An attendee, who wished to remain anonymous, wears a pro-marijuana shirt at the High Times U.S. Cannabis Cup in Seattle, Washington September 8, 2013. Washington state was one of the first states to legalize marijuana for recreational use after approving separate ballot initiatives last year, even as the drug remains illegal under federal law. The Cup features exhibitions as well as a marijuana growing competition. REUTERS/Jason Redmond (UNITED STATES – Tags: DRUGS SOCIETY) ORG XMIT: LAA03
