Colombia's President Juan Manuel Santos, left, and OAS chief Jose Miguel Insulza, shake hands at a joint press conference about a regional study on the illicit drug trade, presented by Insulza to Santos at the Presidential Palace in Bogota, Colombia, Friday, May 17, 2013. The $2.2 million study which emphasizes drug abuse as primarily a public health issue, makes no firm recommendations, instead suggesting several possible ways to stem the illicit drug trade, which has fueled violent crime and corruption and even destabilized governments.
