“Uruguay became the first country to legalize the growing, sale and smoking of marijuana on Tuesday, a pioneering social experiment that will be closely watched by other nations debating drug liberalization. A government-sponsored bill approved by 16-13 votes in the Senate provides for regulation of the cultivation, distribution and consumption of marijuana and is aimed at wresting the business from criminals in the small South American nation. Cannabis consumers will be able to buy a maximum of 40 grams (1.4 ounces) each month from licensed pharmacies as long as they are Uruguayan residents over the age of 18 and registered on a government database that will monitor their monthly purchases.”
