of Amendment 3630. “When calling or writing, remember that you catch more flies with sugar than honey,” advises one post, presumably meaning you catch more flies with honey than vinegar. “Reframing the medical cannabis issue as a human-rights issue, not a partisan one, will also help.”
