Illegal (includes decriminalization)
Where is weed legal in South America? In 2013, Uruguay made international news when it became the first country in the world to fully legalize recreational cannabis, and in the years since, the majority of countries on the continent have passed legislation or lessened the legal penalties for marijuana possession, use, and cultivation. Most have taken measures to set up legal, regulated medical cannabis programs. The situation across the continent for the most part still lags behind that of its neighbors in North America, but in recent years, legalization and normalization advocates in South America have had ample reason for optimism about what the future will bring.
In the meantime, take a look at where things stand on marijuana legalization in South America.
