Coletta Youngers, senior fellow at the Washington Office on Latin America said that the conference should also focus on Central America's drug problems and reduce violence caused by drug trafficking in this region.
She recalled that countries like Mexico, Guatemala and El Salvador reach high violence levels, which should draw the attention of governments to avoid its expansion to other countries facing drug trafficking.
Only in Mexico, over 47,000 people died due to drug trafficking violence, during the administration of Felipe Calderon, began a militarized campaign against drug cartels.
Youngers said that the 69 delegations should discuss alternative policies to combat this global and complex problem.
However, she rejected the proposal to legalize drugs due the fail of repressive strategies to fight drug-trafficking.
"It is important to discuss the decriminalization of drug use and address it as a health problem," she said.
