In a Sunday interview [9], Colombian President Juan Manuel Santos called for the global legalization of marijuana, but said his country could not be the one to lead the way. Santos also called for a tougher, smarter approach to international drug trafficking and hard drug use.

Colombia has made progress in its fight against cocaine trafficking in the past 20 years, managing to destroy first the Medellin and then the Cali cartels and subsequently seeing a reduction in the violence that had plagued the country. But a legion of mini-cartels have emerged to take up the trafficking mantle, and Colombia remains a world leader in cocaine production.
When asked by his interviewer whether marijuana legalization could be a means of further reducing the violence, Santos said he would support legalization, but only if it were a global move. "Yes, that could be an answer, provided everyone does it at the same time," he said.
Colombia would not undertake such a move itself because of national security reasons, Santos said. "For Colombia, this is a matter of national security," he explained. "Drug trafficking is what finances the violence and the irregular groups in our country. I would be crucified if I took the first step. We need to insist on more multinational actions on drug trafficking and innovate the ways we are dealing with it," he said.
"In other countries [Europe and the US] this is mainly a health and crime issue," Santos continued. "We need to look at all components, one of them being targeting the assets in this business. But we need to do so on a global level. We must discuss a new approach, looking at all the components: The profit and the crime that follows drug trafficking, the fight against money laundering, trade with arms and so on. These are all effects of drugs."
Or, more precisely, global drug prohibition. And so, the consensus continues to crumble.
