2013 Seattle Hemp Festival

Clay Graeber, 20, of Bothell, Wash., smokes marijuana from a glass bong at the opening day of the pro-marijuana rally Hempfest in Seattle Thursday, August 15, 2013. The haze of pot smoke might smell a little more like victory, after Washington and Colorado became the first states to legalize marijuana use by adults over 21. Having won at the state level, speakers will concentrate on the reform of federal marijuana laws. Image: Associated Press
