One Year Since Marijuana Became Legal in Washington

Posted: Updated:

SEATTLE, WA - Friday marks the first anniversary of the day several state laws in Washington took effect. 

In Seattle, hundreds of people are expected to celebrate the anniversary of when Marijuana became legal, by lighting up beneath the Space Needle at a party permitted by the city.  

Marijuana activist Ben Livingston says it took him three months to persuade the city to grant him the permit, which was amended on Thursday to double the party's capacity to 999 people.

The free event begins at 4:20 p.m. in a tent set up behind a double perimeter fence at Seattle Center, with any pot smoking occurring out of public view.

Gay marriage has also been legal for one year now. Auditors say since Washington state legalized gay marriage, same sex couples have made up 17% of the marriages in the state.

In the first 10 months of this year, more than 7000 same sex couples tied the knot in Washington state, nearly two-thirds of them women.
