About a thousand people took to the streets of Buenos Aires on December 18 to celebrate a year of marijuana activism and call for the right to grow their own plants. The march, led by student groups from around the country, ended at the Argentine Congress building, where speakers addressed the marchers. We present two dozen+ photos from the day here, courtesy Argentine activists.

Marching behind a banner saying "No to the Drug Traffic," the protestors criticized drug prohibition as fueling violent drug trafficking organizations. Another banner called for "An end to ignorance, the right to grow your own, and education for responsible consumption."

The Argentine courts decriminalized marijuana possession for personal use last year, but cultivation remains a criminal offense. The Buenos Aires demonstrators want to see cultivation legalized as well.
