Today a court in Argentina ruled that it is unconstitutional to penalize citizens for possessing marijuana for personal use, provided they consumed it privately without hurting anyone else. From the article:
"The unanimous ruling makes Argentina the second Latin American country in the past four days to allow personal use of a formerly illegal drug.
The case in question involved five young men who were arrested for having a few marijuana cigarettes in their pockets.
Supreme Court Justice Carlos Fayt, who at one time supported laws that make personal use of marijuana illegal, told the state-run Telam news agency that "reality" changed his mind.
Argentina's action came amid growing momentum in Latin America toward decriminalization of possessing small amounts of certain drugs."
According to Wikipedia, Argentina is the second biggest country in South America and has a population of roughly 40 million.
