SEATTLE — The crowds of happy people lighting joints under Seattle's Space Needle early Thursday morning with nary a police officer in sight bespoke the new reality: Marijuana is legal under Washington state law.

Hundreds gathered at Seattle Center for a New Year's Eve-style countdown to 12 a.m., when the legalization measure passed by voters last month took effect. When the clock struck, they cheered and sparked up in unison.

A few dozen people gathered on a sidewalk outside the north Seattle headquarters of the annual Hempfest celebration and did the same, offering joints to reporters and blowing smoke into television news cameras.
