A demonstrator carries a sign reading "Get Rid of the Weed Pass" during a protest rally against the new marijuana buying policy in Maastricht, southern Netherlands, Tuesday May 1, 2012. A policy barring foreign tourists from buying marijuana in the Netherlands goes into effect in parts of the country Tuesday, with a protest planned in the southern city of Maastricht. Weed is technically illegal in the Netherlands, but it is sold openly in small amounts in designated cafes under the country's famed tolerance policy. The government has said that as of May 1, only holders of a "weed pass" will be allowed to purchase the drug, and nonresidents aren't eligible. (AP Photo/Peter Dejong) less
