Uruguayans will be able buy up to 10 grams of pot a week, enough to roll 20 joints, under new rules governing the recently legalized marijuana trade in the country. About 20,000 of the 3.3 million people who live in Uruguay are estimated to use marijuana every day. Mujica is expected to sign off on the rules in coming days. He proposed the landmark legalization law to undermine drug trafficking. Uruguay, the first country to legalize the growing and sale of marijuana, is being closely watched by other countries debating drug liberalization. - Ya Libnan
