In a CNN interview that aired last week, President Obama incorrectly claimed that moving marijuana to a less restrictive legal category would require an act of Congress. He therefore did not address the merits of reclassifying marijuana administratively. From the perspective of people who believe marijuana should be legalized for medical or general use, Jacob Sullum writes in Forbes, the advantages of such a move are not as substantial as you might think. But neither are they, as UCLA drug policy expert Mark Kleiman claims, "identically zero." Sullum says rescheduling marijuana would have some significant practical effects, perhaps the most important of which would be to advance a more honest discussion of the drug's hazards and benefits.
