The Mexican Supreme Court is delivering a challenge to the country’s historically strict drug laws, adding to the swelling debate in Latin America on the financial and social impacts of the war against substance abuse.

The New York Times reports that the criminal chamber of the court’s vote declares the right for individuals to grow marijuana for personal use. This ruling is just a single step toward legalization, and only applies to a single entity who brought the case to the courts. The decision does not eliminate any of Mexico’s current drug laws.

The decision from the Supreme Court indicates a changing opinion in Mexico, where the cooperative effort with the U.S. on The War on Drugs has had few lasting victories. Drugs still flow into the United States from Mexico, and the flow fuels corruption in the Mexican government, often to violent ends.

This case has started a debate over how effective jailing drug users actually is in a country that is considered one of the most conservative, in terms of drug-related legislation. More and more people are questioning American strategies in ending drug trafficking, which is causing the government to look toward new methods.

Uruguay legalized marijuana in 2013, which led to the slow creation of a marijuana industry in the country. Chile just had its first crop of medical marijuana. Canada’s new prime minister has talked previously of legalization for his country.

Wednesday’s ruling only applies to the Mexican Society for Responsible and Tolerant Consumption, who were denied a license, and took their case to the courts. For full legalization, the justices would have to rule in favor five times, meaning eight of the eleven members of the entire court would have to vote in favor.
