Now is a crucial moment for drug policy reform. For the first time ever, leaders across Latin America are coming together in support of legalization, discrediting the United States' argument that drug production abroad causes American consumption, and demanding change to relieve their suffering under black market rule. Just this Tuesday, for example, Colombian newspapers reported that President Juan Manuel Santos is crafting legislation to legalize personal possession of drugs.

Riding out this momentum, legalization will make its historic, first-ever appearance at the Summit of the Americas this April. Encouraging nations to participate in the debate and support the end of prohibition is a petition that has already garnered more than 5,800 signatures.
