Uruguay moved a step closer to becoming the first country to legalize marijuana, with lawmakers introducing a bill that outlines how the drug would be produced, sold and regulated. The bill introduced Thursday in the lower house of Congress would allow citizens to grow up to six marijuana plants and to buy 1.4 ounces of marijuana every month. It would also allow for the licensing of marijuana clubs with up to 15 members, 90 plants and an annual production limit of nearly 16 pounds. Advertising and exports would be banned, and a regulatory institute would be created to control the drug’s production and distribution. President José Mujica has promoted the legalization of marijuana as a way to reduce the addiction and crime associated with harder drugs. Supporters expect the bill to become law by early next year.
