The Mexican Secretario de Gobernación (roughly, interior minister), Miguel Ãngel Osorio Chong, gave a fascinating talk as part of the formal national debate over cannabis policy that followed the Supreme Court decision affirming a personal right to consume the drug.
The striking  thing about the speech was its recognition that both prohibition and commercialization have unwanted consequences, and its hint that Mexico might be alert to the possibility of finding an approach to avoid both sets of dangers.
Of course no one who has been doing drug policy for more than about twenty minutes is ever truly optimistic that a government will find something intelligent to do when there are so many unintelligent alternatives, but watch that space.
