As a general rule, Americans don’t give much thought to Uruguay, a small South American republic with a population of 3.3 million. But Uruguay has embarked on a new experiment with marijuana legalization that merits close attention. As Ken Parks of the Wall Street Journal reported late last month, new Uruguayan legislation will allow individuals to grow as much as 480 grams of marijuana for personal consumption, and marijuana cooperatives with no more than 45 members will be permitted to grow just over two plants per member. The government will also allow for limited commercial production, but Uruguayan lawmakers have made it clear that they don’t want a domestic marijuana market dominated by large for-profit firms.
